Start off with the simple stuff with the bowl on the carb. The needle and seat-look at how many threads are
showing so you get the fuel level close to where it was. Remove the needle and seat and spray compressed
air in it with the pointed tip held open. Before you screw it back in, lube the rubber O ring with a tad of oil so it doesn't tear.
Note: fuel level height is performed with the engine running. If you don't have a clear site plug on the side of the bowl for setting
the height then remove the side screw and adjust the level so fuel is just sitting at the bottom if the threads. Test it by nudging your
fender and gas should trickle out. NOTE: do not drive the car with clear site plugs cause they will melt. They are only used for setting
the fuel level.
These are from my web page.
Remove lock screw while holding adjustment nut. (note on assembly-turning this nut CW lowers the float and turning it CC will raise it.
Then lift nut off and note where the paper gaskets are.
Then unscrew the needle/seat with your fingers, it's 1 piece.
Fuel level site plug. Note tin gasket.
