Is it low compression?
My '88 engine blew blew with 95,000. I sent my engine to Atkins Rotary in Washington state with the "good" rotor #1 having avg 8.0 kgcm2. They rebuilt it & performed a stage 2 porting to improve horsepower. The engine left their shop with a bench test compression of avg 9.3 kgcm2. After re-installing the engine, the care wouldn't start. 2 different RX-7 techs in my area (considered to be the best rotary techs at their dealerships) could not get the car started. After researching further, I replaced the air flow meter and the car started. However, the tech still could not get the car started & stay running. Tested to be fine was the crank angle sensor. This tech tested the compression & it tested @ avg 6.3kgcm2.
Engine symptoms now: it cranks fast (normal) sometimes & slow other times. Starter tested good. It floods easily on start up preventing starting (I have to crimp a fuel supply line to get it started). Once running, the car seems very sluggish (low rmps - lower than my old engine without porting), stalls at low rpms without a/c on.
