Driving my '71 Fiat 500F the other day, I heard the sound of something falling off the engine and bouncing it’s way through the engine compartment to the asphalt below. I stopped and couldn’t find anything obviously amiss and since the engine was still running nicely, I just carried on my way.
It wasn’t until a few days later that I found the missing bit: the forward stud that holds the air intake pipe elbow to the top of the carburetor (26IMB10). Before ordering a replacement, I checked the threads in the carby top. As I suspected the threads were mostly gone and could not hold an M6 bolt even with Loctite.
So, what's the best way to go about installing a new stud. Should I tap the hole out and apply a Helicoil? Has anybody got another fix for this problem?
