I was reading on another forum site that some guy had a similar problem and removed the heads and found a blown head gasket between 1 and 2. Could this possible cause the pop and if so, shouldn't I see some smoke (or water vapor) out the tailpipes? Could the kirban be going bad? When I adjust the Kirban, the gauge will move so does that mean it is ok? Also, I heard the kirban can be adjusted w/o taking the vac line off. Can someone confirm this? Thanks!
cant confirm it, but are you setting the fuel pressure with the vacuum off?? ive heard of some people having there pressure to 50 psi to cure the poping....
I set it with the vac on. So should I take the vac off and put it to 50? Also, can my Mass Air be too big? It is the big chrome Pro-M one..I have heads and cobra upper and lower though...
