Only one way to measure belts, do you still hove the old one that worked? If yes, get a tape used to measure fabrics, yes it is a cloth tape Singer makes one. Measure the out side of the belt with the tape. I have tried two ways, one roling the belt on a bench got one measurement,,Came out the...

If you look at the cylinder you will see ridges in the wall. The piston is cocking and jams. Have experienced this on a 2 cycle.

I would say the idler pully is bad, is what you are hearing is the bearing.

Have you changed the fuel filter? After that long the filter deuterates, then it clog's the very fine screen in the carb. I think mine is an 027 no plastic heavy as a horse. Also changed the tank filter and cleaned that screen and it still runs.

Take the plugs out see it the machine turns over, if it does it has become Hydro locked (maybe a better word) I did get a more Amp Hour battery and pulling back the throttle when starting , as it turns over then increase throttle. Helped with my issue. My problem is the machine wants to run...

Have you checked compression? Have had different motors that would run forcing fuel in the carb. but would not start. Valves could be leaking.

Check the valve clearance, could be the oil seal on intake valve

If it fits, take the new main jet out and replace it with the old main jet. See if it corrects the problem. Turn the fuel off when changing.

Had one do similar. Had to make the intake gaskets thicker, was an air leak.

Springs look to tight, not allowing the governor to operate under a load. Is the unloader working? could be stuck in open position.

My self would make a filter. Has been some talk about washing filters. Not recommended, it destroys the air pockets in the filter. Oiling filters have to be careful some filters will not hold up , again crushing the the bubbles in the filter.

Is the starter a perfect match? If it does not start with a jumper batt. the Bendix might not be lining up with fly wheel. If not the case most likely the Batt. or starter. Loose connection, ?

Do you know the ambient temperature at the same times. Could be dirt under the shroud.
