help!!
Hi. Excuse my bad language(norweegian)
I have a 88" rx-7 13B TurboII, since i got it it has been hard to start, espesially when it`s warm. But a few days ago it warned me about low oil level in the middle of a hard right turn. I stopped right away and checked, it was at the minimum. drove home and parked, the next morning i refilled oil. But when i tried to start i allmost didnt got it running, when it finnally started it was almost no power in the engine, and it comes a "little" blue smoke out of the exchaust. bought the car about two weeks ago. i never pushed it very hard shifted no later than the rpm warning(except 1 time i had almost 8K rpm) does anyone had some similar problem? really need my my engine running well again
It should be said that i've never worked with a rotor engine before.

Welcome to the forum.
The trinity of internal combustion is: fuel (just enough), spark (at the right time), and compression.
Where an older rotary has trouble is compression.
The oil film in the chambers is a critical part of the compression seal. A flooding event can wash out the oil film.
Another important factor is cranking speed. A freshly charged battery with shinny bright metal-to-metal connectionsis neccessary.
The spark rarely gives trouble. Just clean & check the plugs & wires.
Your low power condition could simply be a mis-fire on one rotor. The spark plugs will tell you.
Also you should do a compression test to verify the condition of the motor.
The FAQ information stickied at the top of this forum has much good information.
Also there is a link to my on-line copy of all the factory service manuals in my sig.

small amounts of oil gets injected into the engine for lubrication, and burnt off... it's a rotory thing. i would do the 60k tune up if you want your car running well. and always let the engine warm up before shutting it off. so no short distance drive's or moving your car so a buddy can leave...
well, good luck and congrats on the TII

Sounds to me like he's having some minor flooding issues.
I would suggest trying a fuel pump switch temporarily. Install one and then during a hot start, leave the switch off while you crank the car for a second, then flip it on and see if it fires. If this fixes the hot start problem, you know its just being slightly flooded and that fuel is washing the oil film off the seals causing lower compression, and in turn......a difficult start when its warm.

With proper compression and non leaking injectors there is no need to worry about starting cold and turning off cold.

Yeah, actually more of a compression issue. Yes you occasionally saw that problem when new, but most of the time it was when the car had less than 90 psi compression, that if start the car and then turn it off before it is up to temp, they tend to flood.

Thanks Mark, I figured it was something along those lines. I've heard many new owners around here say "I heard from xxxx that you shouldn't start it and shut if off when before its warm" and I could never think of any reason why except something wear or age related.

shyt i am having the same problems, im in cali right now and we are having record high temps at leat 110 everyday!!! but i also have a question the bat he had on the car is huge and when i try to start the car i think i can smell the starter..!! i have cleaned the termanals and made sure the car is the flooded by pulling that 40 amp plug, and it just seems soo weak when it trys to start like him i have never worked on a rotary before either but i have worked on plenty of engines..! so should i go and check the spark plugs..? and i thought that is would be fuel since it was like on E big time so i went and put some fuel in it and still NOTHING! the only problem that is throwing me for a loop is that it starts sometimes...it is crazy this car is already seeming to be like my 240 a problem child>!! any suggestions would be greatly appreciated
