I have in the past mentioned getting ignitors from older weedeaters, chainsaws or blowers and such from yard sales or where ever.
This is an aftermarket conversion kit ignitor that I use to trouble shoot problems with.
I have one with two 10" wires and Alligator clips. Unplug your lead from points/condenser or questionable stock ignitor and clip to one lead, clip other to ground to test.
I have also used them on everything from Briggs singles and twins to weedeaters, any engine with points or other type of ignitor can be converted with this kit.
I don't sell them, got no association with them other than I use it and it's cheap. Just wanted to pass it along as an alternative to the OEM ones.
