Hi guys - the rubber air intake temperature control flap on my air cleaner is loose to the point that I can set the flap for the cold-weather position (needed now that it's getting colder here in NC), but within a couple of minutes of vibration with the engine running, the flap will flop open to the warm-weather position. It looks like, over time, the rubber flap may have contracted just enough that the portion surrounding the metal temp control lever shaft is no longer a snug fit between the two sides of the sheet-metal intake snoot of the air cleaner.
I'm contemplating eliminating the slack by cutting a slot into one side of a small flat washer and jamming the washer between the flap's pivot (and around the metal handle shaft) on one side and the adjacent side of the intake snoot. Another option, I suppose, would be to squeeze the two sides of the intake snoot together with a large pair of vice grips just enough to re-establish mechanical tension between the snoot and the rubber flap. But before I do either of these things, I wanted to check and see if anyone on the list has dealt with this sort of problem in a better way.
Thanks in advance,
Richard
