Title: TAC shut-off flap
Post by: johnbendik on October 12, 2019, 03:21:31 PM

My Eagle is missing the vacuum actuated 'shut-off flap' at the base of the air cleaner snorkle.  I still have the vacuum actuator, but the dohickey inside the snorkel is completely gone.

I would like to get this working again, because I have to crank the engine a long time if it sits more than a day, and I think the problem is fuel is evaporating from the carb bowls.  Sealing off the snorkel throat when the engine is off should help with that.

I don't expect I'll be able to find the flap anywhere, but I would make one if I knew what it looks like.  The TSM does not show the stuff inside the snorkel.  My actuator terminates in a bent loop of wire about 3/4 " long, which I suppose hooks up to the flap mechanism.

Does anyone know of a good diagram or picture of the flap?  Or know where I can get one?

Thanks in advance,
JB

One photo is from inside the air box looking down the snorkel, one is looking into the snorkel towpaths air filter and the last is of the actuator mechanism.
Hope these help.

Thanks for the pics, Taylor.  They're just what I needed.

There's a chance that my original flap is wedged somewhere in the bottom of my engine bay (I think it might have fallen off months ago when I last removed my air cleaner).  I'm going to jack her up and make one last search of the undercarriage for the flap.  If I can't find it, I know enough now to make one.

Thanks again,
JB
