10 hp Troy Built chipper pull start frozen

How old is the fuel in the tank and also look into the tank for water from condensation. If the gas is older than 2 months drain the tank and the carb bowel.

sounds like there's a restriction somewhere, do new pipes have a big enough diameter to give the engine what it needs?

pull plug and try to pull start if moves than it was vapor locked clean plug and try to start if no movement with plug out than internal engine or pull cord jammed

is all I could find,They're only parts breakdowns.

try changing spark plug, if unit sits outside rain can rust the coil but I would try a new spark plug first and make sure it;s gaped correctly

There is a blockage in the outlet from the fuel tank, there is a filter in the tank and it is dirty. Try it anyway. Stephen.

If fuel is leaking from the fuel filter, replace it. If fuel is flowing freely into carburetor and overflowing, it is likely the float, needle and seat.

It takes good gas, good spark, and good air for a gasoline engine to run well. The next thing I would do is put a new air filter in it.

Either or do one of two things if the motor runs pretty well Start the engine and run it full throttle. Once there if it has a high speed jet turn the screw in to start with until the engine stumbles a bit and then turn it back about a half turn. When you turn it in you should here the engine peak out. .If it is blowing black smoke out the exhaust it means the high speed screw is to far out so turn it in until it smooths out.If the engine smooths out then you have cured the problem. Good luck.

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help
thanks
