Compression check and spark plug?

Using Kroil eh?? I thought SeaFoam was preferred.... Starting to run short of Kroil these days and SeaFoam is available at NAPA.

Depends on what you are doing. for something rusted, or just stuck Kroil is my choice. for cleaning up a running engine, i use Seafoam in the gas.

So the Valves do make a big difference! About the same readings I got on the 50, after I set the valve lash. Probably not too wise for me to have waited until I was nearly finished with the rest of the Cub to do that, but sometimes luck trumps wisdom.

Yep John, that was what I was thinking... getting a bit tight on the Kroil supply and don't plan on needing a whole lot on the new tractor since I ain't gonna take it apart....

I would be happy with 90 across the board I mean not uptimal I suppose for cutting grass but if you get the seafoam in there and maybe it will rework the rings and help you out!
