JUst finished putting the good running carb on the 84 GLS, hooked everything up, new Optima battery, turned key to let fuel go to carb, tried to start and engine just turned butdid not fire, smelled fuel got out of car to see the carb completely full of gas all the way to the top. Turned key off let the car sit to let fuel go down, unhooked battery, pulled plugs and resistors off, when out about and hour later, hooked up battery turned key on and carb again ran over with gas. What is up, I give up, this is beyond my limited mechanical knowledge. If i cannot fix it then I am going to sell it due to my left leg injury in Afghan becoming worse and unable to press clutch.

Dude I had the same problem, and I did finally figure it out, when I rebuilt my carb, i didnt adjust the float bowl right, so it continued to dump massive amounts of gas into the carb, and second I made the mistake of cleaning out my fuel screws, even if it was just a minor amount, microns of an inch can screw the whole thing up. After much anger and disgust I finally broke down, and finalized the float bowl adjustments, and ordered new fuel needles, and BOOM worked perfectly! I hope this helps, another option, tear out the old intake and carb and throw a weber or a holley on it!

 

oh yeah if you do sell , let me know where your at, and how much you want!

 

I am in Alexandria,LA, the car is awesome shape, just needs a few touch ups and the paint needs refreshen. I have an 85 with a Supercharger that I just gave my brother because of my injuries. I have an automatic 88 Quest with 52k original that i am upgrading and my 89 Starion that is in storage it has 20k original on it. I have my 75 MG Midget that I am trying to find a good used top or will break down an buy a new one for $200. If Interested I will send you pics tomorrow. I paid $2500 for it last Dec and I will sell it for $1500, has louvers that are not installed, 3 carbs, This car does not need much to make it a show car. I ws looking at puttng the same Camden supercharger that the 85 has or a turbo. LAter,Gary

 

first to try is sometimes the floats actually get stuck if sittin awhile. take the end of a screw driver, turn the car on, watch the fuel come up, bang on the top of the carb a few times to see if you can loosen the floats. easy fix if it works. done it plenty of times.

 

did you turn the engine over with the plugs removed to get rid of all the gas in the motor?

flooding is the most common reason rotaries won't start. and if you do flood it, you can't just let it sit a day or so and start it again like you could with a piston engine. you HAVE unflood a rotary if it was flooded....EVER

 

Thanks for the info but i had pulled the plugs and turned the motor. I know about flooded rotaties and how to unflood them both ways as listed at rx7.com. The carb is filling up with fuel and i guess the floats are stuck open. I just got this carb from being rebuilt. I have my original and another one that was sent to me from a running car and will try again Wed because of rain expected here on Mon/Tues. I probably am going to sell it though. Thanks,Gary

 

Was the fuel pump ever changed to a carb style one? If you still have the SE pump you have way more pressure than the carb can handle and it will flood like crazy.

very interested, i live in des allemands, louisiana. would love to see pics.

 

Good point about that fuel pump. If you have an fuel injection fuel pump on there, you'll need a pressure regulator to keep from drowning the carb.

 

It is not the pump or ignition, car has been drive by me since I acquired it last Dec 04, just flooded alot and I would unflood it and it would be good for several months until it did it again. Car had set for about a year before I got it only being started occassionaly so carb could have been bad and then when my car was broken into see attached thread, wires were cut. I just got a rebuilt carb in and put it on yesterday and the gas flooded the carb so that is where I am at. All work orignally was done at Rotary performance, the 17yo I got it from thought it was a Se but VIN showed a GSL but when I called Rotary Performance the Uncle who had car had everything done to car to make it look like SE except wapping motor. Will post pics this evening. Thanks,Gary

 

Does the vent solenoid work?

 

There's no reason to get so frustrated that you need to sell it. Just fix the problem. There's not much it can be.

 

Here are some pics of car, I have the rear bumper piece in my storage bldg. Will try to get pics of it later. It was barely on car when I got it so I removed it so it would not fall off and be ruined. Nephew who was left the car tried to use some sort of glue but did not hold.

 

You wanna just get rid of that sweet ride, I will drive up there and help you out, you cant sell it!!

 

It is raining now and tomorrow too so Wed I will try to work on it again. Body has 175k, will try to get hold of nephew of the man who had the car and see if motor was rebuilt when all the upgrades was added. Has tokico blues adjustable shocks, front/rear swaybars.

 

This is going to be a small problem, start with float adjustment.

By the way Tokico blues aren't adjustable, if they have the adjustable **** on top they are Illuminas, much better than blues.

 

Sorry I meant to write Illuminas but had my 5yo daughter on my lap singing Blues Clues when typing. I know nothing about doing the carb, bought this one from a guy who had it just rebuilt and was on his 84 GLS running good until he wrecked it last week.

 

Your fuel pump may be putting out more pressure than his was, try a Holley fuel pressure regulator, it's a good upgrade with a Carter fuel pump, available from Summit Racing

 

dude i would lveo to buy this from you, my car is about 5 years and like over 5000 dollars away fomr running, so i would love to come pick your car up. let me know if you still want to sell it, that thing is clean, any engine shots?

 

Check to make sure all your wires are hooked up. There is something called a vent solenoid on the "front" side of the carb near the top (side with the small barrels). Its a cylinder style thing with 1 wire coming out of it. MAKE SURE this is hooked up. I had this exact problem and it turned out I just forgot to hook up this one little wire. What it does is equalize the pressure in the fuel bowls as they fill and empty. If this isn't hooked up, the pressure would get to be enough in the top of the fuel bowl that it will force fuel out through the jets at a rate enough to almost flood out the engine while running, if you can even manage to get it running in the first place.

 

sounds like a stuck or open needle,the float won't shut it if the seat has got crud in it and the needle will stay up and let fuel in ,the float can't make the needle sit in its seat beacuse if the crud..sometimes its just a simple as giving the bowl a tap with somethin to dislodge the piece of crud..or takin the carb and rebuilding it..try the simple way (tap it ) ..hope it's just a small thing..you raelly do have a nice car and it would be a shame to have you give up over such a simple fix..anything can be fixed..just as long as you have the motivation and patience ..plenty of guys to help you get through the fix here,..GOOD LUCK..

 

My first inclination as others have stated would be to check the float level or fuel pressure. Even a half psi difference in fuel pressure can make or break the setup. You need to fix the problem instead of giving up when it doesn't immediately work. You'll never have good running car with ths logic. I've gotten frustrated and wanted to just give up sometimes. It's usually something easy and stupid though and almost never worth the stress I go through to fix it. Tell us exactly what carb you have, what fuel pump and regulator you have and what fuel pressure you are running. There are some smart carb people here. Someone can probably tell you how to make it work decently.
