Matt, do you have a link for the exact Teflon material you are using for your coupler?
I want to include the link in the ''Cookbook'' post so that the Teflon option is also available in a common location.
Just for the heck of it, the last couple of times I've flown I have used the electric starter for the first start of the day, without using the choke. Starts up fine after a couple of seconds, with subseqent hand starts the usual one- or two-flip affair. With the no-choke option available, it is obviously a viable option to use a simple carb stack (venturi) without having to use the choke plate, or looking for some ingenious way around it.
It's McMaster Carr item 5033K43; 7/8" ID X 1" OD (1/16" wall).
It fits the parts we require just about right....needs slight push over the button heads but that's all. Material should have a good spring clamp over it that produces good 360 degree contact for a decent seal. BUT as discussed before, one should not use worm-gear clamps or any type clamp that will distort the pipes underneath.
I've used a starter also before, for what's worth. I don't like them....they scratch the spinner finish. On the other hand, I am not thrilled with the baffle choke arrangement of the carb. I am working on a carb inlet solution around the baffle choke that will enable easier intake muffling.
