Need help tuning Demon carb
I have a Chevy 4.3L V6 with a 525 CFM Road Demon carb. I was getting a large
stumble off idle and at 3000-4000 RPM. I installed smaller squirters and it solved the off idle stumble but there is still a large flat spot from around 3000 to 4000 RPM. If anyone has any advice it would be greatly appreciated.
Thanks

sounds like your secondaries are maybe opening too much too soon, try adjusting them to open a little less, should get ya therejust because your car is faster, doesn't mean i cant outdrive you... give me a curvy mountain road and i'll beat you any day

Well I've sure gotten old too so don't worry about it! I've had two bypass surgeries, new knees, fought prostate, cancer and diabetes. I'm half blind, can't hear anything quieter than a jet engine,...
