Has anyone checked the compression on a stock spark? If so, what are they?

Just curious, but are you planning to do any modificaitions to the engine? Like a turbo kit or something?

No, mine ingested water and wanted some comps to see if it's where it needs to be.

compression is 11 to 1 so 14.7 * 11 so should be in the 160psi range
I will do a test next time
