Brozol 30/31 pic 3 test failure

[pernest]

Installed my old Brozol 30/31 pic 3 carb today to see if would perform as a back up carb.

Got the car started and warmed up but it nearly shut down a few times. I could see that there were problems so I cut ignition. Then I noticed some gas spurting from the tube at the carb top cover for a few seconds after shutdown. Removed the carb and reinstalled my working carb.

I had just rebushed the throttle shaft on the Brozol and don’t think this is an air leak issue. Any ideas?

Dead float? Stuck needle valve? Too much fuel pressure? That’s all I can think of for fuel exiting the vent tube. Take it apart and find out.

Yeah, I'd look first at a float/needle valve issue.

I do not know how to fix this. All I can say is it all works fine for me with what I use, Firefox.

Thanks. I took the carb top off today and noticed that I may have used a larger float than called for (one for the 34 pic 3 carb). Installed what I think might be the correct float. The needle valve seems to be working fine. Will install and check the carb again soon. I believe the float may have been the problem. Thanks guys!
