I'm having troble with my friends 84 rx-7 the fuel pump is bad but also i need help ajusting the carb to spec to pass smog. also can anyone help me get this car to pass smog it has new exhaust(everything from block to tail) and we're going to get a k&n air filter also the moter was replaced 2,200 miles ago b4 we got it it sat for 3 years but like an rx7 started right up (off carb cleaner because fuel pump is broken) i just want to get it to pass smog

 

This thread needs to be moved to the 1st gen section as this subforum is about engine failures and causes.



If you've got the ability to move it, go for it. Otherwise, I suggest reposting it in the 1st gen section.



Thanks,

basically on the carb there is just an idle mixture adjustment. if you've got new cats, its usually cleanest a little rich of best idle.



also the air pump and air control valve need to work.

 

Move to Ohio. No emissions controls.



Anyways, replace the fuel pump. Then see how things burn out the back end. You might be pretty right on as far as emissions goes.

 

hy if u want look me up i have a brand new k and n maybe 1000 miles

i also

have any smog stuff u may need i went with a delloroto set up so i dont need it

 

Huh?

I don't need emissions controls. Ohio no longer has any smog/emissions regulations.

 

Start with a complete tune-up, then work systematically to find the problem.

I'm a newbie to rotaries, but when I bought a Random Technology cat for my old Jeep, the guy grilled me about how well I had the mixture set, and that I made sure it would not run too rich. The excess gas and heat will burn out a cat in no time. I know zilch about carbs, but the richness factor may be something to keep in mind



Of course here in Cali everything is about smog.



Good luck.
