Fix Your Inaccurate Compression Tester

[Vintage Engine Repairs]

Did so for a mates tester and thought I’d share it here to document the process if anyone wants to know how:

Good work!

Sometimes my shrader valve gets sticky and reads low. When a good saw reads low I pull the shrader and wash it in gas and then the compression tester works right again. I've also used my air compressor as a reference point to check for inaccurate gauges. Just combine two male quick disconnects together as an adapter. You make great video's. I sometimes watch them. Thanks.
