Is it starting and dying or can you just hear the starter motor ticking over? It could be too much or too little fuel. Not too sure about the C90, is it carb or injection? And is it 2 stroke or 4? Could be 1 of many things.

well for starters there should be a cover over that Stator and the stator should run in oil. Confused

its cdi i do believe, isnt it in the coil bit? ive checked the timing all over no sign of anything, it is an odd one for sure...

Hi, that looks like the points model, its under the round cover, take out the long bolt on the square bit at the other side of the engine, the round cover will come off.
check the points gap and the timing, if that fails, a valve might be sticking, check the clearences on the tappets, there under the 2 round covers on the head.

cheers baldy, well i popped that cover off, and all i can see is the face of a cog with 3 bolts on it, nothing to really adjust or check

how do you actually check the points gap and timing?

valves look to be moving fine... Mad

Tis a cub engine, the points (if it has them) act on the centre of the flywheel rotor. Only the older big block C90 engine has points driven from the end of the cam.

yeah i just realised now what the point is, you can adjust it through the holes on wheel on pic, ive adjusted it everywhich way yet nothing...

Could be coil or condensor playing up. Also check obvious things like continuity on the loom from the stator.

well got a spare coil coming so im hoping that fixes it, as that was the first bit that went, then the strator, continuity checked that and it fine...

cheers guys
