Hi grumpy's
I have quick fuel 750 carb I'm been playing around with jetting this thing for about 2 months. The carb came with pri - 74 / sec - 84 jets, pump nuzzles front 31 / back 31, power valve 4.5, idle bleed jets - 70, high speed jets - 33.
Man I had stumbles off idle and 3000 rpm flat spots and then pick back up. And kinda flat when I put my foot to the floor - I have Little hesitation when running around 65 miles on the high way now - help on this.
I re-jetting down all the way 66 front to 69 back this made it real bad. So start re jetting back up 1 jet at a time. My jetting is 77/86 but seem like it could be even a little higher with the jetting "O" I change the pump nozzles 35/35 front to back and I install a washer in the front accelerator pump spring. My power valve is 2.5 high flow,
It seems to be running better but not quiet right on. I thought the carb was maybe to big but it seems to like bigger jets than what came in the carbs Is this right for a little 327 motor.
Motor specs, car is a 82 camaro
65 327 30 over motor, edelbrock air gap intake, 2" 4 hole spacer tapered, heads 210 runners valve's 2.02/1.60 chamber 54cc, aluminum heads, Pistons 30 over compression 10.5, spark plugs autolite AR3924 gap 45 are these the right plugs for my set up - help with this, roller rock arms 1.6 with stud gridles, Schneider race cam hdy durations gross intake 288 exhaust 296 at 50 230/238 lift 485/492, Gear drive, 1/2 gas line from the gas tank no return line - should I have a return hook up - help with this, Mallory ignition 6-al and coil, Distributor wysco, Timing at 12/38, rpm idle 800 vacuum 4.5 no vacuum leaks is this the right timing set up for my motor help on this, 4 speed manual with 373 rear, Tires 28x15 size.
"O" for got to ad this in there's a little black smoke in the tip of me exhaust pipe.
Any improvements you think I need to change or add would be helpful.
Thanks
Here's a pic of the motor
