I've got an '83 GSL which was running great. All of a sudden one rotor quits firing. I've got spark and gas ok. Last night I did a compression check. The front rotor, the one that works, would get 60-65 on all three pulses. The back rotor, the one that's not working had 0, 0, 0. No compression at all! Did I blow two apex seals? Shouldn't I at least get compression from one face of the rotor? Thanks for any info.

Not necessarily, depends on what let go. You could try the ATF thing, but it sounds like it need a rebuild. sorry
