As far as the carbs not opening completely horizontal, my 100hp is the same. It's limited by the second carb throttle linkage which has a metal stop. But that's not your problem.

Did you try Charlie's tip of hitting the enrichner during bog? Or how about having somebody squeeze the primer bulb during bog?

You know, that last 3 inches of throttle is where the timing maxes. What max timing did you set to? Did you check the flywheel cover timing pointer adjustment? If you look at the max timing adjustment there is a little blue plastic bumper sticking out of the other side of the timing arm. About how much is sticking out?

I thought the max timing for that motor is supposed to be 25' BTDC @cranking. That's what mine is set to and I believe our motors are the same except for carbs.
