Carburettor Overhaul (Tc); Keihin" Carburettor Setting (Tc) - Husqvarna TC 250 2010 Workshop Manual

Carburettor overhaul (TC)

Clean all carburettor components thoroughly with gasoline and dry them with compressed air. Clean all jets and holes thoroughly
blowing them with compressed air. Never use tool bits or metal wire.
Check that the slide valve is in good condition. It should slide freely in its housing, without too much play. Check that taper needle and
main nozzle are in good condition. Check the needle valve for proper sealing.
