cylinder leak down test???
hi
im currently in collage going to school for automotive and im doing engines, well i have an 87 t2 rx7 that will not idle due to an vaccume leak that i can't seem to find. On pistion engines we use something called a cylinder leakdown test to find out where its lousing compression / vaccume is this a safe test to use on a rotary engine just wondering??? thanks

no idle
there is not idle at all. it will start just to like jump to where its spost to idle @ and than stall shut off when its cold and than if i hold of foot on the gas for like 5mins and hold it ay 2000rpm's (let it worm up) it will idle @ 1krpms for like 2-3 minits than stall out agin. ive replaced all my vaccume lines with new silicone hosees and its make no differance what so ever. but if i adjust the throttle stop screw i can make the screw hold the throttle open at 2k rpms. is there anyother way to find a vaccume leak???

You can do a cylinder leakdown test, but it won't get you much of anything useful. I actually wouldn't expect the rotor chambers to hold much pressure for long, just due to the inefficiencies of sealing a rectangle.
