318 Won't Start? And I tested as much as I could I think?

Well, I've used Gas to start fires before so it defiantly can burn. As for the current fuel it's in a brand new tank and some was taken out to check and it was crystal clear.
Another guy I know is helping and it is running, but very rough. He re-adjusted a bit more and the whole carb on the bench, and found the float too high, pump vent (to much travel), as well as a diaphragm only popping in and out instantly, on top of that the choke temperature switch. The suggestion from him is to return the carb I bought a year ago and start over again.
S.O.B. how could this be this much of an issue? It's a 2bbl Carb. I guess I'm at the point now where I will replace the carb and the choke temperature switch.


There is always a vapor coming off of gasoline and that's what's burning. Not the LIQUID fuel. That's why atomization is important. Liquid fuel running into a combustion chamber won't atomize (most of it anyway) and it is lost power.

Again, liquid gasoline does not burn.
