Don't worry, before too long you'll be a pro and dispensing good advice like anyone else about a 420.
I assume if you have an Onan with points it is the classic B48G. The B series had points, the next step was the P series which was electronic ignition.
A tune up kit is $39, points, condenser, and spark plugs. The plug wires are special Onan designs. I think I have the materials to make a set, unless I used all the Onan style ends, otherwise we can order a set from Onan.

Last we seen of him, he was running around like his a$$ was on fire and his hair was catchin'.
His hair has stopped smoldering, but the burnt smell still clings on. Folks say it will take some time to dissipate. It was a bummer, though, since I burned the rear end out of my best pair of sunday-go-to-meeting pants.
