Re: 1981 Evinrude 9.9hp 2str starts but won't run
I'm guessing with this one, but almost positive that you failed to set the carburetor float properly. The setting is critical, and in some of the old rebuild kits they supplied a float gauge. You only have to off a fraction of an inch and the engine will either flood, or starve for fuel.
