GSX600f annoying Rubber stopper plugs in pilot jet tube

[Angus]

Do these jobbies actually have a purpose? Apart from falling out and getting lost. They don’t seem to be mentioned in the Haynes book of lies I have. Are they intended to be a tight fit and completely seal the tube (I think Special K suggested they should be a snug fit) or just sit held loosely by the float assembly and allow small amount of fuel to pass through, sort of like a valve or something? I did wonder if they were some kind emissions gizmo, all the carbs I’ve stripped before have just had the pilot jet tube open so is it possible to discard them.

Cheers Angus

They are to seal tightly to prevent fuel from flowing through, but are removable to allow for access to remoe the pilot jets under them.

When installed, the normal flow of fuel to the pilot jets should be through the main jet into the emulsion area, then cross over to the pilot jet area. In general, not haveing the stoppers will cause issues for the fuel delivery for the pilot jets.
