holly 1050 90 jets squared otherthan that havent touch it any help would be great thanks
pull out the 3rd circuit air bleeds, drive it and see how it does. if it cleans up alot, leave the bleeds out. remember, when you're setting idle on a dominator, you HAVE TO ADJUST BOTH IDLE SCREWS THE SAME AMOUNT don't just adjust the frt and think you're doin it right, cause that's not right. my mixtures screws are all 4 about 1 1/2 turns out.
nutha thing i've noticed about dominators, they like alot of timing at idle to get the vaccum signal up. i'm locked at 36 and after the initial warm up, i can idle around all day and never have to tap the throttle to start the boat warm.will do and yes for every 1/2 half turn i go on the front the back gets it is there a power valve in the front metering block and can i change the air bleeds
Very good point Tom!nutha thing i've noticed about dominators, they like alot of timing at idle to get the vaccum signal up. i'm locked at 36 and after the initial warm up, i can idle around all day and never have to tap the throttle to start the boat warm.
this can cause problems in itself if you have have a pretty lumping cam. As the motor surges up due to the cam, the distributor advances alittle, then lopes down and the distributor retards back, in the mean time the signal to the carb is all over the place and adding to the problem. Lock down the advance mech. and time at 35 or put in a heavier spring and see if it helps any.got the weakest spring in a msd pro billet 35* total adv. with the black adv. bushing
it stumbled because with the heavy spring the timing backs off when the R's drop to a point lower than the light spring. If you have to run an advance mech., then put in a different bushing that limits the degrees to less movement, and the timing won't drop back as far from total and the stumble will go away. On a motor that just couldn't be locked I ran 28* initial with 38* total with a bushing and a light springwith the heavy spring it had a stumble
