Hello Bill, Trev thinks you are flooding it, Which is too much for the starter, I always said to my brother to use the valve lifter, Like they do on BSA's. Might be an option to clear it ? Good Luck, Bill.
He does indeed, that very one was designed by Franois Grosset, so is also a Grosset starter."All Godet Eglis use the Grosset starter"
He did use them for awhile, but had too many problems with shear pins letting go, sprags blowing up etc and switched to a Harley Starter with proper bendix arrangement and ring gear. He has his crankcases cast with a little bell housing on thd bottom primary side rear. The starter mounts there and drives through a/ring gear behind the clutch. He has been using this Harley starter, Bendix and ring gear arrangement for at least three years now. I very nearly purchased this setup from him for my Egli project bike, had all the pricing etc, then he changed his mind and would not sell to me.
