Have a 70's vintage 2 cylinder yachtwin, pistons seem to hit top of head (even with new head/gasket) - is there something I'm missing? Can rotate back and forth but when either piston gets near to top it seems to hit and won't turn any further.

Cylinder head upside down?

That's the first thing I thought of, too. The plug holes should face the port side of the motor (when looking forward). This pic is from the smalloutboards site...

Duh! That was it - thanks! Reminds me of the Monty Python skit - "you mean spell bollor with a k? Kolor - what a silly bunt..."

One more question - the engine pulls over hard, seems to be the pull cord/gear assembly since the head spins easily. Kind of a funky setup for the pull start. Anything I should look for?

Thanks
