Honda GC160 Timing Belt Came Off
Cub Cadet yard blower with a Honda GC160 engine. The timing belt came off. What would make this happen and can I fix it without removing the engine. I assume there are timing marks somewhere.

I was hoping someone more knowledgeable would chime in. I have no idea what would cause the belt to jump off except for the failure of something inside the engine.
As for removing the engine from the blower if you have to do it that may be the easy part of the job. See if you can find more expert advice for installing a new timing belt but.... Get the piston at top dead center. The camshaft sprocket should have two marks. You want those marks parallel to the top of the piston/cylinder head. example: If the cylinder is exactly vertical you want those two marks exactly horizontal. If the engine has the cylinder at a 45° angle you want the two marks on the cam 45°

Pilot Dane - thanks for the response. I would hate to get it all back together only to have it happen again. That is why I would like to know why it happened in the first place. The piston is moving up and down. One of the "rocker arms" was off its' hinge. There is no obvious visible damage except the timing belt is off.

Something bad happened. Was the loose rocker arm on the exhaust valve? Anyhow I'd say that engine needs a thorough going over to find the cause before putting money into it. Depending on the amount of damage it may be cheaper to look for a new engine. The GC is Honda's less expensive line of engines so if you are looking at more than $125-150 for repairs I'd strongly consider a new engine.
