Hi i have a 1979 Mazda RX-7 that has been sitting in a garage for a while and now will not start. I was able to start it a couple of days ago but only for about 30 seconds. I know that shutting a rotary engine after only a short period of time will flood the engine. Now a couple days after it started it will now not start. I have replaced the spark plugs and the leading and trailing ignition condensers and i have tested and am getting fire from all of the spark plugs. I have tried taking all of the spark plugs out and cranked the engine for about 15 to 20 seconds to try and clear out all the nasty gas and oil. I also have put in new gas with a little sea foam in it. I tried pouring a small amount of Automatic Transmission Fluid in the carborator and trying to crank it up to unflood the engine and get it started. Im not sure what else i can do to force the engine to start. I believe that it has pretty good compression and it is definetly getting spark off of the plugs. The Fuel pump seems to be running fine because i can hear it and i see gas pour into the carborator. Any help is appreciated!

Thank you very much!
God Bless!

'79's have lousy gas tanks that "peel off" inside. The particles "gum up" your gas filters as quick as you replace them. Sea Foam isn't going to help nor is fresh gas. The gas tank needs to be taken off the car and taken to someone to "steam/boil/or otherwise clean it out. I've talked with several '79 owners and that's the only solution.

Once reinstalled you may want to consider installing another gas line filter in the engine compartment near the firewall. That give extra protection so that none of the small particles get into the engine, because they will sure mess up your engine but good !

 

One other idea if you're getting gasoline to the carb. Make sure the carb floats aren't "sticking". Sometimes "tapping" on the side of the carb will free them. Or they're not too expensive to replace.

Good luck.

 

Use the Seafoam to get her started rather than ATF. Seafoam (pour a couple caps full down the carby) will work much better, faster, clean your spark plugs off (where ATF will foul them), won't hurt your seals (as ATF may), cleans the carbon off the apex seals, and makes you look sexier to the opposite sex. Nothing better for getting a flooded rotary going.

How are the points? Have you checked them yet?

Lots of info on these carbs can be found at www.sterlingmetalworks.com

Good luck!
