If you're feeling rich, try some Lenkite Av-Blend, or Lycoming LW-16702.
I've seen the Lenkite work on P&W stuck valves after marvel and WD-40

    I have a gun-nut world class pistol shooter pal who says Hoppe's #9
ain't what it used to be.  The EPA or somebody made them change the

formula,

and they had to hire perfume makers to recreate the old scent.
According to my source the serious firearms types now use something

called

Break Free, available at gun shops.  You might be achieving a first

using it

on an aircraft engine.  It works better than Hoppe's on my pistols and
rifles.  Good luck.  Tom Mayer

  Thanks for the suggestion, Tom.

       I did purchase some of the Hoppe's #9.  Its a quite heavy, oil low
viscosity but claims its a penatrator, the two characteristics seem
contradictory. I could not tell that it worked any better or as well as WD-40,
perhaps for the reason you mentioned.  I'll see if my local gun shop stocks
Break-Free.

    I'll also check with an A&P friend and see if he has any of the Lenkite
or LW.  By the way, I am having some success.  I freed all the Front Rotor
seals and two of the rear rotor seals.  I actually fired up the engine and
it ran - although shaking like a hippo in a disco - with the rear rotor not
carrying its share of the load.  It looks like I have one apex seal still
stuck, so if Lenkite or the LW 16702 can free it will be worth the price.

Thanks again
