I purchased a rebuilt Autolite 4100 recently... have not had much use since my car is still in primer with no windows... but I have taken it around the block and it love the power over the 500cfm edlebrock I had in it.
I recently changed the spacer to one that has a pcv intake. Upon getting things going again, I noticed gas pooling in an area on the carb adjacent to the fuel inlet needle.
I am not exactly sure the purpose of this circle... there is one on each bowl right next to the fuel inlet needle that sits within the bowl. Is this an area for a freeze plug that may not be sealed that well? Can I fill this circle with JBWeld?
I have reached out to the rebuilder of this carb and he has yet to reply to my email.
Over the weekend, I converted the automatic heat choke with a manual style... after running it a bit on the rich side, I really noticed the gas leak.
If you look to the left of the circle, you will see more gas. You can see what looks like a raised line in the corner... I cannot tell if there is gas also coming from it, but it kind of looks like that to me.
Not sure what to do? is this something that can be repaired if it is actually leaking from that spot as well?
Also, What should I expect from the carb rebuilder? Granted it has been some months since I bought from him... but I do not see how I could have caused this issue? Or if this is just the roll of the dice with these old carbs?
Thoughts, suggestions welcomed.
