It was tuned , and has been setting for a while but no gas in carb when stored? It took a while to start and then noticed no full speed. linkage? carb need cleaning ? adjustment? it has work flawless always so am stumpped this time.

Take the cowling off and watch the carb linkage as you twist the trottle grip. If nothing moves, you have a problem with the twist grip or something else in line between the tiller handle and the carb/timing plate.

If everything moves normally, it's probably a clogged main jet in the carb or an ignition problem.
