I have a Craftsman string trimmer. It didn't have a spark so I bought
a new ignition module. When taking off the old one I didn't notice
what the gap was. How do I make sure I have it position correctly.
When I was servicing a lot of Generac Generators
that had the B&S Vanguard engine, I had a strip
of brass (nonmagnetic) shim stock of the proper
thickness that I slid between the coil and flywheel.
It made it quite easy to set the gap. You may be
able to use a standard set of brass feeler gauges
on an engine that small. I might guess .010".
