Car stalls when choke is disengaged
I've read and searched, but didn't find any threads/posts with my exact issue.
I purchased a 1985 RX7 GS with 12,000 miles. It is all original. Recently the motor oil and filter were changed. I replaced the fuel filter and battery. Car has fresh fuel. The car has a manual choke ****.
Once I pull the choke know and start the car, the car runs.
After a few moments the choke **** automatically disengages. Then the engine dies.
The engine will only start when I pull the choke **** back out.
(Once warm, after re-starting the engine, I need to keep the accelerator depressed to keep the car running.)
I have a carburetor rebuild kit that I may attempt to perform, but I'd like to ask if there is anything else I should check as well.
Thanks for reading. Any input would be appreciated.

There's a guy named cfamilyfix who is pretty regular in the first gen section. I think maybe he's in Queens. Definitely NYC. He may be willing to help you out if you need it. A carb rebuild is easy. A lousy carb rebuild is also easy.
Read, read, read the 1st gen stickies and archives before you go. Sounds like your car is a gem. Please keep it as such.
All that said, it may just be as easy as shooting the straw through every orifice you can find. But I suspect there's a lot of unwholesomeness that developed in 30 years of little driving.

I removed the carb today and it took me about 2hrs.
I used different color nail polish to mark exactly where each vacuum hose came off of.
This is the rebuild kit I had ordered.
I'm going to bring the carb and kit to someone who has experience (unlike myself). I want to rebuild it but I need someone to look over my shoulder.
I'm not sure exactly who though.
I'll keep you posted.
Thanks for the input.

Like cookboy said you can try shooting carb cleaner thru everything and see if that works at the most you lose a couple hours if it doesnt . Then you know for sure you will have to tear everything down. A rebuild is fairly simple but you have to be careful not to lose the accelerator pump and nozzle check ball I know a lot of guys who have. Tear down and take picture as you go if your at all iffy about anything when you go to put it back together you'll have them for reference

I had a reputable specialist clean the carb for me and after I installed it, she ran fine. Now it doesn't.
The motor cranks but, will not start. Assuming the carb was flooded, I shut the choke, and, cranked the car while depressing the accelerator. White smoke emits from the exhaust, and smells like rotten eggs. After the car sputters it runs but sounds like its misfiring.
Im going to begin my search.
Im thinking the problem is ignition related.
Any input is appreciated.
TIA

I replaced the original plugs which were black and wet with fuel. I put a fresh set of plugs but haven't checked them yet.
I was told that because the car sat for a long period of time, the fuel system may still have residual contaminants getting into the carb.
If it starts I'm going to drive the car to try and run as much fresh fuel through the system by taking a long drive.

Car runs smooth. No more stalling. Topped it off with a fresh tank of gas. Now I have to address the uneasy feeling at speeds over 50mph. (I think the tires have flat spots after sitting for so long). Probably just get new tires.
The suspension sounds like new shocks and struts are next to be replaced.

Wow, your car looks very well kept Hipsiguy, I'm about 50 miles east of you on Long Island caught the RX-7 bug from my past also, 45k on the odometer, clean but not as clean as yours.

I've got the same problem with my SA, my solution: as soon when you're driving I push the **** back to its original place and no problem what's so ever (I'll never warm it up completely on choke)
