What is the carb setting for a 372 husgvarna - Garden

The jet skrews are fuel not air skrews, the more they are unskrewd the richer the mixture becomes, basic settings are one and a quarter on the L skrew and one turn on the H skrew, you will have to fine tune from there, idle speed should be around 3000rpm, and max speed should not exceed 13000rpm, this should be set with a suitable engine tacho, when fine tuning always start with the L skrew first, start gently skrewing it in, the revs will start to increase as it leans off, when it starts to die because its too lean, unskrew until the revs pick up again, as you keep unskrewing you will hear the revs start to drop because it is becoming richer, leave it there, now blip the throttle, it should pick up instantly, if not turn the skrew out a further 1/8 of a turn, the H skrew is like a govener the more you skrew it in the faster it revs, so do not exceed the 13000 rpm or this is a good chance it could seize, before any adjustments the fuel filter in the tank should be clean or replaced, the air filter should be cleaned and fresh fuel should be used.
