OK, are you having an issue where if you manually move the cam it's springing back?

Customer: replied 1 month ago.
it does
Expert:  kwiggins29059 replied 1 month ago.

Thanks, ***** ***** will need to do is start the chain on the crank pulley pull it tight and put it on the cam while lined up by holding the cam then run the chain over to the tensioner side then apply the tensioner spring.

A lot of times there's two flats on the cams where you can put a wrench to hold it. If not you may need to use a small pipe wrench.

ok ive tried that it still the same the chain wont fit if both the sproket and the t is align its always advance by one tooth so the ,ark never align
Expert:  kwiggins29059 replied 1 month ago.

If it's advancing when the tensioner is applied you need to align it one tooth backwards.

In the picture it looks left of the T if you rock it back do the cam marks get any more level?

Customer: replied 28 days ago.

Thanks, ***** ***** chain new?

Customer: replied 27 days ago.
no its the original chain
Expert:  kwiggins29059 replied 27 days ago.

Thanks, ***** ***** chain wear is the biggest issue here. You should have immediate movement when turning the crank back to the T mark.
