http://www.ducatimeccanica.com/float_levels.html see Fig.14 independent float style carb (PHM family) OEM Husky single cam family
the carb was set super low for float height,,,,,she was running out of gas!!! float arms are now parallel to carb base. they were at almost 45 deg. bike should be perfect now
Here's an example of why its a good idea to pull the carb. to make jet changes. You catch some screw up like this. I found something similar in the Delortto carbs. on my Guzzi Sport at first carb. rejet. Never seen a motorcycle carb. where the adjustment was anything else but level. Someone had a plan I guess.
PS i had the carb apart 2x before,,,,,to clean inspect the jets and clear passages,,and to learn the Dell Orto ,,but with no research, I just assumed....... the float level was ok. have not tested yet, but by all indications the thing should work perfectly now.
cant say this method is right but what I do is remove the bowl and blow on the fuel tube and move the arms until the needle & seat closes (all mounted on bike) then bend the arms so it closes with the arms level
