Did you line the marks up AFTER installing the cam chain tensioner? Also you had the cam lobes pointing down I'm assuming??? Is your cam chain stretched at all?

[tmmy]

yes i did it after i installed the cam chain tensioner, it was running just fine before i took it apart so i don't think the chain is stretch, it just seems like its always a little off. i can't get it to align perfectly

Go there number 4 and 5 you need to check and see if you have them,also make sure your lobes are down when you reassemble at TDC.

[tmmy]

yes the lobes are down and i was missing the decompresion plunger. i ordered them and they should be here soon. how do i install the plunger? does it just sit in their? is thier anyway i have to align the decompresion on the cam?

[Dannys440]

All that you have got to do is put the plunger spring in,then the plunger itself,Last reassemble,and it should run fine.
