Briggs and Stratton Ready Start Problems (Engine Tips for Woodcutters)
Briggs & Stratton Ready Start Problems: Engine Tips for Woodcutters
The Briggs & Stratton Ready Start system is designed for easy starting, eliminating the need for priming or choking. However, like any mechanical system, it’s prone to issues. Understanding these problems and knowing how to address them can save you time, money, and frustration.
Understanding the Ready Start System
Before we dive into the problems, let’s briefly understand how the Ready Start system works. It essentially adjusts the fuel-air mixture automatically based on engine temperature, ensuring optimal conditions for starting. This is achieved through a series of components, including:
- Carburetor: Mixes fuel and air.
- Automatic Choke: Controls the air intake for starting.
- Ignition System: Provides the spark to ignite the mixture.
When things go wrong, it’s usually in one of these areas.
Common Briggs & Stratton Ready Start Problems
Here are some of the most frequent issues I’ve encountered with Briggs & Stratton Ready Start engines, along with potential solutions and cost considerations:
1. Engine Won’t Start
This is the most common complaint. You pull the cord, but the engine just won’t fire up.
-
Possible Causes:
- Old Fuel: Fuel can degrade over time, especially if left in the tank during the off-season.
- Spark Plug Issues: A fouled or worn spark plug can prevent ignition.
- Carburetor Problems: A clogged carburetor can restrict fuel flow.
- Low Compression: Worn piston rings or valves can lead to low compression.
- Ignition Coil Failure: The ignition coil might not be generating enough spark.
-
Troubleshooting Steps:
- Check the Fuel: Drain the old fuel and replace it with fresh fuel. Consider adding a fuel stabilizer to prevent future degradation. I always recommend using premium fuel, even though it costs a bit more upfront. In my experience, it burns cleaner and reduces the risk of carburetor issues.
- Inspect the Spark Plug: Remove the spark plug and inspect it. If it’s fouled with carbon deposits, clean it with a wire brush or replace it. Check the spark by grounding the plug against the engine block while pulling the starter cord. You should see a strong, consistent spark. A new spark plug typically costs around $5-$10.
- Clean the Carburetor: This can be a bit more involved. You may need to remove the carburetor and clean it with carburetor cleaner. Pay close attention to the jets, as these are often the source of clogs. Carburetor cleaner costs around $10-$15.
- Check Compression: You’ll need a compression tester for this. Screw the tester into the spark plug hole and pull the starter cord. A healthy engine should have a compression reading within the manufacturer’s specifications (usually around 90-120 PSI). If the compression is low, it could indicate worn piston rings or valves, requiring a more extensive (and costly) repair. A compression tester costs around $20-$40.
- Test the Ignition Coil: Use a multimeter to test the ignition coil’s resistance. Compare the reading to the manufacturer’s specifications. If the coil is faulty, it will need to be replaced. A new ignition coil typically costs around $20-$50.
-
Cost Considerations:
- Fuel Stabilizer: $5-$10
- Spark Plug: $5-$10
- Carburetor Cleaner: $10-$15
- Compression Tester: $20-$40
- Ignition Coil: $20-$50
- Carburetor Replacement: $30-$100 (depending on the model)
- Professional Repair: $50-$150 per hour (labor)
My Experience: I once had a chainsaw that refused to start after sitting idle for a few months. I went through all the usual steps – fresh fuel, cleaned spark plug – but nothing worked. Finally, I decided to take apart the carburetor. It was completely gunked up with old fuel residue. After a thorough cleaning, the engine fired right up. Since then, I’ve made it a habit to drain the fuel from all my small engines before storing them for extended periods. It’s a simple step that can save a lot of headaches.
2. Engine Starts but Stalls Immediately
The engine starts briefly but then dies.
-
Possible Causes:
- Fuel Starvation: The engine isn’t getting enough fuel.
- Air Leak: An air leak can lean out the fuel-air mixture.
- Dirty Air Filter: A clogged air filter can restrict airflow.
