Hi folks. I have a combustion motor that is going bad. I have done the searches fo a replacement on this site. I used the links offered but they seem to want to sell the Fasco A082 which appears to be longer than will fit in the stove therefor not allowing the access panel to be reinstalled. The installed length the motor sticks out of my housing about 3.5 inches. The fasco is 3.800 long per the sites. The factory part # I need starts out 50-473, updated to 50-901. The linked sites also list # EF161 or EF 161A. I can't find a crossover for this number to the FS model. My question is does anyone know what will properly fit the FS model? Thanks in advance.
