Purchased a set of dual Dellorto 40's from a guy who claimed:
"THESE ARE SOLD WITH NO WARRANTY, THEY ARE LIKE NEW, BUT NO REFUNDS SO MAKE SURE YOU WANT THEM. NOTHING WRONG WITH THEM I JUST DON'T WANT ANY MAYBES"
Turns out they had bad bearings so they were like on off switches and wouldn't return to the throttle stops without force. Tried to work with him and ended up having to dispute it. I won!!! Got the money to fix them now!
