It has been sitting up for a few months needing carb cleaning. Got that done and made a couple of loops around the yard. Came back, parked it, went in the house for a glass of tea. Came out and pulled the starter rope a couple of times then BOING!!! Locked up. Put it in gear it will roll back but totally locked up pushing forward… Anybody got a clue what I need to try for diagnosis? I’ve been into a lot of engines but never into a scooter engine… this is totally new to me. We did pull the spark plug and tried to turn it over but NOTHING… so, I’m quite sure it is not hydro-locked.
