Saved a rotary ( not sure what it is)
Hey guys my buddy got 3 rotary’s from a airplane mechanic who was gonna use them and ended up giving 2 out of 3 to me one of them has 2 distributors on it and the other one says it’s a 13b but has a carburetor on it the 13b still spins over but I don’t know if it builds compression the one with 2 distributors was completely frozen

On the top of the duel dizzy, if it's a 12A it will say. I had a complete 12A dual dizzy engine I sold a couple of years ago. They are rare, but extremely hard if not impossible to find many of the parts to rebuild. I think I still have one or two rebuild kits and a few other parts.

No problem Brother. The twin distributor 12A motors also have the starter on the top of the engine that connects to the tranny bell housing if my memory is correct. The 13B motors that were in existence prior to the RX7 being produced came out of RX-4's, RX-5, Rotary Pickups and some RX3 wagons (though my memory is sketchy on the RX3 wagons). GL!

Exhaust Manifold Leak
love the italic font on these rotor housings. our RX-3 runs them with PP for years of racing now. they start to develop hairline cracks around the leading plug holes. if these housings are not flaking chrome and you want to separate yourself from them let me know =)
