hello everybody, i picked up a log splitter with a briggs 1320202 model engine type 0985-01 code 800051210. it has no spark, i removed the cover and sanded down the module ends the magnet and the top and botom of the module where the bolts contact it. i used a card from a previous change out and on a second attempt tried the dollar bill trick when remounting the module and still have no spark. am i missing something? i was going to change the ignition module next. should i do that or should i try something else first. i don't see a safety switch and didnt expect one from an engine made in 80 but is there one? any and all help is appreciated. thanks in advance.
