First time poster... with a couple of questions.

Being a new guy, Ill say folks here are trying to help. Your choice of a speedway carb would have probably been changed if you had asked first. Speedway sells some useful parts, some good, some not so good. Carbs are not on the good list. Uncle Max only works on stromberg carbs, re bushes the throttle plates, new real stromberg parts thruout,
re does the finish on the whole carb, all new screws, all linkage replated, and its tested and adjusted on his flow bench before its shipped out. When you get it, you bolt it on and it runs perfect.

I too have rebuilt all kinds of carbs thru my life, but this is done right. Last one was about 225 if I remember, and they look like new.
