Johnny: I had the same problem with my chute. The easiest way I found so far is man's best friend...
Duct tape! It's shiny and slippery and is applied really fast.
I did however take the chute off, use a wire brush on a drill to buff it up, and applied a new coat of spray paint to get better adhesion. Worked like a champ.
Have you tossed the H70 yet? Mine is an H80 and the carbs may be the same. I'll find out. If you are interested in selling the carb (just in case, touch wood) let me know. I'm just down in the TO area. Mine just popped the intake valve spring retainer. Looks like I'm shovelling until a new part arrives...approx 1 month.
