I was just out for a spin and my sled is still amiss. I have compression on my third cylinder and I have spark on the plug when I haul it out to check it. I tried putting my hand on the y pipe when I have been going for a few minutes and the first two sizzle and the third is just warm. Not sure where to go next. I tried several different plugs and tried adjusting the fuel air screw just a littl. Any ideas?
