Folks i found out firsthand who is standing behind the DL when my ring broke. What Bob has said about the other guy is absolutely true and u all need to know. I bought mine from the other guy as Bob was out of stock. He told me from his own mouth that he would back it up with a 2 year warranty. That is a blatant lie. Called him wouldnt return my call so i emailed him and he told me to send it in and he would tell me how much it would cost to fix it. One call to Bob and after $116 in parts for a new piston, ring, wrist pin and bearing she will b running again in 10 minutes. Beware is all i can say. Maybe this is not an appropriate post but the world should know about these kinds of people. I have 2 of the engines and they are the best value out there.. Cant wait to get a 100.
