The pusher just quit. I replaced the gas tank and carb last year (junk box surplus) had to fendangle the breather tube. Worked well till a couple weeks ago. No fire, So I did the quick fixes of trying a nown good plug. NOGO, so this evening I had an oppertunity to swap coil packs. The orginal had no spark, #2 no spark. Here is #3. WUHU I get to push mow again!
