From what you quoted above I too feel it's a fuel issue. On a properly running engine, when you go full throttle, the carb opens wide open for a while till the RPM's of the engine satisfies the governor and the governor starts to close the butterfly valve on the carb till the set RPM is achieved. Yours when it opens wide open it's leaning out, starving for fuel. You pull out the choke and the fuel to air mixture then richens up enough to satisfy the needs of the engine.

What's wrong?

1. Did you check the strainer screen on the fuel shut off valve at the gas tank? I would blow some compressed air through the fuel line to make sure the screen in the tank is clear. If this solves the problem, then your done. Be careful when you do this, don't overpressure your fuel tank!

2. Did you check your float level in the carb to make sure it's set properly? If it's set to low, this can cause the fuel mixture to lean up because it doesn't have enough fuel in the bowl.

3. Did you soak the carb in a parts cleaning solvent when you put the kit in it? If you didn't there could be dirt, or fuel varnish clogging the high speed fuel passage within the carb. I use Gunk's Carburetor Parts Cleaner. It comes in a gallon can and has a basket to put the parts and carb body in for the soak. Fully disassemble the carb and put all the parts and carb body into the basket. After a 24 hour soak, blow all passages with compressed air to clear them out.

If these suggestions don't work then I guess it is time to visit the 80 year old engine guru down the road. LOL! Good luck!
