Hmm Thanks for the info on the counter rotating and the twins.

Starting the outboard engine and tuning it first should make it run out of fuel before the inboard engine wont it ?

I have at least 10 norvels here and prolly 18 cox engines at least that assembled cox engines.
I love my 1/2a engines.
I have this addiction of leaving flee markets and anywhere else I can find them with a giant pile of what someone else thought was junk 1/2a engines that I take home and make into a pile of sweet lil running 1/2a engines.

I guess Ill sell that reverse teedee crankshaft as they are hard to come by anymore.
if I dont use it on this then I wont be using it anywhere.
Ill just shove a pair of .061 norvels on the P38 Twin.

I learned the break in procedure on the norvels the Hard way and ruined a few before I figured out not to add any castor at all to the fuel I break them in with and to run them lean and mean. I also preheat them a lil with a heat gun.
