I may mount the next one under the wing inside the fuselage.
I have never had an easier to operate engine, certainly not one for racing. Just release the fuel line clamp, hook up the battery, and turn it with a starter. If the last run was good, the next one will be too. No need to even look at the needle once the engine is broken in and tuned up. From dry Phoenix air to 98% humidity in the swamps near KC, it ran the same setting.
