I bought a GP 61 at a flea market for $380 new in box! It's mounted on my test stand and yes I had some trouble with the throttle hook up. So the Falcon 25x8w prop showed up today. I cant believe how easy it started. I rocked the prop and saw the fuel flow towards the carb. So I switched ignition on flipped maybe 4 times and then thought to choke it. 3 more flips and it popped, choke off, it popped again on the 4th and started on 5th flip. After a minute or so I opened her up and it roared. I never touched the needles. After a short run I stopped it. It restarted a number of times on one flip. Now all I need is an airframe. Pleased in Pennsylvania!!!!!!!!!!!!
