Cub Compression Problem

Posted by Ted A Neis on April 27, 2005 at 14:07:08 from (64.242.150.67):

I have a 1949 Cub that is in real nice condition except it won't run. I have narrowed it down to compression I think?? I am at 8000ft altitude in Colorado and I realise that creates some issues. But I can't seem to get more than 30# compression. I also have a 1950 Cub and that one gets 50# & I have not done any work to it . The 49' had 0 -10 # when I got it, the valves were toast . I replaced the valves, reserfaced the seats and put in new rings and rod bearings I have the head torqued to 45# just like the book says. But I still can't get more than 30# the book says 120#, at my altitude I would be happy with 80#.I don't know what to do next unless the head is warped, I have heard that can be a problem with Cub's .
Any suggestions???? Any and all help is appreciated.
Ted
