I have a 1956 or 57 david bradley walk behind and replaced the carburetor with a Chinese made one. I think that was a mistake because I can't get it adjusted to run right at all. Acts like its too rich or slightly flooding all the time. It also at times revs to full throttle when just sitting still idling. The needle valve in the old carb was letting gas keep coming in after the bowl was full and leaking out the bottom of the carb and also flooded the engine. I should have ordered the repair kit but I thought the body might be corroded some and the needle valve wouldn't seat right.
The Chinese carb was $29 compared to ninety something for a Briggs. Probably a disgrace putting the Chinese carb on an American made machine like that.
Anyone have any ideas what might be wrong I could fix to get it running better?
