My 2818-1 was leaking fuel pretty badly from the front bowl and i discovered that the bottom screws threads were stripped. I dont recall this being an issue the last time i rebuilt the carburetor, but perhaps when i had it in for a tune up, they were overtightened and the threads stripped out. I thought i was going to need to replace the throttle body, but then discovered threadserts. It took me all of about 10 minutes to drill, bevel, tap, and install the threadserts into the two bottom screw holes. What a great invention!!!
Here are some pictures. I thought i would share just in case anybody else has encountered the same problem. It seems like it would be fairly easy to strip the threads over the course of many rebuilds.
Threadsert installed No more leaks and the original 2818-1 is saved
Been there, done that. My Holley started leaking from the bowl screw awhile ago, and I discovered the bottom screws were stripped. Sure surprised me since nobody had touched the carb in at least six months, and all of a sudden it has stripped screws. Only the bottom bowl screws -- is this modern gas eating the threads? Anyway, like you I found the threadsert kit (or helicoil, to some of us oldtimers), and was able to fix it right up.
