Re: holley 1bbl carb trouble

Sounds like a metering rod. It shouldn't be seated in the jet. The rod should either be tapered or stepped. The rod moves up and down into the hole to change the effective size of the jet. Sounds like yours is closing the jet off, or making it to small at the wrong time. The rebuild instructions should have had an adjustment guide for this part. If you can't find it I'll take a look at a TSM, but will need to know the year and model the carb came off of.

> Hi folks, does anyone have knowledge of the holley model 1931 carb? I put a rebuild kit in mine last night and everything went smooth but now the car jumps off the line then kinda bogs or starves for gas.  one thing that that I did do that could be wrong is when replaceing the accelerator pump diaphram, I noticed on the metering block a rod and spring that pointed into a hole that the main jet entered.  THe rod looked like it was supposed to seat into that hole so I pressed the assembly down further until it did seat..now the car runs like crap.  What does that part do? is it supposed to be seated?  the main jet was a 55 if that matters.  thanks for any input.
