I have an 82 RX7, after I run the car the engine always gets flooded. The car has the 12A engine and the original carburator. I usually have to pull out the plugs, dry them up, shut the fuel pump and crank the engine for a few seconds to unflood it. Once I do that, I usually have to push start it with another car. Once it fires up it runs great.

A few weeks ago at a C&C I was talking to some guy who had a really nice first gen. I told him my problem and he said that I should replace the Nikkei carburator and that my problems of flooding should be solved.
Would any of you out there agree with this suggestion??

Thank you.

 

Have you done a compression test? Have you checked for vacuum leaks? You should be able to disable the fuel pump and start the car with just the gas in the bowls after a drive or with a cold engine.

 

Thank you for your advice, I will try and do that as soon as I can.

Regards

 

To add to the above, when the engine is shut off after you have run it and let it sit for a normal amount of time that produces the flooding, inspect the front sight glass on the carburetor and see where the fuel level is. It should remain about halfway up the sight glass. If it's empty or very low, then the gas from the float bowls is leaking into the engine.

 

Hey, I appreciate you following up. I keep the car in a warehouse. I fired the car last Thursday and I shut down the fuel pump and let the car run until it ran out of fuel, which took about three minutes. So tomorrow I plan on turning on the fuel pump for a few seconds before trying firing it up.
I'll let you know the outcome.

Thanks.
