Hey ! Yes g3 carb to remove there is a clamp holding it on the cylinder
Like a hose clamp use a flat blade screw driver to loosen. disconnect throttle cable
disconnect fuel line and kill switch wire then jiggle off carb
All you should have to do is remove the two screws under carb and remove float bowl
carful not to damage gasket
you will see a little brass fitting
this is the jet remove it and blow it and the holes under it with compressed air
