Ryan is right about the manual saying 15% or under 90 psi engine need services, that why George statement surprise me a bit but he is not a young spring chicken and have done a few before and even if his tools are old as he is, they are like him build from a era of quality and perfection...( I'm such a..hole licker, you can pay me later George
)
Joke aside I really don't know what to think, for me 90psi is way lower then anything I work on before, these are very low compression engine so I walk in darkness territory here and I try to avoid stumbling on the carpet flowers...
For now my cranium Hamster need to be feed before he spin the wheel on high gear so i'll be back in a jiffy!
