carburettor overflowing

[Dave Mann]

I've never tried fitting extra fibre washers under the seat, I've always moved the collar, however if you haven't got the original weight brass split pins and are using ordinary split pins make sure the tails aren't too long, they can stop the float from going up. To reseat a needle and valve I hold the needle in a pedestal drill and with it on its slowest speed add some T cut to the needle and present the seat to the needle. I use very little pressure and keep lowering the seat away from the needle, too much pressure or allowing it to run dry will mess it up.
