****OK, I missed that, but still hardly a major modification*****

Dream on Ron. Changing the system by which the engine is controlled is at
least, very least, a major modification. There are numerous failure
scenarios I can think of.

"The system" is just a push-pull cable. Crikes, sticking a vernier twister
on the panel end is not a major change in the design. You want to go get
a 337 before you put fuel in the plane, that's fine by me, but it's not required.
