Where can I get hard to find carb parts

[Travis M]

I have a big zenith updraft carb with 4 bolt flange that works good, but I want to get some or at least find a place to get kits for it. I have some numbers off of it, but can"t find much on them. It has 5 jets that look like holley jets. The number I can find on it is 10690D it looks like. Anybody have any info on it? Here is a picture, not a good one but it might help


I would also like to find an extra float for it.

don't know if this applies to your situation, but a friend had a big carb on an 800ci 900 and he made an adapter that he could screw holley jets into

I know Shipman has modified a few of those big zeniths and put adjustable load screws in them. Trying to tune that thing in by changing those jets can get very frustrating.

Have you tried McDonalds Carb & Ignition out of Jefferson, GA. phone 706-367-4179 (They have a web site).

Travis i had the same carb on my 900 around 850 ci send it to shipman you will like it hope this helps joe. PS It takes a very serious diet to get that thing to 4500 lbs and when you get there it will be nose heavy.

We are thinking about sending the carb to him, and I doubt we get below 4500, or at least pull at that weight anyway. Our newest carb problem is that we can't get the float valve to seal up. After running for a while the fuel pump starts to push fuel past. May need to lower the pressure.

Travis you do need a pressure regulator that needle/seat wont hold much psi.Later joe
