ave a 1999 Yahmaha Wolverine.  It has been stored in my garage for the last year with fuel stabilizer in it. Before storing it ran fine with lots of power - no problems.

The problem that i am having is that it idles great, takes gas good, when out of gear but when in gear it has no power and acts like it is starved for gas.

Have checked the carb, intake valves,
exhaust valves, have disconnected the exhaust to check the spark arrestor. everything checks good. need help or any suggestions????
thanks.  

sounds like a carb problem to me.

take it off and clean it out.  nothing to it.  

Might want to check your parking brake switch.
