Ok, I've got a few questions and found out some things while working on the car.

1. I found an oil leak of some sort down by the air pump. It's near the radiatior hose at the bottom of the block. Any idea what it is and if it is easy to fix?

2. Still having the problem of the car stalling and dieing out after the car warms up and the automatic choke kicks off. I've checked all of the vacuum hoses and they seem to be intact. Did some adjusting with some idle/mix screw; not sure which one it is, it was on driver side bottom, and it did absolutely nothing. I sprayed some Gumout and that helped things a little. My question is when you look down the carb on the passenger side, are you supposed to be able to see fuel spraying down the large opening or down the little opening closer to the driver side of the carb? I never see fuel spraying out into to large opening but I do on the smaller openings. Sounds like the carb may need tore apart?

Any help and suggestions are appreciated!

edit: I also found out that my 7 is infact an 83, not an 81 like I was told. I'm not sure if that makes any difference or not? Oh, and when the car stalls and dies out, it's almost impossible to get it started again.

bump for some suggestions

Hehe, I know what the 1. answer is.

Your Oil Metering Pump is leaking there buddy! Yea that's the thing that shoves oil into the combustion chamber and lubricates the Apex Seals.

Could be a number of things, the Gasket to the Engine. The Lines that run from the Pump to the Carb. It's an easy fix or so I'm told. I've replaced the Engine to Pump gasket, and the lines, going to see if that fixes it, if not. Then you'd have to rebuild the Oil Metering Pump.

To do that you need to order a kit from Mike Lowe. www.loweperformance.com Should be fairly easy. Hope that helps!

#1 Yea definantly the OMP on the leak. Not that difficult, do a search, somewhere there is a site that shows how to rebuild it...not to difficult. Do it soon or your radiator hose will get really weak and blow. The oil makes it soft and spongy.

#2 I don't know but I am having the same problem. I think mine is the spacer between the carb and the intake manifold. If you have done anything with this you might check it. Also there is some hose on the back of your intake check that for a leak. And if you think you need to rebuild the carb, do it. It is not that difficult, just make sure you mark everything and draw some diagrams yourself or you will have a b*tch of a time getting it back togeather correctly (I know...he he).

I would suggest if you don't need the rats nest for emissions to remove it just to simplify it and remove the possible vaccum leaks. Again another tutorial search.

Thanks for the reply guys! I was hoping to not have to do the carb rebuild but that looks like what I am going to have to do. I already got the pdf file for the rats nest removal so I guess I'll go that route when I put the carb back on.

The omp seems to be the consensus everywhere. I suppose I'll do it first if it is infact that easy.

When you sprayed carb cleaner, did the rpm pick up? If so you have an vacuum leak. when it dies and you have to restart, do you have to put your foot all the way down to the floor to get it restarted? Remember their is a hot start assist that has to be working. Are their any weird noisesc oming from the air cleaner area that sounds kind of like a honking sound? rx7doctor

When I sprayed the carb cleaner actually down the carb itself, yes the rpms picked up. And yea I have to have my foot to the floor to get it restarted too, and it sometimes won't start. Kinda like it's not getting enough fuel or something. As for the air cleaner, When the choke isn't on I hear like a loud whooshing noise coming from it.

I was looking for spraying around the carb, not in, testing for vacuum leak. If you have to put your foot to the floor there is too much fuel going in, meaing either needle seat is sticking or float level is off, check sight glass on front of carb after turning key on and letting it fill up before starting. When it is running, pull the lid off the air cleaner and listen for a very
loud annoying sound, you will know it if it is there. rx7doctor

Definitely no leaks because it never varied when spraying around the vacuum hoses. And no loud annoying sound either. So what does that mean??

Another good way to check for vacuum leaks is to put one end of a hose to your ear, then move the other end around the carb and vacuum lines. You will hear any leaks very clearly, it works just like a stethoscope. Still sounds like a vacuum leak of some type, but who knows? Good luck!

Well I ordered the gasket kit for my omp as I do know that is one problem but the carb is still up in the air. The best I can tell I don't have any vacuum leaks but the car still won't idle by itself. I have to keep the rpms up at 2k or the car dies. When the choke is on and the car is warming up I can see fuel being spit out on the butterfly side associated with the choke but it's not coming out good on one side. I think the carb rebuild is imenent but I am a little nervous about all of the little parts and getting it back together properly.

Bah, I say, if you don't have to worry about emissions up where you live. Then send it to Sterling or Carl and have your old Nikki Carberator Converted into a Sterling Carb... But you'd need a new Fuel Pump and Regulator...

Hmm...

Or you could just have one of them rebuild it to Stock Specs... But where's the fun in that?

Yea but I just wanna drive the sucker. The car sat for about 6 years and I just wanna enjoy driving it before the weather gets cold, ya know. After it does run properly I am going to have to get a new exhaust. I think the original stocker is on there. I can't count the leaks in it either. I'll probably do the rats nest removal while I have everything tore apart.
