Heinz Kornmüller's cast iron
kit formed the basis for this engine. I started to build this model with the
small Rotwerk lathe and mill which I later ended up replacing. Because of small
inconsistencies in the drawings and my limited metal working experience, I had
to redo several of the smaller components. For the valves, I eventually built
completely new cases with modified valve guides.
After one year, the engine was ready for its first test run. Subsequently, after
complete disassembly and a paint job, it refused to run.
Success did not come until I replaced the carburetor by the type Jan Ridders
describes on his model engineering pages. Now the model runs reliably and the
rpm is easily controlled.
