i watched the tuning video as well read the manual and have found somthing on mine that has me a little worried..... it says in the video that with the primary butterflys closed that there should only be a slight purtrusion of the fuel feed that looks like a line inside the bore...... it's supposed to look like a small square but it has a 1/8 line on mine due to the fact the choke is keeping the flaps from closing to where they should be....... has anyone ran into this problem??

A buddy of mine is running a speed demon on his 350. But his carb does not have a choke. We took the carb off and set the transfer slot so .020 was showing and the set the idle using the 4 corner idle screws. I am not sure about you problem but I would like to find out also. What size Demon do you have and how do you like it? We have my buddy's carb about 1/2 way tuned in. We still need to work on the accelertor circuit. It has a slight bog when you first hit it. Good luck and sorry I could not help.

i have a 750 vac sec, with an electric choke.........

i called demon and they said i had to adjust the screw thats hitting the fast idle cam........ it's the black arm thats connected to the choke... they said in it's deepest cut it's not suppose to hit it...... so i lossend the screw until it was fine....
