need help
I JUST HAD MY 13B NON TURBO REBUILT. NEW SPARK PLUGS &INJECTORS CLEANED. I HAVE NOT DRIVEN THE CAR BUT HAD IT STARTED FOR APP 10 HOURS. EVERY TIME I STOP THE ENGINE IT HAS TROUBLE STARTING EVEN WITH A FUEL CUT OFF SWITCH. COMPRESSION ON BOTH ROTORSIS APP 75PSI. WHEN IT DOES START IT RUNS GREAT.

The below is taken from a post by Kevin on rebuilt rotaries. As you will see, you'll need to get some miles on it to build compression.
This is not a rebuild 350v8 piston engine, and it is not a toyota camry. It is a turbo rotary. Theyre vastly different. The way they work is vastly different, and the way they respond to rebuilds/fresh installations is vastly different. You can NOT expect a fresh rebuild to run well; it has low (less than new spec) compression, often less than the old one you removed. The reason for the long, specific breakin period is to allow compresssion to raise up to a normal level befor eyou beat the **** out of the engine.
The best thing you can do now is set the idle up so it'll run, and go on a good road trip, or at least drive it all you can, normally, staying out of boost (above atmospheric) and below 4-4.5k. Hell, even letting it idle in the driveway is better for it than not running at all.
Dont even bother revving it out or trying to boost it until breakin is done, cause a) you can do more damage than good, and b) the rebuild is still weak, and wont give you much power anyway...
How you treat your rebuilt rotary for the first 2000 miles is directly proportional to how well it will run for the next 100000