-
Troubleshooting Steps:
- Check the Fuel Line: Make sure the fuel line is not kinked or clogged. Also, inspect the fuel filter (if equipped) and clean or replace it if necessary. Fuel line and fuel filter replacements usually cost under $10 each.
- Inspect for Air Leaks: Check the carburetor mounting bolts and intake manifold for tightness. Spraying a small amount of starting fluid around these areas while the engine is running can help identify leaks. If the engine’s RPMs increase when you spray starting fluid, it indicates an air leak in that area.
- Clean the Air Filter: Remove the air filter and clean it with soap and water. Allow it to dry completely before reinstalling. If the filter is excessively dirty or damaged, replace it. Air filters are relatively inexpensive, typically costing between $5 and $15.
-
Cost Considerations:
- Fuel Line: $5-$10
- Fuel Filter: $5-$10
- Air Filter: $5-$15
My Experience: I had a similar issue with a firewood processor. It would start, run for a few seconds, and then stall. After checking everything else, I discovered a tiny crack in the fuel line. It was so small that it was hard to see, but it was enough to cause a significant air leak. Replacing the fuel line solved the problem instantly.
3. Engine Runs Rough or Misfires
The engine runs, but it sounds rough or sputters.
-
Possible Causes:
- Dirty Spark Plug: Even if the plug is sparking, it might be dirty or worn.
- Incorrect Carburetor Adjustment: The carburetor might not be properly adjusted.
- Valve Problems: Worn or sticking valves can cause misfires.
-
Troubleshooting Steps:
- Replace the Spark Plug: Even if the old plug looks okay, it’s a good idea to replace it with a new one.
- Adjust the Carburetor: Most Briggs & Stratton engines have adjustable carburetors. Consult your owner’s manual for the proper adjustment procedure. Generally, you’ll need to adjust the idle speed and the fuel mixture screws. Be careful not to overtighten the screws, as this can damage the carburetor. If you’re uncomfortable adjusting the carburetor yourself, it’s best to take it to a professional.
- Check Valve Clearances: This is a more advanced repair that requires specialized tools and knowledge. If you suspect valve problems, it’s best to take the engine to a qualified mechanic.
-
Cost Considerations:
- Spark Plug: $5-$10
- Carburetor Adjustment (Professional): $50-$100
- Valve Adjustment (Professional): $100-$200
- Valve Replacement (Professional): $200-$500 (depending on the engine)
My Experience: I had a chainsaw that was running rough and misfiring. I tried adjusting the carburetor, but it didn’t seem to help. Finally, I decided to check the valve clearances. Sure enough, one of the valves was out of adjustment. After adjusting the valve, the engine ran like new.
4. Engine Smokes Excessively
The engine emits excessive smoke, either blue, black, or white.
-
Possible Causes:
- Blue Smoke: Burning oil, often caused by worn piston rings or valve seals.
- Black Smoke: Rich fuel mixture, often caused by a dirty air filter or a malfunctioning carburetor.
- White Smoke: Burning coolant (if the engine is liquid-cooled) or condensation.
-
Troubleshooting Steps:
- Identify the Smoke Color: The color of the smoke can provide clues about the underlying problem.
- Check the Oil Level: If the engine is burning oil (blue smoke), check the oil level and add oil if necessary. However, if the oil level is consistently low, it indicates a more serious problem that requires professional repair.
- Clean the Air Filter: If the engine is running rich (black smoke), clean or replace the air filter.
- Inspect the Carburetor: A malfunctioning carburetor can also cause a rich fuel mixture.
-
Cost Considerations:
- Oil: $5-$10 per quart
- Air Filter: $5-$15
- Carburetor Repair (Professional): $50-$150
- Piston Ring Replacement (Professional): $300-$600
- Engine Overhaul (Professional): $500-$1000
My Experience: I once bought a used wood splitter that smoked excessively. The seller claimed it was “normal,” but I knew better. The smoke was blue, which indicated burning oil. I took it to a mechanic, who confirmed that the piston rings were worn. Replacing the rings was a costly repair, but it was worth it to get the splitter running properly.
