I am gearing up to do my first carb re-build and have read everywhere that blowing compressed air through all passages and drying with compressed air are essential steps in the process. I don't own an air compressor so I was wondering if there was an alternative. Would that aerosol air can they use to blow dust off of photos and computer parts work...I would question if it had enough PSI to do the job and or if it had some kind of chemical in it that wasn't good for the carbs...any thoughts?
