Thanks for all who had suggestions. Reconfirmed all the ignition and fuel is ok. Started pulling plugs and was only able to get my compression tester into 4 of the eight holes; two on each head. I've only got between 30-50 psi. I guess it's good news that I didn't find any zero readings. Gonna run some marvel mystery oil in there, cycle it over the next couple nights then re test compression.
Any other thoughts?
Thanks,
Mike
