about to rebuild the carbeurators on my 89 150 -also need to decarb the motor -should i decarb it before or after i rebuild em ? as far as i know this motor has never been decarbed so i should get a pretty good smoke show !!
doesnt matter to the decarb process, but if you need to rebuild the carbs, I wouldnt run th emotor any more than you have to until its right
