I recentley got a Hanmar9 110cc ( YG152FMH engine). Ran hard and strong then stalled and stopped. It is an automatic. If you press the starter button the atv starts to role. It acts like the clutch is engaged. Hard to push (feels like the engine is turning over). I never got that far involved with it. Am I going inthe right direction, thinking it is the clutch.
Would anyone have (if there is such an animal) a good service manual for this or where to get one. Not a parts list, but a service manual.

 

i have never heard of this happening before but ya, something between the engine and the wheels is locked into place so it is probably a clutch belt stuck in place.. no idea how to go about fixing it tho. sorry

 

I ended up replacing the clutch and everything seems to be running for now.
A few things I have experienced so far are the following:
Wiring connections I thing is a given. These will happen
1) Never run the engine with the shipping oil.
2) The glue holding the fuel filters together will start to disolve (not sure if this because we have the alcohol in the gas), it will happen.
3) I had one of the jets come loose on the carberator causing it to run real rich and would not stay running. It was almost just sitting in the float bowl. Just had to screw it back in.
4) Chain falling off. The bolts seem to losen up. Replace any bolts with elastic nuts or use Locktite.
5) Rear shock to stiff. The shocks on the front are the same, but the springs are lighter. Use the same style spring from the front for the back and then dial it in.

 

haha ya that jet came out of mine and i lost it, i just filled the hole with gasket sealer and adjusted the fuel mix with the main needle!!
