I haven't looked yet but is there enough room under the frame to adjust the intake vavle with the engine stil installed? I know the tank will have to come off.

I have a compression tester with three different spark plug sizes just not the size of the plug my 185s has, what do you guys use to test your compression?

 

You can adjust the valves with engine in frame
But the sear and fuel tank must be removed

The compression tester I found one at Pep Boys with the correct size addapter
Or if you can find a rubber tip tester would be better but they are getting hard to find
Good luck
