Fresh rebuild low compression... maybe
 

Long post grab a beer and strap in... So I did a rebuild on a TII I picked up along with some other changes to the car. During the rebuild my parts got moved and the side seals got mixed up, I did set them in the rotors where they fit best and they all ended up with clearance withing spec(cheap crappy feeler gauge fwiw). The engine got all new springs, new oem apex seals, new atkins gaskets, only parts I reused are the side seals, oil control rings, and corner seals(with new plugs and FD springs) and of course the irons, housings, rotors, ect all in decent shape/within mazda spec but not perfect.

Now, she fired up pretty easily first start but ran like crap until I figured out the CAS was 180* off, fixed that it ran pretty good at least enough for me to get it out the shop and tak eit around the block. fast forward a bit, car now has a ok basemap for no boost driving while breaking the motor in but is having trouble starting (cold and hot). To me it sounds like crap and revs kinda slow, I did a compression test but all I have tester wise Is a cheapo tester that doesn't have the little valve anymore with a 2f hose. My bump numbers are nice and even 85,85,86, front rotor but 66,67,67 on the rear rotor cranking speed right at 205rpm (adaptroninc ecu numbers).

My question is will the compression get better after the motor is broken in? I may have 100 miles on it max, used rotor housings in pretty good shape but new apex seals. Should I just continue to run it and go ahead and actually have it tuned (I can make it run but that's about it I no tooner lol), or should I pull it down and swap out the side seals, rotor housings, and have the irons lapped?
