WO CARBURETOR HEADS UP
Take a good look when buying those hard to find WO Carter WWII JEEP Carburetors, not all of them are made for JEEP, The Carter WO Carburers made for the PE-95 will not work on a JEEP. The bore of the throttle body is much too small among other differences that make its' components unuseable on Jeep It is made to run either at idle or governed 1800 PE-95 RPM. I can remember when these were offered NOS by the hundreds thru DRMO 50 years ago and bought unseen by dealers only to discover the error the hard way.

Re: WO CARBURETOR HEADS UP
Interesting. Would one of these PE-95 carbs happen to have an idle and a full throttle stop screw ??
That is what is on my CJ. I bought the jeep and eventually plan to restore it, but it is "my project" and my stuff is always last thing in the shop.
One thing I noticed was the additional "High Speed stop screw". I drive the jeep around the farm and up & down the runway and I have noticed a lack of high speed power. Runs great up to about 35 MPH. Won't do 40. My nephew can out run me on his 4 wheeler.
Now you have me wondering ??

Re: WO CARBURETOR HEADS UP
I don't have a PE-95 Carburetor here to go by, but the PE-95 Intake manifold bore is also a lot smaller than the A-1166 for the JEEP and the throat of the throtle body is about the size of a Quarter which is much smaller than the JEEP version.

Re: WO CARBURETOR HEADS UP
So would a PE95 carburetor come with a "407" stamped throttle body?
In other words, do "407" throttle bodies come with different venturi diameters?

Re: WO CARBURETOR HEADS UP
Different diameter, different number. The range of the throttle control is different as it is controlled by the Governor.

Re: WO CARBURETOR HEADS UP
Soooooo, get the genset carb, change the base to a 407 or a 6xx base with the correct bore, rejet the whole carb. You will end up with a ww2 float bowl with the correct patent numbers. correct float bowl top with the circle c and no other numbers, take the airhorn, pull out the goofy choke parts, and replace them with a post war shaft and ww2 or civi cable clamp assembly. The link from base to acc pump might be the right one with the cap and spring for a shaft lock. What did I miss?

Re: WO CARBURETOR HEADS UP
Believe PRE-95 is a 567S or 572S Carburetor. Throttle Body is 427 with 3/4 Bore.
539S has a 1" Bore. What did Adam miss? Good question. At least many of you will be aware that the PE-95 Carburetor is very different.
Good job, Adam.

Re: WO CARBURETOR HEADS UP
The correct flange is 407...any other number isn't correct for a G503 in WWII. The 505 is for a WO 636 which is a CJ carb. I think Scoutpilot can comment on the internals, that's above my pay grade as have only sought out 100% correct WO 539s carbs or ones with enough of the CORRECT parts at a reasonable price to use to make up a correct 539 from a jumble of carbs with mixed up parts I had accumulated over the years until he started doing his high-quality rebuilds. I still have some parts left over from all the carbs I had awhile ago that Scoutpilot rebuilt for me. Unfortunately most of the left overs are not correct for a 539.
Carter parts charts do not indicate a part number for the BOWL, which means it was not available for a replacement. The flanges ended up with worn-out, leaking throttle shaft bores so over the years carbs for the G503 and some CJs were rebuilt using the same method....use what ya got. They were so interchangable for the most part that this method sufficed.

Re: WO CARBURETOR HEADS UP
Only if has the rounded tower and two vent holes on the face.correct float bowl top with the circle c and no other numbers
With that in mind, pictures of what you are starting with would be helpful.

Re: WO CARBURETOR HEADS UP
Looky, they are all coming out of the woodwork, thanks.
I did this on the run and did not have time to check any other manuals other than TM9-1826A ORDNANCE MAINTENANCE Carburetors (CARTER) December 1952.
