Its simple, light and reliable.

I really like this idea. The airplane I have this engine installed on is a smallish FW 190. The engine itself gets in the way of running it forward, but I never thought of using a supported cable. This creates more options. Thanks for the ideas guys

Status: offline 		I use a nyrod (turned/curved 90deg to make some friction) throught the side of the fuse. I put a servo screw in the end to pull on. When it is set right, the screw head is flush with the fuse when the choke is off. Almost looks like a cowl screw, etc. Sometimes a bellcrank is needed.

Mine is a 70 in fw 190 and I had no problem running it foward. I didn't even extend the arm. I hooke a ball link to the arm and nyrod and it just clears the engine. A extended arm would make it that more easy.

Status: offline 		I made a guide from aluminum and ran the choke control out front. Didn't alter the choke arm, just used a metal clevis with the metal clip to keep it closed. You hardly notice the wiring protruding out the cowling. If you have a radial engine cowl its easier.

Basically the same setup I did. And if I were to put the radial engine in it could be hidden like yours.

Status: offline 		RBean whats the deal with your plug ? It looks like you are getting blowby between the ceramic and steel in the pics, could just be residue from oil.

IF the OP wishes to follow this set up I would offer caution:  After choking ensure that the Ignition is OFF. 

Reaching into the prop arc is always a dangerous activity.
