RE: K&B .65 Sportster
OK, I still want to get this thing running reliably. Looking through the muffler port, I don't see any ring on the piston. Therefore, am I to assume it should be broken in the same way an ABC/ABN engine is--running flat out just a tad rich (I haven't been able to get it to WOT yet because it quits) .. Or should it be slobbering rich as a ringed engine would be? Also, my postal scale is getting this thing at 20.1 oz. with the muffler on it. Is this in the ball park or is my scale lying to me? BTW, I was looking for numbers somewhere to identify what series it is since someone mentioned above that they had part no 5800. I can't find any identifying numbers anywhere on it. Any ideas why that is?
