The Linkert carburetor had the wrong venturi for the 1300cc engine installed. I even could not get the correct part from the USA. An old master in a machine shop, who still had a "sense " for such an old rubbish, made the venturi after a drawing I prepared. I am sure the final product did not look different than the original part. With this venturi installed the engine started after the 3rd Kick and ran from then on without problems. Taking that motorcycle for a ride is something special, even after years of ownership. Getting used to foot clutch and tank shifting is relatively easy done - practicing helps a lot!. Often I have the impression, that the Flathead engine has more power than just for pulling me around. So I hope that one day I will be able to find a sidecar in a reasonable shape and make a big rig out of it.
I learnt a lot during this restoration and if someone is willing to spend a lot of time and money with this outdated technology and has the space and the tools to disassemble such a motorcycle I would advise him to own and restore such a motorcycle. Because not only "old Indians never die"!!
