Planning to do a compression test on an NSF18B2 with electric start. I've watched a lot of videos and read some forum posts and it seems like the steps are:
1. make sure battery is fully charged
2. run the motor till its warm and then run gas out
3. pull off the kill switch lanyard
4. remove both spark plugs
5. put compression tester into spark plug hole
6. press electric start button and get reading on compression tester
7. repeat 5 and 6 for other spark plug hole
Is this correct?
Also, I'm not clear on whether I need to do something with the spark plug wires. I've read a lot of stuff about sparks jumping and damaging wiring and don't want that to happen.
