Default K&B 7.5 Inboard help

You might have to loosen the glow plug in order to fire it. Tighten it up as soon as it's fired.
Bruce, K&B had some machining problems before they sold the operation. The crank and sleeve were not square to each other. I know of several people that had that problem. K&B was trying to get out of their warranty by telling owners that it must have been an unbalanced prop or some other lame excuse that caused the engine to go South.
Another break-in trick is to use toothpaste and light oil on the piston and sleeve to hone it.
The K&B's have a tapered sleeve that tightens the piston up at the top end, this is why it is tight there.
