The original subject was "Re: Ford Holley Carb.".

I've got a 3cyl gas 4000 that I'm rebuilding the carb on. It's got the Holley carb, and I think I've been having problems with the accelerator pump. I got the tractor from my father, and he wasn't too careful about running non-ethanol gas in it. Already I've noticed the "fine sand" looking grit in the carb. It's experiencing surging when I let off the clutch. I had suspected it was governor problems, but after exhausting that to no end and it still surging I'm now thinking it's the accelerator pump.
I've got a dumb question though-- what is the check ball in the accelerator pump? On mine it's hard to tell if they're there and just really froze up or it's plugs. Here's a pic of the accelerator pump stand. I labeled all of the ports "plugs". Is 3 the check ball you guys are referring to?
Thanks for the help.

I think its a check valve that's unobtainable and not behind none of the plugs you posted. It should be a EZ check you can push fuel one way but not the other way... Best I remember I just blow thru it. Go to CNH web site you may can get a break down on it are its in a manual I don't remember. That fine sand chit is in all of'em :twisted: NONE of these tractors have a decent fuel filter from the factory...

If you get frustrated with it I would like to have it... So far I have not had any takers :cry:
 
Well I found the check ball. It is underneath this screwed in portion. It had all kinds of junk in it that I was able to clean out.

I assembled the carb and put it back on over the weekend. Tractor runs great! I need to do some idle speed and governor adjusting on it still, but it appears that the surging has been reduced.

I appreciate the offer Hobo, but for now I'll keep the old Holley. Thanks man.
