Tuning Demon carb
I used to have a 750 DP holley with 70/76 jets. I now have a 750 speed demon mech. secs with 68/75 jets and it still runs rich.
Should I jet it down further or do I need to do something else to the carb? Any help u guys could give me would be great as I don't have much experience at demon carbs.

I hate to answer a question with a question...but does Demon even use the same jet numbering system as Holleys? I know some of BG's jets used to use a different system..so a 68 BG jet was not the same as a 68 Holley jet.

Not sure bout that but the jets I have in it are made by holley I have a ton of them from playing with my two other carbs that I've had in the past.

Well then..double check the basics. Float level good, PV is intact, etc, etc, and if it's all good, then you might need different size jets with the Demon.
