The Stovebolt Site Forums The Shop Area General Truck Talk monojet carb leaking down ??

My 1970 292/6 has a monojet carb. Every time I start it, if it sits more than a few hours.I have to prime it with gas to get it to start.It seems like the carb is leaking down and emptying the bowl out into the manifold. I know the old 4bbls use to leak from the bowl and we use to epoxy them. Is it the same problem with the monojets? The carb is still on the truck so I can move it around. I am going to get a kit and go through it, Just wanted to know if there was anything to look out for?

I got the carb off today monojet part# on the carb is 17054306 is this the right carb for a C50 with a 292 ??

Just sit tight, some will be along with some answers. I have had my Mono-jet apart a lot of times tuning it, just can't remember if there is a way for the fuel to leak out the bottom. There must be or else yours wouldn't be doing it! You sure the accelerator pump is working? Do you see fuel spray when you move the lever? that is if it has fuel in it! Joe

I,m with Joe. I have rebuilt many Monojets & have neverhad that problem. I believe when you get through it will be fine. There are 2 different gaskets between the throttle body & fuel bowl. Make shure you select the right one & get it on the right way. The link from the throttle to the metering rod has a tendency to fall out. You can bend it in a little if it tries to work out.

some one has been in this carb before. The metering rod plunger has a rod next to it in the bore that fits into a slot in the plunger there is a small hole in one end of the rod It was not connected to anything? is it suppose to be or does it just ride up and down the bore, pushed up from the underside?? hope you can make sense of the discription. The accelerator pump is ok, and the carb looks pretty clean. I think the problem was induced by the last person here. I wish I had a diagram/exploded view of one of these carbs.

Oh ya, The accelerator pump was stuck 1/2 way down because the linkage on the bottom was bent and wired together by the last guy. I straightened that out and it seems ok

The "grand master" around this forum is called "Carbking". I know he hangs out in the engine section. I really think he invented the carburetor. Good luck

I found the small rod that hooks to the metering rod. I answered my owne ?. It was in a pile of stuff under the seat. (small hook shaped rod) can't believe I found it! I got a kit today, so I will rebuild it over the weekend an see how it goes. I can't see any reason to have the problem I am having?? dosen't seem like it can happen the way the monojets are set up. prety simple carb.
