RE: New US engine USQ57B
To Hircflyer: You have a good Quadra in my estimatiion. It is one of the earlier ones, made in 1981, and my guess it has points. Should be easy to hand start. I am not at all familiar with the plane you mention - therefore cannot comment. However, I had good success with airplanes in the 17/18 lb. range with 18 x 10 and 20 x 8 props. Let that be a guide.
To RCIGN 1: You know what. I also have one of those old chainsaws with the short coil wire. It is a Poulon. At my first visit to the factory in Huron, they were making chainsaws for everybody. The guts were nearly identical, and the plastic parts on the outside gave them their individual identity.
To Flypaper 2: Thanks for the additional information. I missed any move to Florida, always was associated with Trail, and Huron Park. Must be it didn't last long.
