Tillotson Copper Inlet Seat Gasket is designed to make a seal between
the inlet seat and carburetor body to prevent damaging the carburetor
body when the fuel inlet seat is changed.
For older carburetors you
may need out 709
or 708 gasket
alignment tool to
make the gasket and seat I.D. concentric.
install the new gasket, and you should every time you replace the
seat, You need to gently install the seat against the gasket then
tighten slightly. Loosen the seat but keep it contacted to the gasket
then tight further. Repeat this process a couple more times. This
forms a groove in the copper gasket making a leak-proof seal. If you do
not follow our steps then you may have a leak and the next natural
step is to tighten it further. This may result in pulling the threads
out of the seat cavity. If you cross thread or strip the seat threads
then you have ruined your carburetor. Tillotson does not offer a
carburetor body therefore you’ll need a completely new carburetor.
