MBHD,
I do not have any pictures, but I will try to explain.

You remove the power valve and cut off the spring so there is about 1/8" of the shaft sticking out this is what the new spring sits on. then you make a dome that looks like a smooth beehive this is attached to the fuel side of the metering block the dome has a hole in it about 3/16" to 1/4" dia for the fuel to go through the normal PVR still control the amount of fuel.

Then a spring drops into the cavity of the dome and the power valve pushes on the spring, you change springs to change the rate of the opening of the power valve.

The cavity that had vacuum to release the powervalve now has pressure to push open the valve.

Hope this helps.

Harry
