I just finished rounding off the (brass plated?) nut that attaches the steel fuel line to the carb., once again. (repro assembly, likely made in China). Will now require vice-grip to remove/install it. I had heard somewhere that teflon tape NOT recommended for fuel line fittings, so a lot of torque was required to avoid gas leak when carb. last installed (two years). It was like the damn thing was welded in place! Would welcome suggestions so I don't ruin the next replacement nut/fuel line assembly (LockTite, anti-seize, putty, etc.?)
