1982 22r with Weber 3600 , had it standing on it's rear today a few times and each occasion I had to stay in the throttle some to keep it running. It's been on the truck 6 months with zero issues besides today. Some additional info I'm running a bed mounted fuel cell it was full, electric fuel pump below the bed and a good manual pressure regulator under the hood.
Is this just something common with these carbs or is there something I can do different short of fuel injection to keep it going when climbing at steep angles ?
