No need to ever blow into the pitot head to raise the gear.  A piece of surgical rubber tube slipped over the inlet, a piece of electrical tape to close the drain/vent on the bottom, roll the tube slowly to raise the pitot pressure, a clothes peg to trap the pressure, gear will raise and if the pitot doesn’t leak you have tested half of the system already.

Is the engine running?  Your mags are on both.

Yes - this is a screen-grab from the video I took while doing run-up and instrument check.

Before you start digging into the retraction system, did you remember there is an airspeed pressure switch.  Gently blow into the pitot tube and see if the gear. come.up.  

DO NOT blow into the pitot tube.

Get a 6' length of rubber/plastic tube.  Put one end over the pitot tube.  Get a set of hemostats (surgical clamps).  Clamp the open end of the tube and then start rolling the tube up until a given speed reads on the ASI.  Then test the gear.

Sounds like the best explanation for that...it is right below the EGT instrument after all and I confirmed that there is an EGT Sensor on each cylinder's exhaust.

Only problem is that there are only 4 cylinders

I recall seeing a 6 position EGT gauge switch on a 4 cylinder Mooney years ago. 2 of the positions weren’t connected to anything. I would be curious for a photo of the back of this switch.

I still think the 6 position selector below my yoke is for EGT as some have mentioned - I'll find out Tuesday when we test fly the plane.

Browsing trade-a-plane I found a panel that had the "speaker" controls I was trying to figure out.  Thinking this is pretty close to what I have.

Sure looks like you solved one mystery. Knobs are even the same. Really curious on the 6 position switch. The EGT switch is where my bet is placed.
