Thistrouble will usually disappear after the engine hasrun a short time. To Correct for Speeding Up If the engine speeds up when the load is thrownoff, it is either because the valve has too much lead oris sticking through lack of proper lubrication, ormay possibly be leaking, due to wear, as speeding 78 SHAFT GOVERNORS up, due to the adjustment of these governors, is notlikely to occur. Care of Governor The governor is a simple piece of mechanism, butit is one of the most important parts about the engine,. CD riG. 19 © © FLEMING ENGINE GOVERNORS 79 and should be so treated. The springs should be dis-connected occasionally, and the governor parts andvalve gearing should be tested, by hand, for freedomof all bearings and joints. It is also a good plan totake the governor bearings apart occasionally, andexamine them to see that they are getting properlubrication. Clean them thoroughly before puttingthem together again. Before starting up the enginealways see that all bolts and nuts are tight. If thegovernor is equipped with dash-pots keep them fullof either glycerine or equal parts of cylinder andengine oil.
