Hello, I have been working on a unstyled G for a little while now. I pulled the old carb off, sent it away to get cleaned and rebuilt and found out that it was in really rough shape, cracked bowl and also cracked in a couple other places. It wasn't even the right carb for the G as it was off of an A. As I restore it, I wanted it to be 100 percent original so I ordered the correct carb for it that had been all cleaned, rebuilt and ready to go. Everything has been cleaned and I have good fuel coming from the tank with no restrictions. I put the new carb on and go to start it and it will only run on full choke. It also acts like it's freezing up. i also replaced the gasket also. Any suggestions what could be going on?
