Mr. Pipercub
I plan on using this engine with the Balsa USA 1/4 scale Fokker D VIII or the Stringray 120. I will try the standard carb first with the 18x8 prop. If that does not work I will put the larger carb on it and try a 16x8 prop.
I thank you for your help with this. I have just called Peter and ordered the muffler for my Ryobi.
Thanks
