Restoring an Old A-65-8F

[weiskopf20@gmail.com]

If you elect to replace the engine, give some consideration to the C-85 with the O-200 crank, pistons, connecting rods and carb. I used the STC from Aircraft Specialty Services and phone help from Don Swords. Everyone who has flown the Cub with this engine has had a WOW experience!

Google Don Swords at Don's Dream Machines. He is a real gentleman and will take the time to make you smart.

Don can also handle the STC.

My "free" C-85 had toasted crank, cam, cylinders and carb. It was missing the mags. So it was just some extra bucks to go the STC route. In retrospect, if I had a better case, it could have been done cheaper. But the C-85 with O-200 parts -ROCKS!

Does the STC require modifying the vertical stabalizer?

There are no airframe mods required by the STC. NOTE: the CAM is remains a C-85 CAM. This is really a good thing. The C-85 CAM in this mod produces an honest 97 HP. The O-200 is a 100 HP engine which is lucky to pull 90 HP. Also the C-85 CAM red lines at 2550 RPM whereas the O-200 CAM red lines at 2700 RPM.

The fuel burn went from 4.00000 GPH with the A-65. No matter what we did, the fuel burn never varried. The modified C-85 gets 4.6 to 5.3 GPH. Cruise with the Sensenich 46 pitch prop is 80 mph at 2300 and 2400 takes me up to 85 - 90 depending on the load. Since max cruise is 90 mph, I keep the RPMs at 2350.

This winter I plan on adding an 8 gal. aux wing tank - mostly, just to have a larger reserve after a 2 hour leg.

Any more questions?

Nope. Thanks for the info...
