VV-XI SLOW SPEED

I will take pictures and attached them soon. Thanks for all the responses so far.

As I was rummaging through a tub of parts tonight I discovered something that may help you. It is a round dial speed control that I took off of a mid-teens VV-XI. I think you may have this type on your machine and it is very easy to adjust. If yours has a screw in the center of the knob, set the pointer to 78 and hold the knob there while turning the screw. I am not sure which way the screw needs to be turned to increase speed but it should be obvious when you try it. Bring the speed up to 78 Once set, you will have a speed range both above and below 78 when you turn the knob.

They say a picture is better...

Here are pics of the board and motor. I know from research that my 1919 VV-XI should have the speed control with the see through glass. And I also know the motor is the wrong year since I had to move the crank hole. But I still can't get better than 65 rpm no matter what I do. I even modified the part the adjusting rod attaches to in hopes the 3 weights would swing farther out thus increasing the speed but found out they can not swing out but so far before they hit the metal assembly it's attached to.

That looks like a setup from a VV-IX. From what I can see in your pictures, it looks like the governor is set too far to the spring barrel side. There are two ways to correct this.
Method 1: With the motor completely unwound, loosen the setscrews which hold the governor shaft bearings in place and while holding the ends of the bearings, slide the governor away from the spring barrels. Tighten one of the setscrews and, after allowing a slight amount of endplay in the shaft, tighten the other one. Wind up the motor and check speed. If the motor is now noisy, return the governor to sits original position and try method 2.
Method 2: Loosen the setscrew on the collar and slide the the governor along its shaft toward the flywheel end. When you look at the collar end of the governor, which is the end closest to the spindle, you will see 4 screws going into the brass collar. Three of them hold flat springs to the collar and the fourth holds the collar to the shaft. With the motor run completely run down, loosen the setscrew and slide the governor assembly along the shaft away from the worm gear. This will move the flywheel away from the pad and allow the motor to build up more speed before the flywheel contacts the pad. Be sure the setscrew is tight then wind the motor and check the speed. It should not take much movement to get to the correct speed. If the speed is still low, let the motor run down and go through the procedure again.
When you are done, recheck endplay and the tightness of any screws which had been loosened.

Thanks Jim. I will try that tomorrow when I get back from work. I will let you know how it works.
