Zach's set up is nice, but more than you need. Here is what I do:
- Furniture dolly from harbor freight ($15)
- Push button starter for engine from harbor freight ($12)
- Engine/starter adapter from me ($60 shipped to lower 48)
Put engine on dolly, connect up the fuel pump (power can be had from coil + side), connect up starter, push button.
To stop the engine, remove the coil B+ lead.
Less elegant than Zach's, but cheap and effective and leaves less crap to clutter your shop after you are done
