I just ran a compression check of my Spitty with 64M miles on it.
Got
#1 150Lbs
#2 145Lbs
#3 150Lbs
#4 140Lbs
Could not find spec in the manual does anyone know what it should be?

Thanks for the help.

Doesn't really matter what the actual numbers are; it's all about consistency across the cylinders, your numbers look just fine.

Numbers look good. I'd check mine but that means adjusting the valves and that sounds like work.
