Rusty,
Experience, mine, shows that it is a good idea to have a fresh set of plugs
available.  It has been amazing how easy it is to foul them when the mixture
is too rich or there is too much 2cycle oil coming through.  This has been
no problem after getting my wiring and programming done right..:-)  I went
through 4-5 sets of plugs in the early going.
To echo Lynn:  Another great thrill is to have that little hummer smoothly
idling with the prop on, and all the initial mixtures set, EGTs balanced,
temps in the green, timing right, and just waiting for your command for "Max
Power!"

No thrill like the first start. Good luck.
