OK Then I reversed a lot of things yet its improved how it runs?? I wonder what I fixed? Today I got it to idle by using the lean best idle method. It was warm enough out the choke was fully open when I started. It loped badly with the mixture screw out 2 turns. I ended up with it in to about 3/4 turn. I test drove it and it was great on the flat under 40. Accelerating to Hwy speed on a hill it backfired as second gear wound up near 35ish (it used to go to 50 and not even complain) and it backfired in the carb. It did it again in 3rd gear near the top of winding out also well below where it used to go. It was doing this before I rebuilt it apparently switching the primary/secondary jets.) I got home and changed the timing to be faster as it was loping a bit. This left me with the mixture screw at 1/4 turn or less and the timing advanced past the mark I think I remember reading before. 5BTDC. I washed it and cleaned it up then did the same trip over the hill and it still backfired (smaller) yet it had more power in 4th as it kept accelerating as it climbed in 4th. This thing used to have tons of torque to pull up hills. Any suggestions on how to proceed? I'm disturbed by your information Pennyman1. I wonder if I shouldn't just order these jets as Geez linked to and install them????? Here are the the jetting sizes for a 32/36 DGAV relating to a 2000cc engine- Main jet - (primary throat) 1.35 (secondary throat) 1.30 Air Correction - (primary throat) 1.75 (secondary throat) 1.45 Emulsion tube - (primary throat) F50 (secondary throat) F66 Idle jet (primary throat) 0.50 (secondary throat) 0.50 Idle air (primary throat) 1.50 (secondary throat) 0.70 I wonder what changed since it ran so well before I broke the balancer belt and kept driving it not knowing that is what happened. I only discovered that after I blew the head gasket in an overheat. I've posted for a radiator fan shroud in Wanted.
