Since there is more interest in the 20B than expected,  we will be

a 20B overhaul kit in addition to the currently available 13B

kits.  Will

put it on our website as soon as it's ready.

Paul, has anyone actually used the TES Oil seal O-rings in an

operating

engine (car or airplane) yet?  They look good on paper but I am

hesitant to

offer them until they have actually been tried.  I'm working witrh

someone

who is planning on using them but engine run is still months away.

The Viton O-rings now included in our kits are more heat resistant

than

stock and have been well tested.  The TES version could be even

better so

will include them when tested.

Chuck has a set but has not installed his new engine yet. I would

not

worry about it at all. I see absolutely no show stoppers on this.

Nothing

but advantages. Unlike the stock oil O-rings they won't go away if
you overheat the oil.

Having said that and be that as it may it is no big deal if they

don't

work perfectly. So it leaks a bit of oil on start up. I ran my 76

Cosmo for

years (10 or more) with a big cloud of oil smoke on start up. No

worse

than a radial engine.

Tracy,

Some of us will want 1/2 13B kits for single rotors, also. Maybe if

the single

rotor buyers = 20B buyers you can come out even (:>}. Or maybe you

should just

sell them as per rotor sets.

Thanks Fred,  My thought exactly, I was going to ask the same question.

We only need almost half a kit, with the exception of the main oil seals and
a few gaskets.

Tom Webber.

OK, we'll do the one rotor kits at the same time as the 20B.  Check website
for availability.

Thanks a bunch for doing this Tracy. IMHO the TES O-rings are a great incremental
improvement in the durability and reliability of the wankel rotary.
I think Mazda ought to do it too. God know enough people screw up
and overheat their street cars too,
