and if you lose the little bugger good luck finding a place
to buy one.
I went to every auto parts place and every place else I could
think of.
finally I went to the honda/kawa/suz/yama dealer near by and
they came up with a number to order.
I even tried the harley shop ( they use kehien on their bike s also.
and they could not find a carb with a mixture screw in the computer.
anyway
honda part # 16075-KG8-901 is a honda mixture screw o-ring.
it is like $2 and change for 1 and can be ordered as 1 or more.
I got 4 just because.
