Thanks your and hrx answer
Let's see how much money would be that job, and new valve guides and valves

I have another idea. I have an empty block with this Zylinderkopf what is full broken inside, withouth carburator and sell it such a room decoration. The alu can be polished nice


What would be the better business?
Thanks again
Tibor

I talked to the master. He doesn't accept this job. Till he would make it he would make three or more schleifen/bohren of cars. If I would have a workplace with a Drehbank...
That's all. It will be a room decoration :)
Tnx
Tibor

By the way! In which year this block would be made? Was it Columbus or Horex already? It had right side brake arm and left side gearbox arm, the clutch/kupplung arm also was quite different.
Tnx
Tibor

Wüsche alle Forumsmitglieder frohe Feiertage und ein gesundes neues Jahr 2023

Here the right name Horex Columbus
"
It not tells anything about my blokk. It is hard to translate a picture to hungary. :)
I watched that blokk in backyard of a farm when a took a journey by train. Other time I go back by car and I have bought it for 100HUF :)
It was without Zylinderkopf and Zylinder only an empty blokk.
It was about in 1970

It was something technical presentation in a school earlier. Inside all bearinghouse is broken
but the aluminium was possible polished to very shine

So
I wish you and every member peaceful Xmas Holydays
Tibor
