Carb-airbox boots won't stay on?

[roy826]

Did you let the box cool completely before checking it for straightness? I had to do it a few times and stack more washers until that front wall of the air box was actually bowed out a bit. Then after it cooled it was straight despite looking convex while heating it with the stack of washers spreading it.

Basically I had to go past straight while forming it for it to end up perfectly straight after it was cooled and the washers removed. Kind of like bending a piece of metal you have to bend it past where you want it to end up. Hope I'm explaining it clearly.

But no matter, if you got all the boots to stay on it sounds like you got it close enough.

Yes I let it cool and it looked level on a table laid boots face down. It’s better than it was before but certainly not perfect. I checked for leaks with it running and none were found so it’s at least sealed up on the inside two cylinders now.

That's good. Probably not possible to get it perfect but the boots give a little margin for error. If it's not leaking then it sounds like you're good to go.
