I did a compression check and found all cylinders are within a few #'s of each other. Here are the averages
1= 112
2 = 112
3 =110
4 = 115
5 =115
6 = 110

I rebuilt the fuel pump yesterday which helps the overall performance, but it does not help at all in the low rpms. I did not yet pull the carbs. That will be next after these two questions.

1 - Per the wiring diagrams, there is a idle control module identified, but the engine does not have one installed. Could this be part of my idle problem?

2. - Since the engine runs great at mid and high speeds, could this be as simple as just an idle jet replacement, and if so, can that be changed without removing and disassembling all the carbs?

Thanks for all the help
