I have my engine running now since I swapped cams, I have changed the power valve as needed. I just can't get it to idle right. old cam was .244/.252 @.050" on a 110 lsa, new cam is 266/274 @.050" on a 106 lsa. carb is a 750 mighty demon. i know, i know, most of you do not like the demon carbs, but i have had good luck with this carb after I dialed in. it idled perfect with my old setup, now with my new cam, i have problems idling. i get it to idle good, but then if i put it in gear, it dies, or when the electric fan comes on it dies. seems a little rich at idle now. i have tried adjusting the mixture screws, best idle and vaccuum is about 3/4 turn out. maybe it's just the "nature of the beast" with a cam with this much duration. It wants to idle at 1200-1300 rpm, does this sound about right or a little high for this cam . I have not driven it yet, but other than idle quality, it seems crisp and responsive. any idea's? do i need to experiment with different size idle bleeds or idle restrictors?
