i have an 87 b2200 with a good running engine. i doesn't smoke when cold/ after looking in top end of engine appers to be a very clean engine. ran fine then one day put new blower motor[for heater] in and ajusted idel.. when i drove down the road it started to missfire or it seemed like that. when i steeped on the gas it quit running. i thought it was the acillerator pump so i rebuilt the carb. it ideal now but when i steep on the gas it seems fine. when i drive it and steep on the gas it stops running. and after ajusting the idel it started to smoke like a white smoke like it flooded.. after rebuilding the carb it still smokes white. it doesn't burn any oil at all. what do u think might be wrong?

Check your fuel pressure take the fuel pump and fuel filter out of the pic-both checked out-When you pull the throttle back the accelerator pump should squirt fuel if its okay-makes sure when the engine is fully warmed up that the choke plate is fully open .Check the ignition timing with a timing light and also readjust the A/F mix and curb idle to specs we stop here till you comeback with some results.
