Hi everyone. I have a 2005 Honda 4 stroke BF50, hasn't been run in about 4 years. I got it all ready to go, turned the key, the bendix on the starter engages, but does not turn engine at all. I started the engine using the pull rope. Took off on the first pull and sounds good, quiet and smooth. But, the starter is not working, other than the bendix. Battery might be weak, I charged it up, but it has sat for 4 years also. Could it be the battery? Any suggestions. I would appreciate any help.
