seems out of the 5 carbs I have (all 650cfm) will not idle now that I have the firecore dist/wires on. have to jack up the throttle till on transfer slots or main boosters.

got the new OOTB 750cfm performer bolted on it.

changing the advance springs in the dist and this carb got me a good idle, crisp throttle response in N, idle in gear at a redlite with no mis-fire or problems while sitting in gear.

off idle stumble is almost gone but still there. not there when you step down 1/4 throttle.

now I am supposed to limit the mech advance so it does not advance too much at speed/WOT (where it still runs like poop)

cant even grasp how that's done and these "keys" they talk of no one seems to know or have??

so I idle around town and trips to the circle-k just to warm it up good.

I think this is where it will stay. I don't want to go back into the dist. at least I am mobile again with it. slow but mobile.

so it is what it is,looks good, sounds good, runs like poop.

I will settle for the 2 out of 3 and call it done.

back to the Harley project.
