Hello everyone,

Finally got my engine in the car and my new Vintage Speed exhaust hooked up. My 32 vents are on back order so I put my 28’s in. I went to start it and had a heck of a time to get it to even run. Well to make a long story short my Petronix distributor ignition failed and my alternator light is dim when running but I will deal with that later. So I changed my distributor with a vacuum advance one and she fired right up! So I started to adjust the carbs using DannyP guide. I’m idling good at 900rpm but I can rev it up. It’s hesitating and backfiring 1500rpm and up. I’m stumped?

28 vents, 55 idles, F11, 185 air, 115 mains.
idle adjustment screw 1 turn out on all 4

Timing 28 advance@3000rpm

Fuel pressure 2.5 lbs (mechanical pump)
