In the gasket set for a 192 Galletto there are two cylinder base gaskets. One paper and on of thicker material. Suppliers sell these individually and list the paper one for the pedal model and the thicker one for the electric start model.
Can anyone tell me why they are different. many thanks Phil.
Belated reply but - Probablty to reduce the compression ratio slightly to give the weedy electric start an easier time. I have a villiers 250 with a SIBA electric start - which needs lowered compression to allow the electric start to work properly. The head gasket is about 1.25mm thicker than standard.
