Default Re: #1 cylinder has 36psi compression

I don't think I would do any more testing until I put some serious run time on it.Under a load,not just sitting in the yard.Having worked on old tractors and equipment all my life it is something I have seen a lot of.People will put oil in the cylinders of something that is going to sit,then the winter turns into years.As the Kendall oil rep put it to me,that oil turns into asphalt in the piston rings.It will wash with run time.I have a Ferguson-Ford here that the owner tried to do a leakdown test on.It would hold nothing.After about 40 hours of mowing it runs good,and will hold at least some pressure.
