I agree, If its not red , heating does nothing. You've really got nothing to lose. You should watch Fred Carlton take one apart on the carburetors and carbohydrates video, it'll make a Zenith expert out of you. I haven't hesitated to heat and quench since watching it and they never fail to come apart easily. Sometimes it helps to slightly tighten a stuck object and if it tightens the slightest bit it will usually then back out. good luck .
