Should the vacuum be that low.....??

Old hot rod guy down the road has the old dwell meter gauge which I hope to coach him on showing me how to optimize the settings...

Any suggestions...?

I will need to install a massive spring on the throttle...... driving it on the back field gets very jumpy and my heavy boot keeps punching the accelarator.... that little sucker will spin all 4 wheels on wet grass/mud like crazy....... way too much torque and pep......

Hi Bob

What are you getting for fuel pressure? This could play into a lot of issues with the different carbs. The runs good then stops sounds like dirt is get loose in the carb. This could actually be coming from the old gaskets inside the carb. Also be very careful of the little balls and springs and look for dirt in the springs.

The oil pressure of 40-44 is ok that's what the pressure re-leaf is set at with the long oil lines and the remote filters we have both effectively added an oil cooler. The result with mine is even at 400rpm idle it is running around 40 psi. As to the other readings I'll have to bring that info in from the computer in the shop. I'll try to post that this evening.

The gas peddle hop is what I mean I lost my cruise control.

When a cab starts acting up from a bit of dirt here and there just rev the motor up and pull the choke until the revs die down and it'll usually pull the offending crud through the jets and cure the problem.Sometimes you have to repeat the procedure a few times to get results. It's a way easier than removing and disassembling the carb.
