This is actually to be expected to a certain extent with these cars, since they are designed to inject a small amount of oil into the combustion chamber to cool and lubricate the seals. When the engine is shut off the last bit of this injected oil does not get burned off, and just sits in the combustion chamber. It is then burned at startup along with freshly injected oil, giving a "double dose" for a second or two. I would be more concerned if, after sitting a while, the motor DIDN'T produce a little blue smoke. Now if it looks like you're fogging for mosquitoes, I'd say your rebuild wasn't a complete success, but as long as the smoking stops within a few seconds, I'd say it's OK. I totally agree with the above answer... I've owned 2 RX7's and the both blew blue smoke at start up. ZOOM ZOOM!!!!!!!!!!

Ditto. I own one with 63,000 miles on it and it does it too.
my 84 rx7 has 160,000 miles and does it aswell and she still runs stong
these motors, 12A and the 13B, have an oil metering pump that injects oil into the rotor housings every time you use the gas pedal. so the more that you pump the gas the more oil that is injected into the housings. its to help all the seals and apex seals to live in the harsh temps in a rotor motor.(long time rotary driver and racer) thanks

Could the distributor be the problem when the engine quits runnig every 15 seconds on a 3o2 efi engine?
If you are saying the engine starts and runs for 15 seconds and dies and then starts again for another 15 seconds and dies . . . the distributor seems to be doing its job. You might want to check if there is a fuel restriction somewhere (filter or pump).

Why does a Briggs and Stratton 6.75 hp lawn mower engine stop after 2-3 seconds after it starts?
if it starts and runs for just a few seconds then dies it is generally a carburetor issue. clean or replace the carb and that should solve your issue.

If it starts and stops within seconds and after a few minutes starts again only to stop again, the fuel filter is probably clogged,

Why is your BMW 323I 2000 shakes when it starts cold for 20 seconds then the choke kicks in and the engine settles?
It is the VANOS working in conjunction with the cold start injector... once your engine reaches that proper temp, the "shaking" goes away.
