Raised the float levels to the upper line... car bucks under moderate throttle now.

Time to move it back down and step up to a loud ass electric fuel pump. I guess when they dyno my car I'll ask them to run it in 3rd, just to be safe, if I don't have a new pump on by then.


I've decided to leave the PVCRs alone, don't want to risk screwing up the metering block/ tune. No time or money for that right now. I'll live with the 13.5 6th gear cruise.

Bucking was a result of an MSD wire melting on the header. Fixed it, but not before I moved the floats back down problem solving.

Still intend to go electric when I get the time to wrench on it again.

It could also slosh out the vent tube if it's too high. This is a common problem with Holleys on 4x4s.

Install extensions.

Jet extensions won't help in the offroading example. When you are climbing a steep hill with light throttle you are only using the primaries which are getting fuel. What happens is that the angle is enough that when you hit bumps the fuel gets pushed out of the float bowl through the vent tube and it falls into the venturies which in turn floods the carb. If you where giving it full throttle in that situation then you would want to have jet extensions on the secondary jets.

Bowls are running out of fuel, I've had this problem before. Need an electric pump. Mechanical one was maxed out 200hp ago.
