Running like a champ! Thanks all for your suggestions and input. Ended up doing the following: 1)replacing spark plug and adjusting the gap, 2)cleaning the spark arrestor, 3) lubricating throttle cable, 4)rebuilding carb, 5)replaced gas lines, 6)cleaned fuel tank. Not all work was required to get it running again, but wouldn't hurt either. I believe the problem was bad fuel. The gas lines were corroded which lead to my carb problems I'm sure. Thanks again!
