Compression test

Postby kennystag » Sat Nov 07, 2015 5:10 pm

Hi All,
I put a Compression tester on my GP150 and it reads 90 PSI which I think is very good, anybody know what the PSI should be on a standard engine with about 6,000 km.
Cheers

It depends a little on how fast you can kick over the engine But I would expect 90psi to be ok. I've had higher readings.

Stick it in 2nd and push it to turn the engine over rather than kicking it. 120 psi is a healthy compression
