This engine was use in a Dirty Birdie for two seasons. In my part of the country we fly on the average 35 weeks out of the year approximately once per week. I had four .61 engines on four different pattern planes. Judge for yourself on the amount of run time as flight time was split equally between the four planes. I can't find the stock muffler so the engine is being sold with the header and tuned pipe just as it was flown.
Performance with the pipe was good, but I actually used it because I liked the sound.
Plans are to cancel this listing on Sunday Oct 29.
