GZ250 Sluggish, hesitates, slower than normal????

[Todubs]

Pulled the carb and tore it apart, per the shop manual. BTW, inside of carb was clean and shiny. Put carb back on and no change. Still bogging down under load. It starts and revs fine, but when riding, it has the hesitation and is sluggish (same as reported in the start of this thread).

Oil was changed before storing for winter, I usually change it agian before the warmer weather and riding again.

Wife wants to take it to dealer to let them figure it all out, but I would rather save money........
