New Heads / Cam Running like Cr@p

ChunkFunky · 04-23-2003, 06:49 PM

I know everyone's going to say it's the lashing, which in fact I wouldnt be surprised but here goes.

bolted everything up with the new heads intake and cam, I set the lash acording to the posts people have made about the subject. I started it up for the first time and it ran like crap... very rough. So I shut it off and started it again and it wouldnt start.. it only starts if I press down the gas pedal, all the way.. then it starts and idles awful. My guess is the lashing is not right.

Even though I followed the procedure I found that I could get to the point of ZERO lash by tightening the nut by HAND, then I would do the 3/4 turn with a ratchet, but some seemed to go way too easy with no resistance and others seemed to have a bit of resistance and seemed to even push down the valves as I made that last turn.

I'll pull the valve covers and re do them, is there anything I could have done wrong with the cam install or the harmonic balancer install, it's all kinda keyd stuff it only goes in one way... the cam is a line up the dots thing and the balancer has a groove.

I can do them while it's running I suppose... though that could be a mess I imagine right?
