    MJD, do you have a sharper image of the Big Otto? I had one of these in the 1970's with an OK Cub 099 on it. I still have the engine and I would love to build another one.

    I have a 1970's Enya .09 that has been run with a TF 8X4 since broken in, it still hand starts. I lost track as to how many hours are on it. A little varnished up but it runs well.
