83rx-7

Hi 1st gen rotorheads, have 2 small problems. 1. My LE 83 runs great and all that, however when I started in the morning or when it has been seating for a long time especially whent the weather is cold (gets pretty cold in KS) it idles for a few minutes but then it starts fading out until it finally dies when I let this happen it gives me a hard time to trying to start it again. However once is warmed up it runs great. I am running a 12A with 44MM Mikuni Sidedraft Carb and racing beat manifold and header. 2. I am trying to install power windows, I have all the hardware, however I don't know where to wire it too. Can anyone help with any of this 2 small problems. Thanks to all of you in advance and keep on RX-7ing.

Do you have a choke hooked to it? IIRC, theres a pseudo choke on the Mikunis which will help alot with cold starting.

Ummm, I believe the wiring harnesses are the same so it should plug into the factory harness. Is this factory power windows from another car or an aftermarket setup?

The choke is hooked to it, and it still does it with the choke on. Yeah the window regulators and switch are from another 7.

is it an automatic choke? or a manual choke?

could be choke setting if its automatic...

ever let it idle that long after its warm...maybe its not moving enough fuel at idle...or something <grabs at straws>

My guess would really be a choke problem. Cuz I used mine here in Canada dring the winter ( I know *slaps himself upside the head*) and it NNEEVVEERR would have started without a choke ... or at least without a choke OR me keeping my foot on the gas till she gets warmed up. And the fact that you ave a hard time starting it afterword is normal too. My idea on that is that you almost flooded it. Cuz I've learned ()the hard way, in montrea 2 hours away from home !) that in cold weather, if you start it and don't let it heat up, i.e. park your car on the other side of the road then shut it off right away, it floods out BADLY lol .. I figure yours ALMOST floods so you'd have a hard time starting it with a bit too much gas in like that.

Correct me if I'm wrong ?

On the account of sounding dumb, how do I know the difference between auto choke and manual choke?

By the way here is my site if rotorheads want to see more pics of my 7.

The first gens came with a choke that was a cross between a manual and an automatic.
You set the choke by hand (i.e. manual), but it kicks itself off automatically when the temps reach operating temp, ala an automatic choke. It works off of a magnet.
My car always had a problem right after the choke would kick off until I ran it out a little bit. It would try and stall. Sounds like the same problem you have. I just learned to live with it. A tune up and maybe richening the carb a little might help.

Actually that is what I have been doing (living with it) I mean is really no big deal is just annoying. The problem with my choke is that I set it and it takes forever to disengage, is this normal?

Rx7carl

Well the colder it is outside, the longer it'll take for the car to reach normal operating temp, which makes it take longer for the choke to drop off. Even here in FL, mine wont drop off in the winter for 20-30 minutes.

Well I guess that explains it. It gets pretty darn cold here is KS. Thanks for the input.
