    Hey Everyone,

    I am new to this forum, so sorry if i miss post here. I have a pretty unique build here i have been working on for my girlfriends father. He has a 1967 CJ5 chassis with a 1942 Willys body on it that I have been restoring for him. The story goes, for those interested, that it drove great when he parked it here in PA. Took it all the way to the west coast, up and down the Rocky Mountains and eventually it made its way back here again, where after parking it in '82 it sat ever since. He finally let me take it out and get it running and cleaned up for him, and this thing is an absolute GEM. No critters found a home it, nothing was rotten out, im not joking when i say the tires still were full of air..

    I have since replaced the brakes in their entirety (master cylinder, all lines and fittings, and everything in the drums) The entire brake system was shot. The engine needed a new coil, cap, and rotor, but when those were replaced the thing fired up great and idled right from the get go. The throttle is very responsive, all the old gas has been flushed out, and it purrs like a kitten. Until you go to drive it.

    When i say this thing is an extremely sensitive throttle, i mean the most sensitive thing i have ever driven. And i am used to super sport motorcycles and some fairly higher horsepower cars. Its like the throttle is a light switch either on or off and no in between. Im pretty stumped as to what this could be. Throttle Return cable? Maybe something in the carb? Something to do with the choke? Maybe the clutch just needs driven a bit to be worn back in? Curious as to what all of your thoughts are on this. The only way i was able to drive it was starting in second. Maybe i'm just really bad at driving stuff this old? Ill post a picture if anybodys interested once I am able to get it out and shined up a bit.

    You mention two conditions, a sensitive throttle and then the clutch. Is the throttle very sensitive when its in gear or is the clutch " grabby" when engaging?
    How does the throttle respond when it is in neutral?
    The pictures of the throttle will help, the folks here will be able to tell a lot from looking at the throttle setup. We always are happy with pictures here.
    Looks like your first post, welcome to the forum from Michigan !

    Hello and welcome!:)
    I have a ‘66 with the Dauntless oddfire v6, all stock (still has the oil bath too) The only non stock is the exhaust, which is now long tube headers.
    The throttle is extremely sensitive! Cruising at a steady speed is fine, and throttle response is immediate (this is showing the accelerator pump is working as it should)
    But at slow speeds, a touch of the gas pedal will lurch the Jeep, almost like popping the clutch but you’re already in gear and moving. I believe it’s the nature of the Dauntless and the heavy flywheel giving all that torque :beer:

    leaving in first gear it will “bark” the rear tires unless you ride the clutch.

    If you adjust the throttle hold-back spring you should be able to adjust pedal pressure response to your liking. Welcome from Ga.

    Sheesh you guys are quick!! I apologize for not posting pictures in my initial post, didn't actually have any at the time. I uploaded a few i took tonight, if you have anything else that might help that would be great. So I spent a bit more time behind the wheel tonight, and had a few buddies drive it and it does seem like it is just the nature of the car Beech66Bum described above this. Does anybody know how i could possibly "censor" that inital lurchyness of the throttle?

    On to another few questions here while i have your attention, The transmission does seem to have quite a noticable whine while driving under throttle. Is that normal? I believe i read here one of the particular trans used in these jeeps has a good whine to it, how can i find out which i have?

    In terms of gearing, is there any easy way to find out what gears this has in the front and rear end?

    Also, that oil bath air filter, is there a common filter people run, or do people commonly just keep this on it???

    Can you relocate the throttle rod connection on the carb to where the lower bolt is? This would make a lot slower/longer throw response.

    Keeping the oil bath is a personal call, some like to keep it for originality and purist for a restoration.
    A modern open paper element works just fine. You will need the adapter to go from the 2 barrel to a 4 barrel. Edelbrock or Mr.Gasket 10” round air filters are a common swap.

    That tab on the throttle shaft that has the spring attached is the adjuster. Grab the tab with spring attached and slide it up the throttle shaft about half way and release it. The tab will lock itself on the throttle shaft and road test. You may have to try a few times until you get it where you like.

    Sorry for the late response guys, a bit of a crazy weekend. But you guys are awesome! All the help so far has been great. As far as the "touchy throtle" goes, it just really needed driven a bit more. It still is a bit of a handful sometimes compared to modern manual stuff. But nowhere near as bad as it was. Probably just needed the clutch and trans worked a bit. Fluid change really helped the whine too as well. I have not gotten a chance to check out the trans and dif to see what gears and trans it is, but will do that as soon as i can here today and report back. I haven't decided on what to do with the oil bath filter though, how do you guys plug the hole on the valve cover where the big breather goes to or the hose on the back of the carb? Honestly i do not mind the oil bath air filter. You guys are great, glad to be on here

    You can by a breather for the hole if you’re not going to use the oil bath. Save that grommet!
