holy crap did you forget a 1 in front of the 40 and 70. how many miles are on it? i would try it again and maybee add some oil to the 1 and 3 cyliders. your rings are probably shot.

you cant really 'fail' a compression test, but yea, those numbers suck. Did you remember to keep the throttle at full open while testing each cylinder?

:hitit: WITH A SLEDGEHAMMER!!! Those numbers do suck. Try the wet test like suggested. Overall though with those bad of numbers you might as well rebuild it.

Id say it needs some attention hehe - Hard to tell more precisely what it is with such an extreme diffrence between cylinders.

*edit* thought you had a KA*
