Monojet Problems
This is my first post on this website... ive been coming to it for about a year now and its like heaven on earth. Anyways, in 73 or such, my gramps bought a 68 from a guy that used her as a worktruck, all i know is it had a cracked exhaust manifold on it but he replaced it, which turned out to be worped lol... Anyways My dad was a mechanic and was intending on rebuilding the little 250 but he got sick and later died and at the time I was 4ish. But i can remember my gramps drving it through town, and i was with him the last time it was on the road... it died in an intersection... that was the last time he drove it off his land. But about 3ish years ago he gave me the pickup as a 'pidler' and about a year ago he ended up dying. Since my dad died when i was so young, he was like my second dad, so ive really been itching to restore it being that it kinda means alot to me and all, Well, im only 16 and not really much i can do... but i have some know-how So, in about july of 07 i began fixin her up, choped the muffler off, changed the oil (she has still got installed a franz oil cleaner), new air filter, new plugs and wires, and she was running beautifully (being that that was all i have done to her) then disaster... the carb backfired... so i rebuilt it... and theres where i need help, i finished it in about a month and installed it and she started right up, then disaster... again... there is a part that connects to the throttle that is a gas vacuum or some such and it wont stay connected... can anyone give me some pointers?
(sorry for the crappy details and spelling and all)

Re: Monojet Problems
Welcome to posting. Sorry to hear about your father and grandfather passing. It had to be hard on you and it was nice of your grandfather to pick up the pieces. I think it is great that you tackled the carburetor at such a young age. There are a lot of us who woudn't do it, now, at three and four times your age.
The linkage you mention....have you had it off at all? If you did, then I assume that you were unable to get it back on the way it had been, right? Is there a clip that fits into a hole and locks onto that link or does it have one end that has to be turned, like a key, and inserted? I don't have a one-barrel to look at. Can you go to a parts store and look at one of theirs (assuming they have one) and compare it to yours? Maybe then you can see something that will enable you to fix yours. Good luck.

Re: Monojet Problems
thanks, it has no key or anything like that, just a rod... that fits into that hole... if im making anysence. ive visited autozone and all and there all abunch or retards. bolivar is nothing but rednecks and the nearest salvage yard is closing down (it sucked in the first place) but ive got an 87 dodge that we are looking for a new gauge cluster for so when im at the better salvage yard then i will check there.

Re: Monojet Problems
Welcome to the board and glad you're fixing up the old truck. Sure looks like it's going to be a nice project. Stay focused on it even if it's a little at a time and stay tuned to this forum for any help you may need.
Here's some pics of a monojet carb I have. It looks different than what you have but as Chevloray mentioned, you may be able to get a look at one in an auto parts store or maybe a junkyard. I'll take a look at the one on my 68 GMC later and see if it's like yours. |

Re: Monojet Problems
The link going to the accelerator plunger on your carb is backwards from mine. See if you can turn it around to match the picture.
Also, the link that goes to the other plunger (the one you say comes off) should have a pinched end on one side to keep it from coming out of the hole. Look closely at the pic I sent and see the pinched part. That plunger should move up and down freely. Basically, when the bellcrank rotates, the accelerator pump plunger moves down and the other one moves up and vice versa. |

Re: Monojet Problems
I agree with 68GMC. Ive bent plenty of them in so they stay in the hole.
