Well when I bought her it need a new piston and rings because the rings had snapped so I changed it. Ihad a look at the barrel, and that was fine. After I changed all that I gave the top end a clean to get all old oil off becaus I was putting new oil in. I have checked for spark and is getting a really good one. Had fresh fuel and 2 stroke in it. The carb is getting fuel into the bowl but the plug isn't getting wet?
