Relist: Answer came too late.
Did you try running without the air filter on? Did you refer to manual to make sure linkage is installed properly? Try adjusting the governor.Were you able to open the service manual link above?
yes ran it with out air cleaner .it does rev but it is real sluggish.i tried opening throttle valve by hand its sluggish .is it possible the muffler could be plugged.i tried choking it at wide open thottle no change
Adjust the gov and see if any difference.
adjusted gov.as per manual no change.it sounds like timing is retarded .it back fires thru carb when is shut off it back fires thru exhaust
I can't do anymore for you so I opted out so others can help solve your problem.

Welcome to JUST ANSWER small engines, let me try to help you !! Have you removed the flywheel and replaced the key? It only takes a small amount of deviation for the key to throw the timing off. I assume the engine has not been apart, where the internal timing between the crank and cam could be off one tooth. Is the coil positioned correctly on the flywheel with .010 clearance? MUffler could be checked, just loosen up the flanges and try it. do you have the electric solenoid in the base of the carburetor? It could be blocking the main jet opening.???
i will take a look at those things.it will take few hours to get back to u thx.
OK>
