I used to use a socket on the crankshaft nut. This was too tedious and usually got nicked/scratched when the socket slipped. Some have made there own little switched to pump the starter. I tried doing the same but couldn't find the right switched I needed although I had handy the proverbial "pill bottle" and wires... So I gave up on this and went to NAPA and purchased a remote starter switch for $12. Couldn't believe how embarrasingly easy and fast it was to do the valve adjustment. The switch fits ergonomically perfect in the hand so that you can bump the starter by very small increments. One of the best investments I've ever made.
