governor weights by LN

This is in response for your post on feb. 24 on governor weights.
They are designed to work to-gether,spring tension against centrifugal force to controll engine speed. You should not modify one with out the other. That is why some engines surge or are hard to controll at certain R.P.M.'S. The governor spring and the weights should be in contact at all the rpm range of the engine.If there is a space in betwwen them that is when the engine starts to surge, run erratically and does not maintain a steady speed.
The governor by design has a droop speed that is controlled by the spring tension and its design.
Droop speed is the max rpm's at no load, and the max rpm's at full load.
There is a formula that you can apply to find out what the droop is in any governor. Some governors have a droop speed adjustment for kepping the rpm's closely controlled under power. Gen set usually have this controll to keep a true 1800 rpm's to maintain 60 cycle a/c output.I have friend of my that runs an MM, the governor is a bit twicked and he does pretty good pulling in two classes.
