Trying to start a 77. Motor locked. Where to begin?
#1
I just bought a 77 rx-4. It has sat for about 15 years. The engine wont rotate but I hear thats normal. The oil looks good. I check the plugs and they look good, the carb is gummy but no rust and butterflys are clean (like new). What do I need to do to get it unlocked? Ive never worked on a rotary so im lost on this. Thanks for any help!!

why dont they just make the side seals out of hardened aluminum? it wont rust, and its hard, so it wont break easily.
how do they wear?

This I know . Aluminum is way too soft of a metal and melts at a low temp. You wouldnt go very far before needing a rebuild. I let the engine soak in ATF today. Still nothing... Maybe tomorrow. How long should this take? Is there anything else I can do?
it depends on how bad it is. if its just carbon stuck, maybe 24hours, if its been parked for 20years cause it blew a coolant seal then its never gonna break loose.
one trick is to pull the round rubber plug off the bottom of the trans, and use a big giant prybar to turn the engine via the flywheel teeth. not sure if a 77 would have that plug though
