But yes, the when the TDC mark on the flywheel is aligned the two marks on the camshaft should be aligned with the top of the cylinder head or pretty Damn close. When I rebuilt my 500's top end I remember my cam marks weren't totally flush with the head but they were very close. Mine runs perfectly. Why are you thinking it jumped? If it did I would replace the chain and the tensioner along with the guides if they are worn.
I had replaced the stator prior to this and put the case back on just to test it before sealing it back up, so it needed to come back off anyway, but i do know about the inspection plug.
The reason I think it may have jumped time is when I was trying to start it, after fixing my "no spark" issue, it wouldn't fire up and I was getting back pressure through the carb, which enough pressure to blow the fuel pump in half. Looking at the marks on the cam and the mark on the flywheel at TDC, they don't seem like they're lining up like they're supposed to. Doesn't seem like there is excessive slack in the chain, but if it did jump time then I'll be replacing chain, guides and tensioner.
Not sure if its on compression stroke or not, but I know no matter which turn I'm on on the flywheel the cam doesn't seem lined up with the top of the head.
What is your opinion?
Thanks for you input!
