We finally had some warm weather yesterday, so I dragged all the trikes out and got them washed and we rode them all. Saved the green one for last. Kicked it once and the kick starter stopped 3/4 of the way down. It won't turn at all. I've heard of engines seizing, but not when it's not running. Is there anything common that might freeze up on this engine that anyone knows about? It's an '85.
