here some spec. 350,stock 883 heads ( i think thats the numbers) with 2.02 intake and 1.60 eg. valves, Phoenix dizzy base timing at 8* mild cam i can't remember the exact numbers but it's nothing wild, vacuum runs at about 8 Hg.,
now it idling real rich, fouling the plugs, smelling bad, and getting black smoke out the tail pipes I've try putting different rods and jets in there it. it helped a little bit as i made it 6% leaner than base. i just put another set in there today which made it 12% leaner than base, but this change is messing with my power mode witch is running about where it should ( Little rich ).
now here's the weired part the only way i can get it to idle smooth is take both A/F screws out, as in out of the carb and in my hand out. but this gets the engine racing a little bit. also i can't really go by tack readings as there is some thing goofy with that too it's hitting about 7000 rpm at 40 mph in second gear (t5) and about 3000 in fifth at 55 mph.
tomorrow I'm going to try and put a different coil in there that i have laying around just to make sure it not that. and I'll see if the rod change helped. i started to change my oil and had to go, now it dark out and i have no garage
. thanks in advance
also the carb has been striped and floats are correct there's probally some more info but my eyes are gettin heavy
