Tim,
The flywheel is small on this engine, in fact, flywheels are not really necessary on most of these small double acting engines.
It is there just to help it thru any self induced dead spots (timing not set up perfectly) and assist in keeping the engine at a constant speed when being loaded by say a propellor. But on a single acting one like a wobbler, they are necessary to get the engine onto the next power stroke.
It does help having the flywheel lightened towards the centre, as it then puts more force into the outer periphery of the wheel, similar to a gyroscope. So even a few holes or recesses do help.

In that case a flywheel on my engine will be essential, especially when I start setting the timing, I've never timed anything before.

Enough said, I'll see if I can drill a few holes to move the weight towards the outsides.
Thanks John :thumbup:

Presume the crank journals set 90 degrees apart on this engine? Do you have a method of achieving this or just by eye?