5. Engine Overheats
The engine gets excessively hot, potentially causing damage.
-
Possible Causes:
- Low Oil Level: Insufficient lubrication can cause overheating.
- Dirty Cooling Fins: Dirt and debris can block airflow around the engine.
- Overloading the Engine: Pushing the engine too hard can cause it to overheat.
-
Troubleshooting Steps:
- Check the Oil Level: Ensure the oil level is within the proper range.
- Clean the Cooling Fins: Use a brush or compressed air to clean the cooling fins on the engine.
- Reduce the Load: Avoid overloading the engine. If you’re cutting thick logs, take smaller cuts or use a sharper chain.
-
Cost Considerations:
- Oil: $5-$10 per quart
- Engine Damage Repair (Professional): Highly variable, depending on the extent of the damage. Could range from $100 to $1000 or more.
My Experience: I once overheated a chainsaw while cutting a large pile of firewood on a hot summer day. I was pushing the saw too hard, and the cooling fins were clogged with sawdust. The engine started to smoke and lose power. I learned my lesson that day: always keep the cooling fins clean and avoid overloading the engine, especially in hot weather.

Practical Tips for Cost Optimization
Here are some practical tips I’ve learned over the years for optimizing costs in wood processing and firewood preparation:
- Buy in Bulk: Purchasing firewood in bulk (e.g., by the truckload) can often save you money compared to buying it by the cord.
- Harvest Your Own Wood: If you have access to land with trees, you can save money by harvesting your own wood. However, be sure to obtain the necessary permits and follow safe logging practices.
- Use Efficient Equipment: Using efficient equipment, such as a log splitter, can reduce the amount of time and labor required to prepare firewood.
- Dry Your Wood Properly: Properly drying your firewood can increase its heat output and reduce the amount of wood you need to burn. Aim for a moisture content of 20% or less.
- Maintain Your Equipment: Regularly maintaining your equipment can extend its lifespan and prevent costly repairs.
- Shop Around for Parts: When you do need to repair your equipment, shop around for the best prices on parts. Online retailers often offer lower prices than local shops.
- Learn to DIY: Learning to perform basic repairs yourself can save you a lot of money on labor costs.
Relevant Calculations and Formulas
Here are some relevant calculations and formulas that can be helpful in wood processing and firewood preparation:
-
Board Feet: A board foot is a unit of measurement for lumber. It is equal to 144 cubic inches. To calculate the number of board feet in a log, use the following formula:
(Diameter in inches)^2 x Length in feet / 144
-
Cords: A cord is a unit of measurement for firewood. It is equal to a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long. To calculate the number of cords in a pile of firewood, use the following formula:
(Height in feet x Width in feet x Length in feet) / 128
-
Drying Time: The drying time for firewood depends on several factors, including the wood species, the size of the pieces, and the climate. As a general rule, it takes at least six months to dry firewood properly. To estimate the drying time, use the following formula:
Drying Time (months) = K x (Moisture Content - Target Moisture Content)
Where K is a constant that depends on the wood species and the climate.
Case Studies
Here are a couple of case studies illustrating how I’ve applied these principles in real-world situations:
Case Study 1: Saving Money on Firewood
I used to buy firewood by the cord from a local supplier. However, I realized that I could save money by harvesting my own wood from my property. I obtained the necessary permits, purchased a chainsaw and a log splitter, and started cutting and splitting my own firewood. Over the course of a few years, I saved hundreds of dollars on firewood costs.
Case Study 2: Repairing a Chainsaw
My chainsaw stopped working one day. I took it to a local repair shop, and they quoted me $200 to fix it. I decided to try to repair it myself. I watched some videos online and learned how to diagnose the problem. I discovered that the carburetor was clogged. I cleaned the carburetor and the chainsaw started working again. I saved myself $200 by doing the repair myself.
