RE: Chip Hyde Jekyll
Christian,
It's hard to tell without the dimensions, but by just looking at the pictures, the stab placement, and chin cowel, I think it looks like a sixty size Jekyll.
If it is a Dr. Jekyll, I can make you a package deal on a couple of OS 140rx's with header, Hatori/OS pipe, new spare EFI bearings, new spare ring, a new Mintor two plug head, a Hyde ARI mount and an new hard to find OS 70B Mixture control carb. One of the engines, pipe, header, and mount has less than twelve runs. Send me a PM if you are interested.
