moose man: Is the engine the old style? Early ones had air bleed carb,I had one where the fuel line nipple was soldered into needle assy,had crack in joint. Some had slide valve carb ,won`t run with out pressure or pump. Are the two carbs alike? Don`t like to tell you this,switch parts one at a time. Like we used to say ,when it don`t run put a PERRY on it!! Well this is a start. big max 1935
