Thanks for all the replies! I took another carb off one of the other toros I have and the engine runs fine....7300 with a apc 16-8 and the stock muffler. I for the life of me cant figure out why the other carb went to crap. Theres no dirt or anything anywhere, the gaskets all look good cant see any tears in the diapram. The only thing that I did do differently on this carb is I removed the throttle return spring. Maybe that did something ???Anyway, Im gonna make a new intake and try a single barerel walbro,make reed covers and give it a try for ****s and giggles. hope everyone has a Happy new year![8D]
