Which compression tester gauge?

The smoke sounds normal to me. they all seem to do it at first. As long as its not doing it all the time I wouldn\'t worry too much about it. The idle though could be one of many things. Vac leak, TPS, Thremo wax thingy etc etc.

Small amount of blue and even white is normal on startup - blue=oil and white is probably fuel - but if it smells sweet then it could be coolant - but it\'s most likely fuel - they are gassy when they start.

Did a compression test today which i think went ok, got 3 strong needle bounces on each rotor. Rear was reaching around 100psi, front a little lower, but still well into the 90s. I took some videos so you can see.

TPS adjustment made a slight difference, but I\'ve yet to try a proper cold start. Still idles quite low (500rpm).

Now, when i drop the clutch pedal, the revs used to dive down to almost 0 and come up again. Now, it drops to about 900rpm does a little bounce and then drops to 500.

Took the car out for a drive this evening to see how it starts from cold. Seemed much happier. Think the tps adjustment has made the idle seem a bit more consistent, if a little low.

Though i think that might be down to an exhaust leak. The fumes i smell in the cabin on start up and after boosting i think are exhaust fumes. So think that\'s gonna be the next place to look.

Also, noticed my front spark plug was covered in carbon deposits, which i think means too much fuel? probably normal for a rotary i guess! :p
