Yes the mid range is a bit rich. The Fox really needs a HOT LONG plug and a tweak or two on the low speed needle. I was using an OS #6.

I think it needs a HOT LONG plug because I tried a Fox Miracle plug a while ago (which is a long medium heat plug) and the mid range improved greatly, but it did not idle as well and the top end was less than when I used the OS plug.

So the combination of long and hot should fix everything.</p>
