Won't idle down....

Well, after rebuilding my carb and distributor etc on my 1967 M38A1 CDN2, my shake down drive went great. About 30 mins. and no issues. Since then, the jeep will start fine with the choke on the first or second turn of the engine. Idles fine, but after giving it a shot of gas it revs up fine, but seems to get stuck revving, somewhere around 1500 rpm or so. I have checked and double checked and lubed, greased, and cleaned the throttle linkage. It returns as it should, but the engine seems to hang there revving. I pulled the top off the carb and checked the float, but it was still set at 1/4 off the plate when inverted. It will idle down after 10 or 15 seconds, but it is really not driveable as it is.

Any ideas? I used the manual when I rebuilt it, so I am confident that the springs are in correctly etc. Obviously something tanked, but I am stumpd... I also plan on checking for any obvious vacuum leaks tomorrow.

Oh, and on a happy note, my wife and I found out yesterday that she is preggos, so there will be a new little jeeper in the house in Oct.

Here are some pics after the rebuild...

I cant' help with the carb issue but welcome to the site! Your Jeep look great!

I was surprised your M100 had the composite style taillights instead of the earlier pot metal units.

Thanks Clinto. I got the carb issue nipped, a gasket in the carb went wonky. Replaced, and runs awesome again.
