How Do You Properly Set Pitch on 2 Blade Power Shift?

I set the prop level(use the angle finder on the hub). Start the first blade using one of the marks. Measure the first blade with the angle finder, wherever just be sure to use the same spot on the next blade. Rotate the prop and set the second blade. Be sure to
check and re-check your angle and adjust the blades if necessary as you torque the hub.
This is how I set/adjust my Sensenich. The angle finder the only way I have to match the blades pitch accurately.

not sure if this will help you
Setting Blade Pitch Using
The Warp Drive Protractor
You should be pleased to know that you are using the Warp Drive Professional Protractor which is designed after the high dollar propeller protractors. When used properly this protractor can help you set your propeller blades within 1/4 of a degree. It can also be used to check wing surfaces on your aircraft.
When using the protractor it is important to always read the same side of the protractor when moving from the hub to the tip of the blade. The outer scale on the protractor is what shows the degrees of pitch. The only number on the inner white wheel is the zero at the top. When you have the protractor set and ready to mount onto the tip of the blades, tighten the red knurled knob where it reads "Lock". This will lock the wheel in place so you can't bump it and change the angle accidentally. Please follow these instructions carefully. If you have any questions please do not hesitate to contact the factory and we can talk you through the procedures.
1. Determine your starting point. There is no need to adjust the position of your craft to set the pitch in your prop. Place the protractor against the hub of the propeller to find the angle the craft is sitting. On a tractor application you would place the protractor against the hub with the white bar in your hand and the opposite side on the hub. On a pusher application you would hold the white bar side of the protractor against the hub. It may be necessary to remove the top bolt with the wing nut and let the bar swing down, then hold the protractor directly against the hub.
2. Setting degrees of pitch. ATTENTION! Always set the degrees of pitch at the tip of the blade! Determine the amount of pitch you want and rotate the protractor wheel the same number of marks from your starting point. Example: If your aircraft is sitting level, your starting point would be zero. If you want 10 degrees of pitch, move your protractor wheel ten marks in the outer scale.
Mount the protractor at the tip of the blade with the protractor wheel towards the rear of the craft and the clamping bar towards the front of the craft. This is true whether you are in a tractor or pusher configuration. With the protractor mounted at the tip of the blade, rotate the blade until the bubble shows level. Hint: While rotating the blade with one hand close to the hub, gently rock the blade back and forth at the tip with the other hand. This method will result in smooth, fine pitch adjustment. You will also want to pull out on the blades when setting the pitch to ensure that the blade collar is seated in the hub.
When setting the pitch of your propeller, always set the proper angle of pitch so your engine will achieve its maximum static RPM on the ground. If you want better cruise and top speed performance, set higher pitch for a lower static RPM. For better take-off and climb performance, set a lower pitch for a higher static RPM.

snielsen,
Not to get off the subject but is that your Dogue De Bordeaux, I have 3. What blood line is your Dogue?

Reduce pitch/increase rpm until you find a sweet spot. Most will recommend 2900, 2950. This will allow you to use the most available Hp from the engine. But do not go more than 3000.
You'll have to mess with it and change the setting until you will get the most out of the combination for what your running.
