Yes if you can. If you undo the linkage to the carb can you manually open and close it. It may just be gunked up from old fuel. The oil will turn to gel after a while and make everything stiff. You may just want to take th engine out, take it apart and clean everything real well.
You're right, it's very stiff and gross. Gotta clean it reaaal good. Imma do everything tomorrow. The place I go to should do most for me.
-Clean engine
-Install missing pieces (Filter, Tubes, Cover, Pipe, Pull Start)
-Tune
And it should be ready to go Friday. =D
