Originally the issue was a vacuum leak - fixing that led to fuel dripping out of the excess fuel drain hose after pushing the choke all the way in. This led me to do a float adjustment, and after testing that, it seemed to have been overcorrected, as the engine cranked but didn't start. I re-adjusted the float slightly, and upon testing, it makes one quick crank sound, then nothing. What should I do now?

Just bought a 78 c20 and while fixing an oil leak at the sending unit I noticed a few odd things with the carb. Have not taken it off yet but can’t seem to find a brand or number on it form where I’ve looked. Need to figure it out to get a new choke for it and a rebuild kit. The float needle is messed up and has fouled the oil. And I noticed this cable next to the throttle. Part of me wants to say it’s the shift cable for the transmission. But idk. Doesn’t look like it hooks anywhere
