Glad to hear you're making progress!
We recommend Autolite 437 spark plugs gapped at .025.
Do the spark quality test though, just hold the end of each plug wire about
a quarter inch from a good ground and have someone roll it over, key on.
(use an insulated tool or you'll know for sure if it has good spark!)
Spark shouldn't be yellow/orange, it should be blue/white and jump that gap.
If not, then that resistor "may" be the problem. Can't say for sure yet that it is.
As a temporary test, you could jumper a wire around it, but don't run it that way.
To check for flooding or starving, pull the choke out a bit while its running
and see if that helps or hurts.
If it hurts, it may be too rich.
If it helps, it may be starving for fuel but it also may be a weak spark problem.
Let us know what you find.
