Can anyone tell me what the correct compression is for a Briggs and Stratton 10 HP engine should be? It is model 220707 and is mounted on a Case 110.
Thank you in advance.

An easy way test use flywheel kickback test turn engine by hand to compression stroke when get hard to turn turn a lose should fly backwards mean good compression. If engine setup over winter air moisture has swell carbon de carbon by removing cylinder Head clean piston and head lose carbon makes up down marks on cylinder walls. While head off check valve to see open and closing they stick open on Briggs. De-carbon make engine last you longer and starter want stop at compression stroke.

Overhead valve engine will take different game plan.

Thank you for the test info.
I'm trying to determine if it should be within the 120# or 150# range. I have my eye on a Case 110 so I would like to be sure the compression is alright.

The compression ratio of any Briggs and Stratton L head engine should be 6:1.
90 t0 120 on L head.

Overhead valve engine 8.5-to-1 they have higher compression 120 t0 150
