Crappy throttle response and detonation...Save me!!

[70_Nitrous_Eate]

Some other things to check (cause I don't think your timing is the problem)


I'm leaning to a fuel problem. Namely, engine isn't getting enough of it...

Check the following items in this order.....
Fuel Filter (just put in a new one)
Fuel pump (you should be able to read at least 4PSI at full throttle)
Power valve in carb (not opening)
Plugged jet in carb.

I once had a small rock (piece of sand) that plugged one of my jets on my old 2barrel 78 stang carb. When the secondary barrel would open, the car would stumble and die. That one took me a while.. car would drive fine until I put my foot into it a little!
