Anyone know about really hard starting after the rotary is warmed up? Mine sometimes takes 10-15 attempts to finally start. One chamber also is not firing for about 15-20 seconds, then runs fine. Already changed the plugs.

How about the plug wires?

Coils, etc.

Compression Test? My first motor was like that (had low compression).

Yeah, I would have to say low compression.

sounds like low compression. Mine did the same thing :0

Thanks for the ideas. It turns out that low compression is the problem, unfortunately. Its rebuild time.https://www.nopistons.com/forums/pub...1047683664.gif The new question is what are the best parts for a reliable and dependable motor? I'm not looking for gobs of horsepower, just more worry-free daily driving. Thanks again.

Stock seals work best imo.

the only apex seals i haven't broken at this point at the stockers and RA's. I normally use all stock seals everywhere else in the engine.
