I have a 6.5 hp engine on a Troy-Bilt shredder that won't

Customer Question

I have a 6.5 hp engine on a Troy-Bilt shredder that won't start. I used it last fall and it started fine. What could have changed?
JA: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?
Customer: Fuel is in the tank. Half is left from last fall. The rest is from this fall. To my knowledge there is not a shut-off valve separate from the throttle.
JA: Do you plan on doing the work yourself?
Customer: If possible.
JA: Anything else we should know to help you best?
Customer: It fired a couple of times, but no more. Instructions say to have choke on until the engine starts. I think that's all.

Can you remove the spark plug? With plug removed, was plug wet or dry? If wet, it may be flooded. If dry, no fuel to the cylinder. Ground the plug to the metal of the engine and see if you have spark when cranking at the plug tip.

Give me a few minutes to try that. I have installed a new plug.
Expert:  Curtis B. replied 3 months ago.

OK, if it has spark, put a teaspoon of fuel direct into the cylinder, re-install the spark plug, and see if ti will start for a few seconds. If it does, carburetor is not delivering fuel.

Give me a few minutes to try that. I have installed a new plug. plug was a little wet, but I don't know how much is too much. Also, I did not see a spark when grounding the plug.

The engine has always been a hard pull to start. I have a riding lawn mower that is like that too.

It must be getting some gas since it fired twice before, but perhaps not enough to continue running.

Did I lose you?
Expert:  Curtis B. replied 3 months ago.

So it has to be fuel supply problem. Have you removed the carburetor and checked it for any gummy deposits? And checked the fuel supply passage the needle valve has to open and shut? If you have an all metal needle valve, there will be a rubber seat in the upper passage. This seat can swell and restrict flow into the float bowl.

I cleaned the carburetor, and was able to start the engine. It ran for quite a while then quit. I'm guessing there is more impurity that needs cleaning in the carburetor. I believe you fixed the problem, but will let you know after this cleaning.

OK< let me know!
