Carb tuning help after mods
Alright... here is the back story.
I added an electric fan and then at high rpm the engine felt like it would bog down, ya know kinda cut out.
Then just recently I added an FC-1000 ignition control module and the C-4 coils and now at like 6,000rpm the motor starts sputtering and cutting out.
Also, if I just floor the gas it just dies and then kicks like crazy and will take off... I think it is the squirters spraying that instant fuel.
So my question is, Do I need to go smaller jets or larger and at what increments should I start with. Also, how do I cut back on those instant fuel squirts... cause I am assuming that is over fueling the car on instant WOT.

Yeah, I have had the same Holley 650 Double pumper with #66 jets all around the whole time. But it has been a while since I have replaced the fuel filter. Thanks, don't know where my heads been on silly stuff like that.

High rpm sputter could also be attributed to weak grounding, or more likely ignition issues since you recently made some changes there. I assume you have set the timing correctly?
