Okay, Model 10247 LB mower with Susuki 2Cyc engine. I cannot get the pot licker to start becasue I have no spark to the plug. I know it is not a bad plug because I put it in my string trimmer and was able to get spark. For some background, earlier this summer I could not get it to start, pulled the plug and the insulator was brown on one half and white on the other, I mean right down the middle 50/50. Put in a new plug and it started. Besides the Ignition coil what else could be the problem with my lack of spark? Thanks in advance.
