what about trying a different carb?C-Mac said:Just took the plug out after running it again in the front yard and tuning it a bit and she does the same thing. Took the guts out of the fuel cap except the rubber dome and there was no pressure inside. The spark plug looked like a number 11 or 19 now but still no power. I know the fuel lines are correct as well since I changed them and the glunk is at the bottom. I am stumped now. does this mean it's a motor issue?
