The manual says" We don't publish compression numbers since it requires special equipment "
It goes on to say both cyls should be w/25% of each other and gives 2 examples of 60 and 70 PSI.

ANYBODY Know a good number for these twins? I know a KAW 14 JD engine is over 130-I think.
Mine in the Gravely-HOT after 30 min of mowing is 93/95 and this is a 15 year old engine.???

So what the manual is saying is that B & S doesn't have the "special" equipment to check compression, so they don't know what their engines should be??
