I went through the same thing and cured it with a new MP distributor.

BTW, I just put the same Summit fan (18" version) for the same reason.
GOOD flex fans rock!


Thanks. This distributor is brand new. FWIW, I have had it for years, and didn't pay near what it is going for now.

I had another thread on what I did to curve it over the weekend.

Agree on the fan -- this thing is really nicely made. Very pleased so far.
