She Won't Start
My 85 will spin but won't catch. During start, I can hear a slight poping at the exhaust. Very minute poping. I set ignition timing with No.1 piston at TDC and the distributor rotor pointing towards the No.1 spark plug wire. I measured 40+lbs of fuel pressure on start. Spark plugs are wet with fuel.
Any ideas?

Re: She Won't Start (GRX)
I just posted how you should orient the harmonic damper and rotor on another post.
I just went through this same problem with another Forum member a few days ago.
Take a look. http://forums.corvetteforum.com/zerothread?id=814722

Re: She Won't Start (JAKE)
Well,I tried it but she still won't start. This time got a massive backfire through the manifold. What could it be? Did I adjust the valves wrong? :(

Is that finger tight with the lock nut or spinning pushrod ?
If your confident with your adjustment than I would look at spark plub wiring and initial static timing. :cheers:

Really? I looked in the number one spark plug hole and could swear I could see the piston top when I set the rotor. :confused:

Your grip could be stronger than you think
Are these stock rockers or roller ?
There're full roller rockers. Would that matter?
