FFKiwi,

Arne and I discussed the Baby-Dyno last time he was at my house. I thought he made a production run but he said he never did. I even marked one of my boxes as a third production run but I'll have to make a new box liner to correct it.

Evidently guys were having some difficulty starting the ABC versions so he made a run of steel cylinders that could be retro-fitted for better performance.

He brought me one and I have a picture of it. Arne also told me that if you block off one exhaust port with your finger it will pick up about 500 RPM.

We lost Arne so the last engine he made was an Elf Corncob.
