Pretty sure it's a merc carb there is only one screw, numbers I thought I saw is 9562A-2 and I think the other numbers are 2202?
sweet thanx again but um I guess im gonna have to figure out a way to find parts or custom make them if things are not avaible anymore. the carb seems expensive too. ive seen they vary from $265-$800. What sucks if I try to rebuild it and parts are not avaible ill have a incomplete rebuild>?
