ignition timing
#4
Stock base ignition timing for the later model(after 1984)22R is 0°(which should be stated on the sticker under the hood). As in, no degrees BTDC or ATDC. That's only with the vacuum advance disabled, meaning both hoses on the distributor disconnected and plugged. With the vacuum advance operational, both hoses reconnected, it should be ~13° BTDC. If it isn't around 13° BTDC, or is around 8° BTDC, pinch the hose between the three way connector and the HAC(High Altitude Compensation)valve. If that doesn't move the timing to ~13° BTDC then the HAC valve may be faulty.

Yeah, I couldn't tell ya on that. But, there should be some kind of vacuum advance on it. Or is that different too? I dunno. It's pretty hard finding good info on that 22R. That was the best I could come up with anyway. Hope it helped a little.
If not, then keep askin' around, somebody might have something better.
Good luck!
