<VV> Broken Camshaft ?

[John Howell]

                        I have a 140 hp that I have been having trouble 
getting it to run smooth.  All four carbs have been rebuilt, new fuel 
pump, new Clark`s fuel filter in front of firewall, new plugs and wires, 
rebuilt distributor.  All of this had little effect, it would run good 
sometimes and then bad, really erratic. Compression test showed # 1 - 
155, # 2 - !55, # 3 - 154, # 4 - 165, # 5 - 154, # 6 - 157.    I pulled 
the tappets on # 4 and found that the exhaust tappet had lost the keeper 
wire and the internal parts were just floating around but still there, 
the keeper wire was missing, I replaced the bad tappet, put it all back 
together but it still ran bad.
                       Then I decided to check all the tappets so I 
started on the passenger side with number one, three and five all looked 
good so I moved over to the other side then there was old number four, 
the bad apple.   You are supposed to be able to adjust #4 exhaust next 
but that valve was being held open and # 4 intake was real loose, just 
the opposite to what it should be with the crank set to zero and # 1 firing!

                        Question: Could the camshaft be broke and 
causing some valves to be out of time?  Could the missing keeper wire 
have caused the camshaft to brake?

                        Thanks
