Back when I knew everybodys' bidder name on flea bay I've corresponded with nearly everybody named in that article .Fact Marshal Trover landed a bunch of main diaphragms for Mac flat back carbs which are nearly impossible to find and offered me one which I thought was very kind of him ..My Homelite 2100 S came from Rich Dougan and with my restoration work on it is the only one I've ever seen to be in full operational condition .I've only ever seen three of that model and I own one of them .
