: Any helpful hints on rebuilding the heat riser, specifically pulling the shaft to free the counterweight, washer, spring and butterfly valve? Seems like the counterweight and butterfly valve are not included in the rebuild kit and need to be removed without destroying them.

DW, My heat riser control was totally rusted in my 48 cj2a. The butterfly was spot welded to the shaft, so I ground the spot welds off then had to drill both sides of the shaft out and remove the butterfly from the remaining piece of shaft. I bought a long bolt of shaft size and hacksawed a slot in the end for the bimetal spring and after rassembly, anchored the butterfly to the shaft by drilling the shaft and butterfly and using a split pin. It works. Every repair is a new adventure. Good luck
