I have a Rochester 2G in my O/T daily. It was bogging out rich on acceration. I put smaller jets in. When I get on it, it bogs out at about 1500 rpm, then picks up and hauls ass until about 2500, bogs again, then hauls ass again until about 4500-5000. Ive tried everything I can think of. Carb is fresh and not dirty, its getting plenty of gas also. Plugs are looking pretty black. Too small of jets kicking the power valve in? Jets still too big? Power valve not working right? I dont get it.
