Kyle,

Countdown to liftoff. Your carburetor idle screw adjustment is OK. The shade tree standard is usually one and a half turn out.

I think I would try to start it just as if it were sitting in the driveway after a nights rest.

If it backfires and flames, just hit the starter again and suck the mess into the engine...it will extinguish it.

If absolutely nothing happens, pull a plug and see if it is wet. We're crossing our fingers!

You did gap the new plugs....right!
