I have a 6.5 hp Tecumseh that keeps fouling plugs. I ride for 10 to 20 min. & the plug is covered in carbon. I clean it & go again with the same results. It has a non adjustable carb, which has just had new O-rings & jets cleaned. Can anyone give any suggestions? If not enough info please ask for more so I can solve this problem quickly.
Thanks so much.
Danny
