Throwing code p1650....

How do I check compression on these small smark plug holes just get a adapter and o ring correct...

Starts but is loud rumble noise that goes away after few seconds.

Paid 1800 for the ski and trailer.

Modesto mechanic put in new wear ring, ne impeller, new timing chain, new head gasket and bolts. Plus few other small things .was total of 1300 for the work no labor charge.

I can work on old 2 strokes but so far I'm stumped on these 4 strokes.... seems complicated. But I'm engine savvy just need to learn.

Ibr is down blocking jet pump

Haven't put I to water yet



Help me out any way u can please
