No-. engine in perfect shape 



allow the steam to blow out of both cocks at the 

 same time. It is one of two things, and it is difficult 

 to tell. Kither the r rings leak and allow the 



steam to blow through, or else the valve is cut on the 

 scat, and allows the steam to blow over. Either of these 

 two causes is bad, as it not only weakens your engine, 

 but causes a great waste of fuel and water. The way 

 to determine which of the two causes this is to take off 

 the cylinder head, turn engine on forward center and 

 open throttle slightly. If the steam is seen to blow out 

 of the port at open end of cylinder, then the trouble is in 

 the valve, but if not, you will sec it blowing through 

 from forward end of cylinder, and the trouble is in the 

 cylinder rings. 



What is the remedy? Well, if the "rings" are the 



trouble, a new set will most likely remedy it should they 



be of the automatic or self-setting pattern, but should 



be of the spring or adjusting pattern, you can take 



out the head and set the rings out to stop this blowing. 



As most all engines now are using the self-setting rings.

If the trouble i* in the valve or steam chest, you had 

 best take it off and have the valve seat planed down, and 

 the valve seated to it. This is the safest and best way.
