I only used the B&S leak down tool (P#19545) with the piston locked at TDC. It indicated low leakage of around 20%.
For a picture of the tool, see:
https://tinytach.com/specialty-engine-toolsI'm away until early next week, so will put the compression gauge on next week and let you know.
It's a shame such a new motor is so useless. I wish it was still under warranty as the valve clearances were way off spec. I wonder what else is wrong!
I too have found the 12 cu inch Inteks wear oval rapidly and don't last like the old Japanese Vanguard engines. I have a 2007 127332 CP550 water pump with 4,000 hours on the meter due to be bored out to 20 thou whereas a 1998 Mitsubishi Vanguard has done nearly 30,000 hours on a water transfer pump and when I de-coked it two years ago, the cross hatch in the bore was still clearly visible! Both motors are owned by the same owner and also receive scheduled maintenance.
