I am having almost the same problems and I recently adjusted my valves and it ran great except for at full throttle. So, I pulled the carb and found some debris in the main jet. Put it back together and now I can't get it to run. If I pull the diaphragm with the needle it runs.
It's running really rich and I can't figure out why. I've pulled the carb and checked it at least 5 times and can't figure this one out. Any help would be greatly appreciated.
