If you get tired of it let me know...I have had a good deal of experience with them .  The rotary is a cool engine but it doesnt do sitting around very well...The apex seals are easy to damage and are just as important as piston rings, a good size chunk of carbon that breaks free can wipe them out, and they leak coolant like a wasserboxer. The 12a is carbed and the carb will cause a TON of problems!  It has a electric fuel pump and a return type fuel system..it does have a drain plug on the gas tank, you may want to start there...We had a 84 in the shop a few months ago that sat for several years it was a 12a also and the fuel tank was totally full of crap, the fuel pump was dead and the filter was clogged.  After all that the carb needed to be rebuilt...Thats when we found that the carb kits for em are getting hard to find. You can find all the info you want on rx7club.com but careful what you post there,they kinda make the vw vortex look nice   You can always check out engineswap.com for the dangerous life...just don't bring it up on the rx7club

Great info Rick,   its been sitting,    the tank was dry and  I had a few gallons  of dirty lawnmower gas.  So I poured it in the tank.  I'm  going to see If I  can pump it though the  lines to  a pickel jar   and flush out what every is in there.

loose'nd the spark plugs  and poured Marvel mystery oil in it.  The engine spins  well  with no gas in it . I am delaying seeing if the apex seals are bad.   I read just hold you finger on a sparkplug hole  and if you get continuous pfss pfsst pfsst.  Your Golden.  Pfss  pfss nothing = bad   pfss nothing nothin = 2x bad ....

I see on Youtube folks rebuilding Wankels and it looks easier than a VW motor.

Bright side ,  No dents,  Good Seats and carpet, Ok tires
the Sound system is great and I sit in the seat,  crank up Lady Gaga with the moon roof off and make the head lights open and close to the beat.  Sc 
 
 

As the sun  set over the LaFayette triangle,  There was heard a mighty roar, as the tyranosaurous RX7 CAME TO LIFE!  A noxious cloud of blue and white smoke fouled the air. Mosquito's fell from the sky.  Then all was quite as the RX would not idle and conked out.    Hot Diggitty ding dangs! We gots a runner! SC

Unless, of course, the running briefly period was followed by the engine turning over really fast....... 

There should be a tuner on the dash to solve problem #2.    

The Carb is bigger than the engine

i thought vw used alot of vaccum lines until i worked on japanese cars

88 Honda Accord LX.... I have never seen more vacuum lines on a carb. car before or since.   

well its running,  brakes are working a little.  the clutch will work but if you go in reverse it loses pressure and you can't get it out of reverse so it conks out.  So its A-OK.   Except for this leaking oil problem,  its a drip a second when its running.  When the oil gets low a red light flashes and a chimes starts ringing.  Not Cool.

This picture is from under the driver door.  The higher big bolt is the tranny filler. The oil seems to come out of the lower bolt that holds the tranny to the engine.
I'm Hoping Rick has a idea what it is before do something rash.  SC

I as looking at my picture above.  It looks like the engine oil pan goes under the bell housing. Which is wierd. Hmmmm  SC
