Okay, so I just need a logic/brain check here. I've been doing valve adjustments the Cap'ns way since I got the car, but Rich suggested I try a go/no go method to see if I can figure out what is causing my backfiring problem.
Basically, I need to get one valve open as far as possible, making sure that the OPPOSITE valve is as closed as possible. In this case, #1 exhaust and # 3 exhaust.
So if I'm looking at #1 exhaust and it is open (the rocker has play in it) then the #3 exhaust should be closed solid, correct?
Rich, sorry to post this for all to see, I'm just looking for an answer quickly so I can get this buttoned back up before it's dark. Thanks for your help!
