The choke on the Twinkie II never worked correctly. It took too long to come off and it had to be adjusted way past the maximum lean mark to work at all.
A friend gave me a GMC Motorhome Q-Jet, same number as the one I already had, that I was going to rebuild. When I removed the choke I noticed there was a tiny plastic tube between the choke housing and the carb body, maybe an eighth of and inch in diameter and half an inch long. I had previously removed the choke from the Twinkie II and this part was not there. It was also not on a 403 carb I had looked at.
I installed this little tube on the Twinkie II choke and it now works perfectly. So here's my question.
It seems odd that the tube would be missing from both carbs that I had, both of which came from running engines. Has anyone else run across this? Does the plastic rot and they fall apart? Do people rebuild the carb and leave them out? Just bad luck?
What I am referring to would be where part #57 would go in this image, although here it is shown a just a washer.
