ROUGH-AND-TUMBLE ENGINEERING 



eluding to take it easy, letting the en- .1 up, see 



if the governor belt is all right, and if it is, it would be 

 well for you to stop and see if a wind is not loose. 

 It might be cither the little belt wheel or one of the little 

 cog wheels. If you find these are all right, examine the 

 spool on the crank shaft from which the governor is run 

 and you will probably find it loose. If the engine has 

 been run for any length of time, you will always find the 

 trouble in one of these places, but if it is a new one the 

 governor valve might fit a little tight in the valve chamber 

 and you may have to take it out and use a little emery 

 paper to take off the rough projections on the valve. 

 Never use a file on this valve if you can get emery paper, 

 and I would advise you to always have some of it with 

 you. It will often come handy. 



Now if the engine should start off at a lively gait and 

 continue to run still faster, you must stop at once. The 

 trouble this time is surely in the governor. If the belt is 

 all right, examine the jamb nuts on the top of the gov- 

 ernor valve stem. You will probably find that these nuts 

 have worked loose and the rod is working up, which will 

 increase the speed of the engine. If these are all right, 

 you will find that either a pulley or a little cog wheel is 

 loose. A quick eye will locate the trouble before you 

 have time to stop. If the belt is loose, the governor will 

 lag while the engine will run away. If the wheel is loose,
