Running on one rotor?!
Ack, leaving the house today my '83 started bogging horrendously. Turns out the motor is only running on the front (#1) rotor. The first thing I did was start yanking plug wires to determine this, and then yanking plugs and looking for spark (after determining it was the rear). The plugs have a very dark tan look to them, and the lower plug on the rear was had a nice smudge on it but this may have been due to riding around nonfunctioning. The only other test I've had time to do is to check the ohm's on the coils, and they check out ok. The car is carbuerated, so I presume that any fuel problem would affect both rotors, so to me this rules out the problem being fuel related. I'm still not %100 confident in the plug situation, though the car does have new wires and dist. cap etc etc. And from what I can tell this doesn't seem like a apex seal situation 'cause the rotor is completely kaput, not partially. Yanking the #2 rotor plug wires effects no change on the running of the motor. Anyone have a notion as to where I should poke at next?

Bad *** I don't think its that coaster valve thingy 'cause its just the rear rotor that is not firing -unless that valve specifically forks with the two rear throttle bodies on the carb. Ick.
For sure tomorrow I will be doing a real job of looking into the problem, just had no time tonight.
So yeah, I hope to gods the rear rotor housing seal didn't pop. There are no gaseous histrionics or anything, so I don't think its that. So wierd. WIERD I SAY.
This is what I get for buying a $1000 rx7.
Like a summer fling, it was fun for a month, but oh the regret!

You can just disconect the vacume hose to i, and plug it off. I had the same problem and this fixed it. the electrtical part is the middle yellow plug just follow the vacume lines from there.
