Hi Lee, To my ear, the 2nd video is a normal sounding A4.  They sound like a 
sewing machines.  The first time I heard mine run, I had the same reaction. The 
first video, sounds like a normal A4 but there seem to be some kind of movement 
of some kind.  My first thought was that it was in gear and the prop was 
spinning maybe. However, as someone mentioned, that could have been a loose or 
aging engine mount.  I didn't notice any engine movement though. The coils on 
the A4 can be a bit delicate and crack when they over heat.  That could also be 
the source of difficult starting.  Especially, if it started easier cold and 
got more difficult when it was warmed up.  I kept a spare coil, spare carb and 
spare fuel pump on board because these were always causing me trouble.  Well, 
not the fuel pump really but, I figured it was good insurance.  I would try to 
swap out the coil if I had an overheat. As has been mentioned, these are very 
durable engines and don't die easily. Danny

Ahoy! When our C&C29 MK.1 was taken out of the water last season the engine was 
left running... until it eventually just stopped. We've just tried starting it 
for the first time using a bucket of water, and whilst we did get it running; 
it doesn't sound like it use to! Could anyone familiar with Atomic 4's please 
listen to these videos and let me know your thoughts? Link to videos:
