60-70 pounds is very low. Even at 6200 ft (i used to live at 9701 ft), your numbers should be higher than that. Even if you get it running, it won’t idle worth a crap. Look through the bypass covers and pull the cyl head. Look the thing over and see why you’re having such low numbers. I wouldn’t invest much into that one until you determine compression is no longer the issue.
