    No. If you want to know more about the dashpot we talked about them in a whole thread here once.

    It just keeps the throttle from slamming shut.

    OK: In reading about the dash pot.....I'll get a new one.... I found the quote below.


    So.....is that correct....counter clockwise.....?

    I have the plugs wires on the dist cap going clockwise in that order.....
    If it's counter clockwise.....then it might start....

    That would be correct on the firing order clockwise rotation for the dist.

    I might have been unclear. Should the the plug wires be 165432 going counter clockwise.

    Cyl 1,3,5 are on the drivers side. 2,4,6 are on the pass side. Looking down on the dist cap from the drivers side #1 is located at approx the 7 oclock position. Start there and go clockwise around with the firing order.

    the simplest way i know to put it,<dist rotation> pull the cap turn over the engine see which way the rotor is turning,put cap back on after you get it back to TDC compression stroke line #1 plugwire up in postison with the rotor and follow with installing the wires in the correct order in the same direction that the rotor was turning

    HOOYA It started....won't idle yet, and needs timed,...but it started.
    I did find a 90% broken, (inside) wire from dist. to coil.....fixed it.

    Now, from the photo above, can anyone tell me what type of carborator it is, and were are the idle speed screws.
    I hope to have it idling soon....!

    rocherser and screws should be in front near the bottom,some of these were sealed @ the factory,and you have to drill out the plugs to acess the screws,if it is original there should be no plugs,they started sealing them up @ the factory in the late 1970's

    OK: Well, The Jeep idles now....I set the timing , and thought I would be ready to go.....LOL
    No such luck.
    It idles pretty good, sounds like a Harley. But, when throttle is applied, it dies....if throttle is then removed....it will cough and then idle again.
    I blew out the fuel lines with air from the bottom of the fuel pump.....
    It did seem a bit better for a few min after that...but then the same.
    Has a plastic see through fuel pump that looks clean and fills 1/3 full with gas.

    I idled back and forth on the driveway, in 4 wheel low, but at the slightest hint of acceloration......die's....Once or twice it did act like it might actually accelerate, but
    sputtered and died.
    Starts back up good.

    Any idea's.....?

    Kaiser_Willys told you where the idle mixture screws are, not the idle speed.

    I've highlighted the idle speed screw.

    No problem with that. I turned it all the way in, and then out two turns.

    I don't know if that would cause the engine to die when throttle is applied, but I don't think so.
    It seems like it gets starved for gas, or maybe the timing gear is wrong.
    I got a dwell meter, but haven't tried it yet.
    My question now, is what would make the engine die when the throttle is applied......?

    OK....I read this thread again....and others.....could this happen due to the dist being a tooth or two in the wrong position in the oil pump.
    If so, and if I take out the dist. does the gear just spin around on the shaft....and, how would I know if I am to turn it a turn forward or a turn back.....!
    Also, when I was timing it, and advanced or retarded the timing to far in either direction it made a whistling sound....is this a hint to something....?

    I know this thread is long, and I'm back were I started, but....it will run.

    Next, the vacuum advance thing is almost into the fan. Is that a hint that the dist is wrong....?

    Finally, in hooking and unhooking the dist vac hose. the nipple attached to the carb came out with the hose....could this be the problem....will J.B. Weld etc fix it.

    You need to turn your idle screw in until the idle speed is ~650 RPM for a stock V6 setting.

    Recheck everything. What's your timing set at? You didn't say. You can't just assume you're off a tooth unless you know where you are to begin with...

    I've said this before, I'll say it again. The distributor will drop in many ways, it doesn't matter where the vacuum advance points as long as you can adjust the timing.

    Sparky....OK...the timing is at 5 degrees. and yes the timing does adjust. I can see the marks go either way with turning the dist. and getting to O or 5 degrees is no problem.

    I have a dwell and tach meter, never used it yet....so I will go over everything and report back. The PO's said they were attempting to adjust the carb, so who knows what it's settings are.

    I won't attempt to remove the dist.....just check and report back.
    Thanks !

    Sounds like you're timing is good.

    Set the idle high enough that it will idle, start adjusting the idle mixture screws until you get ~20" of Hg. Then turn your idle down a bit, readjust idle mixture screws, turn the idle down, etc. Until you're within specs.

    Check for vacuum leaks.

    .


    ~20" of Hg.....OK, I think the mixture screws are the exposed kind.

    I don't know what Hg is...?

    As for vacuum leaks, is there some type of smoke test or some way to detect them....?

    20 inches of mercury, Hg = Mercury (you know the symbol for mercury on the periodic table?)

    Spray carb cleaner around the carburetor base and watch for the vacuum and idle to decrease or starting fluid and watch for an increase in vacuum or idle.

    Sparky: Ok and Thanks....I did a bit of reading here on vacuum leaks and gages, and followed some links to more on vacuum leaks.
    I will do all of it and report back
    Thanks Again
