[suddethtray]

nobody really

I've not figured out how you got it a half tooth off. I do not know if the crank is swappable but I think it has a good chance that it is.

[suddethtray]

i think maybe the chain has stretched

[Rebel]

If the timing marks were all lined up there shouldn't be a problem. I personally always take an awl or a file and mark across the timing chain and the sprocket when I'm tearing something apart to have extra reference marks, of course I line up the factory timing marks too.

If your chain has stretched, I'd get a new one.

[Rebel]

I have a message into a parts house about the crank for you.

[Rebel]

The crank will fit, there are more than one size of gears for the oil pump though so you need to check that out.

i got it in line and rode it bout 12 ran great i cut iot off and then it would not crank back and i have no clue .it has fire the plug has wet look and if u hold the throttel wide open and hit the starter it wonts to crank but wont any ideas

[Rebel]

A wet plug won't fire well at all, you are getting too much gas in there.

We may be speaking a little different terminology when you say crank and when I say crank.

To me a motor being turned by the starter is cranking over, if it is not trying to run but is turning over, it could be the wet plug issue, is the automatic choke stuck in the closed position?

i meant turning over the engine it wants to start if u hold throttle wide open. get what i am say im a country bumpkin lolll so what u think it just ran fine for 12 mi cut it off and wont START BACK
