[SEL] two questions about hit n miss engines

[David Rotigel]

Hi Jim and Alan,
	While it's almost true that a hit and miss governed engine should not  
hit "every time", it's only ALMOST true. Several things must be  
considered.
		1.) The great majority of hit and miss engines are 4 cycle. Four  
cycle engines "hit" only every other time.
		2.) Hit and miss engines that were used in various applications  
would "hit" every other time while under load for a SHORT time.  
(Consider, please, a buzz saw rig, or a lift [as when 	
			elevating a boat up to dry dock, or a load of bricks to the top of  
a structure being built.]) In such cases the engine would hit" every  
other time for, say, 5-10 seconds and then 				return to "hitting"  
only once in a while.
		3.) On other (most???) applications Alan is correct--if the engine  
is "hitting" every other time over (most of the time) you should get a  
bigger engine.

PS, Yes, I know about 2 cycle engines! The MAYTAG single is the most  
common, but no one has ever seen one running, so that does not count!
PPS, Ask any real engine collector "Do you own any MAYTAG MOTORS." If  
he/she/it responds "No" you can rest assured that he/she/it is a LIER  
and CAN NOT be trusted!
PPPS, How was that last PS for being politically correct?
