I flipped the pic. So are you saying the choke won't open? Why can't you pour gas in the front? LockDoc

Re: 72 c-20
Just under the fuel line where it threads into the carb, the rubber choke pulloff hose looks split, or is it just a bad pix.

Re: 72 c-20
The secondary lockout rod coming from the choke pull-off assembly is missing, not a spring. When you operate the throttle, do those flaps on top open? Those are the secondary air valve plates and should only open when the engine is warmed up and you are heavy on the throttle, never before then. It looks to be in poor shape. I'd recommend getting a reputably rebuilt carburetor.

Re: 72 c-20
The front is the only one that is supposed to open. The rear flap (air door) opens when you romp on it.
