Puch Maxi with 14mm Bing....it marked the pavement with premix if left parked for a few hours without shutting off fuel valve.
I rebuilt carb, adjusted float hinge many times, but kept leaking. I tried the expensive OEM bowl gasket and float needle instead of knock offs. I tried myron's mopeds' suggestion to polish where the needle seats. Nothing helped. I just now tried to adjust the float one more time and it finally stopped leaking if angled slightly up from the hinge!!!! It was probably the 6th or 7th adjustment that did the trick.
AW HELL YEAH!!!
