Compression Test this weekend

Hi all,
Is this all i need to do a compression test on a TPI?

Connect Battery Charger- for equal charge over each crank
Disable fuel& Spark
Pull out all spark plugs.
4-5 Cranks
Anything 130PSI or lower bad
All should be within 10% of each other.

Re: Compression Test this weekend

Open the throttle all the way.
If its relatively stock, probably will be in the 170-185 range.
