How to test non-firing cylinders?
			 
			 
			
		
		
		
			
			I have a 1975 johnson 70hp engine that is not firing on two of its 3 
cylinders. The non firing plugs seem to be geting wet so there is fuel 
to them. Could it be two bad coils and how do I test them? Any step 
down trouble shooting methods would be greatly appreciated for a 
novice like myself.
