[Healeys] loose tricarb throttle lever

[bstarke at telus.net]

Hi everyone, I need some advice. The front throttle lever on my  tricarb--the
carb coupling shaft--has a little play ( the rod moves relative to the
vertical flat part). The rear one is tight. What is the easiest/most effective
way to remedy this? I have thought of solder/spot weld/JB weld--what will
work?
By  the way,  I have the carbs removed/balance tube off /linkages
disassembled, so I have the piece loose for easy repair
Thanks
