K&B 7.5cc Pro Outboard

[kesso2118]

I've just replaced the bearings in my Pro engine and in the middle of re-assembling the engine. I need to know which way the aircooled head with the "turbo" grooves in the combustion chamber needs to be mounted.

Please let me know whether the higher number of grooves face the carby or the exhaust port or something else???

Thanks,
James

The 3 cuts go toward the carb and the 5 cuts go toward the exhaust port.
