Timing chain
Im assuming there is a timing chain in a rotary.. there has to be!
correct me if I'm wrong![Smilie](https://www.rx7club.com/images/smilies/smile.gif)
I pulled out the ol' xenon and took a peek at my timing, not a big suprise its way off.. I cant twist the dizzy enough to get it even... timing chain is out a notch??
How do I access the timing chain :P

Im pretty sure that there is a different technique to using a timing light on a rotary since TDC is different, and the lack of a valvetrain, etc. Check in the archives on how to set your timing....

General Troubleshooting steps for rotary engines.
Step One never assume a rotary is anything like a piston engine. They have absolutely nothing in common aside from basic combustion.
Step Two read the archives avidly.
Step Three use the search.
Step Four then post for help.

No belt, no chain, just a distributor drive gear attached to the main e-shaft inside the front cover. It's about 3/4 of an inch thick, as big around as a coke can and if there was something wrong with it, you'd have a helluva lot more to worry about than that.
The Heynes and FSM (Factory Shop Manual) have information on adjusting the timing. IIRC for the leading you loosen a bolt and turn the distributor, and for trailing you loosen two screws and adjust the vaccum pot attached to the side of the dizzy.

If your dizzy has ever been taken out, it may be off by a notch. If you're *REALLY* sure you can't get it to time right by turning it, you'll have to take it out and put it back in, but I don't really know what you'd use as a procedure for that. Do some searching in the 1st gen section, there's some info there somewhere on it I just can't remember where.

Woo Hoo for no timing!
And my favorite way to waste time at autozone.
me-"Yeah, can I get a timing belt for a 82 Mazda Rx-7?"
clerk-"Yes, one moment while I look it up... Uh it says we are all out of stock. If you want to wait we might have them in a week."
Option 1: "What? Whats going to happen to the valves?!"
Option 2: "Rotary motors don't have timing belts, good day sir."
