Actually, it's now owned by Ken & Lorraine Morris. More info here:

An updated page in the "Resources" section of the Web Site should be available shortly.

Ok, thanks!

Not sure how it works, if theirs covers this or not, but when mine was done in 1980 they used the 150 setup that pulls heat off both sides... I know our gals have a reputation for low heat output... Mine with that set-up will cook you out...

Lorraine got right back to me and she has sent the STC. I'm planning on using the Wag-Aero kit https://www.wagaero.com/engine-parts/ex ... stems.html When I get around to doing the conversion. Although I have not seen the STC paperwork yet it looks to me like the one scat hose goes to the heater from one side and the other goes to the carb heat from the other side.

This may be a redundant question but I need to be sure...This will fit on my O-200-A right?

All C-series Continentals, including the O200, and I believe, all A-series Continentals, have the same exhaust port spacing.

Hello Raymond,
Curious if the carb heat is shared with cabin heat on one side?

I would like to add a solution to a problem I had on my 0-200 exhaust installation. The baffling aluminum sheet wrapped around the mufflers have the clamping angle riveted to it. The thin aluminum would become deformed and the rivets would pull. I added a doubler under the angle that extended a couple inches around that baffling. I think these were obtained from Wag-Aero.


I might find a good photo of this and will post it.
