Shakedown, no breakdown... yet

Oh yeah heat melted nylocs, I thought there was a reason I didn't use em near hot stuff. Air craft supply are helpful for the crimp locks in high grade.

I think its a disservice to keep harping on the myth not to nip up the carb flange
good and be done with em. The O ring seal is an engineering joker sucker punch to foul up the most careful owners. Even if ya get them torqued just right, as the Amals heat and vibe to a blur the soft flanges distort and nut tension is lost then air let in and nuts are lost.

I've no more carb fastening issues after I put a real gasket between carb and manifold and nip up nuts as much as they can take, w/o locktite so they back right off again once the binding torque is released. Its piss ant tiny bites enough to work nuts w/o the drag of locktite grit. Thick paper, composite or cushy silicon or rubber works a treat.

I'm still following the myth and it seems to be working for me. O-rings, plain nuts, blue loctite, nip them down just enough to flatten the lockwashers. I haven't had any carbs fall off since I started doing that, the carb bodies haven't warped, and the manifold heat has not been enough to release the loctite. No loctite on those allen screws for me, just some antiseize. Those screws are hard enough to remove without loctite, I can't imagine what a PITA it would be if they were all loctited in place.

But, ask ten Norton owners and you'll get ten different answers! Whatever works for you I guess.
