Hi All,
I've got 2 Bolens BL100 string trimmers, one is 6 years old, the other was bought new in Dec '07 and stored until last month. The older one quit throwing spark, so I got the "new" one out and got 30 minutes use from it before it, too, quit sparking. Bought 3 new plugs and none of these will spark in either engine. Took the old one apart and tried all combinations of mag/flywheel clearance and plug gaps, nothing (not gonna play with the "new" one yet). Here's the strange part, I can pull the plug off the boot, insert a 1/4" drill bit into the boot and get spark by holding it next to the block! It's weak as hell, but a spark... Anyways, I bought a new magneto assembly just to see if that's it, but I'm not too hopeful. All I can see is flywheel (magnets), magneto, or spark plug. Do these things take a special plug?
