Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
You mentioned that you check the battery. Did you load test the battery?
What happens in high mode? Does it die?
When you engage the pto does it die instantly or sputter a little while then die?
The throttle not going to full throttle sounds like you either have an air filter that is stopped up so that the engine is not getting enough air and choking itself out or you are actually going into the choke mode which would do the same thing.
The machine dying when you engage the pto sounds like a seat safety switch issues. What happens if you try to release out on the clutch and drive the machine with the pto turned off?
Let's try this, remove the air filter and see what happens when you go full throttle or engage the pto.
Have you checked the oil level?
The only other thing that I can think of is maybe the carburetor is over fueling so that at higher speeds it floods the engine. Have you ever noticed the engine being hard to crank when starting?
It definitely sounds like the carburetor is over fueling, especially if you can't start it in choke mode. You might check the choke linkage to make sure that it is not sticking or hanging this would cause the same problem.
Just let me know what happens.
I would focus on the carburetor as being a problem. It is most likely leaking and flooding the engine.
I would remove it, give it a good cleaning and install a rebuild kit. This should take care of your problem.
Thank you, ***** ***** been a pleasure to assist you. Let me know what happens once you do that.
