Ok so I just got this Honda Hobbit 83’ and it started up ok when I got it but it’s really tough to get the pedals moving to get it started when the motor switch is engaged. When I change it to pedal mode, it pedals fine and easy. I’ve opened the housing to spin the engine by hand and that’s smooth too. What could be making it so tough to pedal start? The chain doesn’t feel tight at all it’s a great tension, so it’s not that. Thanks in advance
