What will bad reed valves do?
Failing reed valves can result in reduced power at what should be cruising speeds. However, failing reed valves reduces the fuel and air mixture. This results in fuel being dumped into the carburetor with no flame to ignite it. The result is reduced power.
What causes a 2 stroke to bog?
Now regardless of whether it’s on a garden strimmer, lawnmower or chainsaw, whenever we pull the throttle on a 2 stroke engine and get a bogged down sound it’s almost always caused by an insufficient amount of fuel reaching the engine.

How do you know if a 2 stroke piston is bad?
Recognizing Symptoms
- Worn piston rings can cause incomplete sealing, resulting in lower compression and more difficulty in starting.
- Damaged or worn out reed petals will allow air to leak out, creating less cylinder pressure and starting/running difficulties.
Can a 2 stroke engine start hot or cold?
This isn’t a hot 4 stroke we’re are talking about here, 2 stroke engines are very easy to start hot or cold, and hard starting is a sign that something is not right in your engine.

What causes hard starts in a 2 cycle engine?

How to troubleshoot a 2 stroke engine with no fuel?
2 Stroke Engine Troubleshooting – Spark But No Fuel. As you read above this is assuming you have checked the basics, you know, gas is on, gas in the tank, choke is on.
