The gasket could be either a rubberized cork or a thickish paper.
EDIT: Another thing: when you get the governor out and the plastic gear looks OK, hold the governor by the gear with one hand vertically and flip the weights with the other and watch the small valve on the inside and see if it moves smoothly and does not stick. This can cause erratic shifting also.
Actually post up a pic of the governor when you get it out

Much appreciated 👋🏻
Aha I see,
I’ll try to do it and post pics when removed
