Small Bore AF Engine
 

Does anyone know of a source where parts for this engine can be acquired. Specifically we need new pistons, and I assume the head gasket is different too. We haven't yet disassembled the engine, but it is tired and needs to be rebuilt. Any leads would be much appreciated.

My first ports of call would be https://www.belcherengineeringltd.co.uk/ and mafcgb.org.uk

If they are stocked in the UK then that may be your first place to check for convenience. Egge would likely be next choice if they can manufacture a 3.05 bore type piston or there is another type piston of similar bore, compression height, and pin diameter. Where it might get complicated is when you need an oversize. I don't know how thick the cylinder walls are on the AF engine or how far they can be bored out. It would be interesting information to know.
