After a long debate with myself I finally rebuilt my Monojet carb. Now the truck runs worse than it did before I tackled it. I carfully took it apart and soaked it in solvent. Blasted compressed air through everything. Replaced all the stuff that came in the kit and adjusted the metering rod and float levels according to the instructions. Now the truck has no power, when you step on the throttle it makes a blah, blah, blah sound until the RPM slowly climbs up. No backfires. At idle it sounds fine and you can rev it up in park and it doesn;t have the same problem, but put it in drive and you have to be real gentle on the throttle it get anywhere. I'm really choked!!! BTW all this is with a warm engine and no choke. Before the rebilt it would bog a bit when you hit the throttle hard, but only for a second or 2.
One suggestion was problem was in transition from idle circuit to main run circuit. Going to try and put the metering rod and float back to around where they were before I tried to follow the instructions. Engine is a '70 250.
