falconvan Posted November 20, 2011 Report Share Posted November 20, 2011 I spent the whole day rebuilding one of these yesterday; had it apart and back together a few times. I found the video on You Tube from Mike's Carburetors and brought the whole thing in the house and put it together step by step with the video. Here's the problem Im having, I cant get it to pump fuel. It seems like the accelerator pump is sticking in the bore but it's brand new and everything is clean. Ive actually tried two different pumps; the one that was in it looked to be in decent shape. If you pull the cap off the side and unscrew the main jet it will pump gas out the hole but not when you screw the jet in. So the jet is clogged, right? I can see light and blow right through it so it's good. So I think maybe the pump is wore enough that it wont pump through the jet. I put the new pump from the kit in and it just sticks in the bore and wont move. Everything else in the kit fits but could I have the wrong pump?? I'm stumped. :confused: Quote Link to comment Share on other sites More sharing options...
randroid Posted November 20, 2011 Report Share Posted November 20, 2011 falconvan, The leather on the new pump is dry and shrunken and won't slide well but if you were to dip it in a little gasoline it would soak up the liquid and become soft and lubricated. It's easy for me to say what's wrong from a thousand miles away but that's what I'd try first. Am I correct in assuming the idle jet is not screwed closed? Probably wouldn't make any difference but I'm trying to save paper and postage by making as many guesses as I can in one reply. -Randy Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted November 20, 2011 Report Share Posted November 20, 2011 actually when shrunken they slide too well..the leather is no longer touching the sides of the pistorn chamber and thus it just travel bypassing any pumping action...once these are dried out they can actually reach a point that they cannot be saved...soaking in oil is a better method of relaxing the leather and the possibility of stretching it back to some sort of half use..but this will be short lived..Napa lists these on the average seperate from the rebuild kits for most all Carter carbs...they may have to reference these from a bood..but some are posted online...I found the listing for these seperate while looking for a carb kit for a 60 model Carter BBD Quote Link to comment Share on other sites More sharing options...
greg g Posted November 20, 2011 Report Share Posted November 20, 2011 Are both check balls present in the pump? they must both be there and be free to move in order for the circuit to work properly. Also then must be in the correct holes. one small and one larger, but I forget which is which. Quote Link to comment Share on other sites More sharing options...
Young Ed Posted November 20, 2011 Report Share Posted November 20, 2011 Small ones goes under the accel pump. And a new accel pump is available by itself from napa. Quote Link to comment Share on other sites More sharing options...
Frank Ollian Posted November 20, 2011 Report Share Posted November 20, 2011 Linkage installed properly and not binding? Quote Link to comment Share on other sites More sharing options...
falconvan Posted November 20, 2011 Author Report Share Posted November 20, 2011 Yeah, my check balls and linkage is right. I'll try and cross reference the model number on the carb and see if I can come up with something for the pump. Really frustrating; i'm so close. I might work on the wiring for a bit and do some research on this. Quote Link to comment Share on other sites More sharing options...
