My Jeeps all have their original carburators. YF, YS, and WO. I've had all down to nothing, and have gone to the school of hard knocks, do it yourself, and learned much from our mentor Mr. Rick, the Scout Pilot. I find the WO the most user friendly. The YF has a accelerator pump set up, that hates any snarf, and has a little U shaped outer connecting rod that must be right on in it's bend or adjustment for the whole carburator to work. The YS military carbs (waterproof) have vacuum operated accelerator pumps and metering rods that will make you feel at their mercy. One thing I learned on them, is the two covers that install over the rubber diaphrams can be warped. Bubba tends to just keep tightening the screws until he strips them out. I hate this guy! I found that wet sanding them on a flat glass in solvent works wonders in stopping the leaks from them. The fuel line in both the M38 and M38A1 has many leak points for air to get in and stop the priming of the fuel pump. As a result, you have to crank longer with full choke to get them started. To aid in starting in cold weather, they would install a cold weather primer, that literally pumped raw gas into the intake manifold. Standard in '51 and then option only after that. This also can cause more leaks. That's the main reason they were dropped after '51. So, in short, I use "Rouge Methods" and Scout has the tools for the job. I'm sure glad we all have him backing us up when we get in trouble, and the willingness he shows to provide free advice. I commend you for that! Signed, Carb Leaker

Sage advice and worthwhile information. I do appreciate the input. You sir, are welcome here anytime you wish to expound on the merits and drawbacks of these often cantankerous little devices that can give us so much pleasure and too many heartaches. I dub thee an Associate Professor.
Well, I'm no professor, but I sure have some trail experience. A fellows wife was disgusted with the group one time and said: " all you guys do is drive, drive, drive, and fix, fix fix!" That sums it up well I think. Oil
A trail tip: After you get your newly running Jeep pal out on the trails, it may decide to not idle. All new, what the heck!!!! I finally found the culprit is almost always a vacuum leak at the carburator base. That fat gasket with the "V" and staples holding the thing together will help you leak. What I do now as standard procedure is make two thin paper gaskets that match the fat one, and install top and bottom without any sealant. This helps with the leak the staples can cause. I also now put thin star washers on the mounting studs to keep the nuts from vibrating loose. Regular thick lock washers are too thick. With all carburators, it's very bad to crank hard on the mounting flanges, or for that matter all screwed together parts. They do not need this and you'll ruin your carb. Scout's favorite inlet filter with the glass site bowl is another fine recommendation. I find that my WO Carbs are amazing little guys and work very well. Oil

Hey Stephen! Welcome aboard! I don't get much call for help with a BBR-1 on a Champ so the best I can do for you is refer you to some folks who might be able to help. If these guys can't help you, I know a few more. SO click away.

Since you ask so nicely. I can test as many as three carbs in a day. Each of those could be put on and removed up to three times. I got tired of trying to fish the cotter pins I was using from under the Jeep or from the hot exhaust manifold. I have a few of these clips around and after a little tinkering with the basic design (grinding off 1/8" of the long leg) I inserted this little jewel and haven't had to go fishing or crawling (I confess. I cheated and used a magnet wand. But I still had to get down on my knees. ) again.
Always make sure the spring clip at the top of the Choke/ Fast Idle link is nicely secured, or else the link can fall off and proceed to wedge itself against the exhaust manifold and hold the throttle wide open..... At the worst possible time.... Wife and the inlaws where proud of me that day...

oilleaker1: At least it wasn't a Boss 429 Mustang. I'd help kick on that .

oilleaker1: Lee, you can have both and still have fun. I'll bet a run in a D type Jag would get your interest.

brucew: You can have all your Mustangs, I’ll settle for being a part of the ‘73 Z28 restoration project that’s going on in my garage right now. And I’d love to see some progress on my ‘64 El Camino. I bought the EC in ‘69 and the Z in ‘76, and still got ‘em.

brucew: Don’t know about a Jag, but I’d sure like to have an MG TC. They may not be fast, but they are the coolest looking little Brits ever made.

oilleaker1: They all had good models. One brand only for life means a closed mind. Give yourself a little variety. Sell the junk, keep the gold.
