What Is going on? look at my plugs please.

If it was fuel related you would have noticed fuel dripping out of the high speed circuit and it would load up very easily. If it was not getting fuel into the carb it would most definitely have a hesitation bog. I have a feeling this was a used ignition and it is new to you. Even if the third channel does not fix the problem you know the second one works. Run that on the front cylinder and see what happens.
 
That almost clean plug is getting washed by fuel. Are you sure on the jets, compare them between carbs, one might have been drilled out. Check n&s not sticking open, also check the valve on the kidney.
 
n&s were not closing all of the way. I had to bend the arm that opens it, This and the the coupler on the carbs had stripped out allen screws and was slipping. It seems like it is always simple stuff that i overlook when troubleshooting.
