full throttle performance

What could be the cause for my 03 yamaha 70 to run rough or hesitate at or near full throttle? It almost seems as if the prop is slipping but I don't notice a sudden spike in rpm's. It seems to run fine at cruising speeds and at idle. Is this just a fuel delivery problem, possibly air in the line or could it be something more? Thanks, if anyone out there can help.

I had a similar problem but it went away when I remembered to open the vent screw. Bulb collapsed as well but was normal after vent opening.
I have a 04 yamaha 4 stroke and the only breakend problem was that the throttle wouldn't stay put after about 4k. Easy adjustment to fix, however for a 704 Yamaha control. Take the cover off the control (4 screws) and turn the adjustment screw at the bottom of the front (slotted screwdriver) clockwise to tighten.
