After visiting 7, count them, 7 shops that supposedly service radiators, I found an old school radiator guy that fixed my leaking throttle plate heater (I have a beta version with the soldered top). There aren't many of these guys around anymore. Preheated the assy, used a high mass iron that looks like something from Fred Flintstone, and did a great job, overnight in this case. I have no interest in this company other than being a satisfied customer. Turns out he is a sponsor of the huge Patriot Place cruise on alternate Thursdays, and everyone but me already knew about him.
