Sorry, I don't get on every day. I'll have to look at my records to see where I'm at. I'll try to reply tomorrow.

 

sounds cool,i'll check tomorrow!Thanks for all your help,i really appreciate it.My car is starting to run pretty damn good finally.

 

What size squiters are u guys useing? And do your cars idle rich with the demon carbs? Mine sure does. I completely closed the sec throttle blades and idle mix screws and that seems to have helped a little. U guys have any more ideas? I'm sitting at 69prim and 75sec jets with #25 squiters.

i have 28 primary and 25 secondary squirters in my demon.i am at 70 primary 77 secondary jets,but still rich including at idle.I have my mixture screws about 1.5 turns out on all 4 circuits.Just keep playing with the idle mixture with a vacuum gauge,i managed to clean my idle up quite a bit by doing this repeatedly,and the car doesnt hunt for an idle anymore,it finally has a set RPM.I dont think we'll ever have a lean idle due to the size of the carb and cam combo.But i could be wrong,any suggestions from others?!?!
