Just a quick note to say the aluminum brazing didn't hold up.[>:] I don't think the propane torch was getting the pores of the parent metal enough heat to open up and accept the filler rod. The filler rod was barely clinging to the case after running the engine a few times. I did as good a job as I could to clean the repair site, and now it's up to JB WELD to see if the patient will live.[]
