[QUOTE="jds535, post: 1428553, member: 123830"] The plug gap was very small ( I know I should look it up and set with a feeler gaude ) but when I cleaned it I opened the plug gap and now it runs even worse than before. Not sure if that makes it look more like weak spark or not?? I will try the jetting. They are cheap enough. BTW - after increasing the plug gap and running it for half an hour, the color of the plug was still tab when removed. [/QUOTE]
