Anyone do a compression test on their engines just as a part of maintenance? My old girl still runs great after 17yrs and 550hrs, but I was thinking I would do a compression test when I change the plugs out next week. It's never been done on this engine and I am just curious and have always wanted to do this.
For any of you who have done it, I have a couple of questions.
1. Just went and bought an inexpensive compression test kit at Harbor Freight.
2. I know you need to disable ignition, removing the coil wire seems to be the straight forward way, but won't flipping the lanyard kill switch do the same thing?
3. It's a carburetor, do I need to worry about the fuel system? On EFI you can open the throttle to prevent fuel from being delivered. On mine should I disconnect the fuel pump? Or does the fact that there are no spark plugs in the engine pretty much prevent fuel from getting pulled into the cylinders?
