Do the compression test first, throttle wide open.
Re TDC, the marks are on the trigger wheel(ignition) under the cam chain cover(right side).
You can also rotate the engine (for the particular cylinder your checking) using the starter.
As you feel compression build on THAT CYLINDER, poke a screw driver down and touch
the top of the piston till it comes up fully. Now, your at TDC on the compression stroke.
You can also lock up the crank with a socket and breaker bar reaching thru the CENTER cover
located on the cam shaft cover.
Re spark, you can just ground out the spark plug wire to the engine / frame..
