Eevn I agree that the 1411, a 750cfm is a bit much for a 305 but I really didn't have choice over it as the 1411 was on it when I bought it, a 600cfm carb would be a bit better. And of couse this isn't the original motor ether as for some reason the original owner swapped it out and left a good mess behind, nothing that can't be fixed but an annoyance for sure.
and currently I have no idea if its just some 305 he threw in with the carb or a 350. ether way it does run pretty good. I have to get around to running the numbers on it, if I can mange to figure out how.
