Ok I have an 82, and I'm trying to put an 83 nikki carb into it. My problem is that whenever I start the car up and press the pedal down it completly shuts the engine off. It revs up fine once I get it above 2000 grand. I 've also tryed riching the mixture out a bit, but it didn't do anything. There were two differences I noticed with the carb I pulled from it. There was an emissions system that I plugged, and some sort of sensor dead center in the middle of the carb on the passenger side. I point a pic below of the sensor. I think its this sensor what do I need to do with it?

 

im no expert but i had this problem and fixed it after some help from the guys on the forum. THis is what really helped me.

my acceleration pump had the middle check ball locked in by some debris and when i freed it up it doesent have this problem anymore. Hope i helped in some way.

 

Its called a richer solonoid valve. What does it do?

 

I'd blame the accelerator pump as well - leaking, clogged, jammed, or somehow not working.

The electronic bits, near as I can tell, don't do a whole heck of a lot except in the realm of cold starting.

most of it is junk. you would probably had better luck rebuilding your old nikki.

 

I did rebuild the carb, theres something wrong with it that I or a mechanic couldn't figure out. Its not the accell. pump the stream is good. I'm goin to try figuring out the wiring for that solonoid. Theres also a backfiring every once and awhile and the timeing is fine checked it.
