Well the engine didn't run at all prior to me cleaning the carbs and it wouldn't run either after I cleaned them, full choke or not. The only way I could get some pop would be to spray starter fluid directly into the intake after removing the carbs while cranking the engine by holding on to the starter button. And even then it wouldn't run well, some cylinders would fire sometimes and once in a while, and the motor wouldn't really synchronize. The only problem the bike had prior to the day that it wouldn't start was that it was that the bike needed full choke for while when it was cold. Also more throttle (higher rpm) prevented it from stalling as easily. Once the bike was warm and running, there were no problems. After the engine wouldn't start, the first thing I checked after spark was the carburetors, but they actually looked pretty clean and I could see through all the jets and everything. I know for a fact there is an issue with piston ring/cylinder wall contact, because compression went up from 110 to 175 when I put a little oil in cylinder 1 to help seal whatever gap there might be. I just don't know if that low compression is the only thing preventing the engine from staring.
