I mostly love to tinker with air cooled 2 strokes and have limited experience with liquid cooled 4 strokes with reverse and such. I picked this Honda up for a price I couldnt pass up. Was stored wrong and owner thought it was seized. Turns out it had oil everywhere including bowl. Started first pull without even a carb clean after 6 years of sitting. Runs like a top. The last thing I need to do is fix the seized gear shifter. And I mean its seized it doesn't wobble or move at all. My question is...where should I start? Top bottom? I don't want to force it unless I have to. Any advice would be greatly appreciated!
