Gentlemen. I'm working on a new Fox Mk 6 Combat special and don't have the instruction manual. I want to bench run it to break it in. I popped the head off and it looks to me as though it has a brass sleeve which would make it an ABC motor with the breakin procedure that I'm aware of that's quite different from a regular sleeve. Can anybody confirm that it is an ABC motor?  Thanks. Roy

I'm sure you will get lots of replys but, yes, the 6 is an ABC motor. It does not nee d extensive break in but it is always a good idea to give em a run on the bench.  I like Powermaster GMA 10% run at a 'wet 2' with a light prop. Would assume you will run with a bladder of some sort. Have fun!  It will give you a stimulating ride!
