Problem fixed: Hard start and poor to no idle

Got this engine home and expected dirty carbs. Closer inspection also revealed the idle mixture screws on both carbs were snapped off by previous heavy handed mechanic. Upon disassemble i found a missing gasket as well as a small amount of dirt in the carbs. Cleaned and blew everything out, replaced 4 tired and or missing gaskets, the new idle screws and tension springs and serviced the lower unit and is good as new. All for $60 worth the parts and less than 2 hours if my time.
