The belt was the wrong size
by William from Fort Washington, Pennsylvania on June 30, 2014
Order the belt using the engine serial number listed on your chart and this was the wrong belt. I returned the belt several days ago and I am still waiting for my refund. I did email you the proper belt number for this engine however you have not updated your chart.
