I recently approached my friend and co-owner of my Mk 3 about my desire to upgrade
to a used 912 to improve our take-off performance. Due to his busy business
schedule, he has only rode in the Kolb twice with me in the 10 years it has
been in operation, and only participated in the construction as a financial partner.
I did 100% of the build and also hanger and fly it from my home.
Not surprisingly he asked instead if I was interested in buying him out. Of course
I am, but this unexpected expense, as well as doubling of my share of a new
engine has eliminated any chance of me affording a 912 setup any time soon.
Enter plan B.
Have decided to build a 670cc Rotax sled engine into an 85hp aircraft engine.
I'll be relying on Rotax Rick to do the bottom end as there is extensive machine
work on the PTO end of the crankshaft as well as the cases to make it work with
the aircraft gearbox and to fit the 582 ceramic water pump seal. The top end
and cooling system I'll handle.
Will also be using Ricks 618 style exhaust to insure the power delivery is smoothed
out for our application.
Also helping to make this a more affordable installation is the ability to use
the same prop from my current engine as well as all the probes and EIS unit. Additionally
I'll also use two of the three Bing carbs from my 2SI engine as I
swapped them out for 28mm Mikunis a couple years ago. Should be a very straight
forward swap, and using the same prop is going to make it clear how much more
power the new engine has over my 690.
My 690 has been a 'SMOOTH', solid engine and performs fine other than the gearbox
being incessantly leaky, but flying out of my 600 foot strip in the middle
of the woods makes me desire more climb performance.
The engine core is on it's way from a sled salvage outfit as I type.
Let the discussion commence.

I can feel your pain for the lousy partnership in your Kolb. I went through the
same situation with a partner. Building an aircraft with a partner does not
work, does not work.....will never do it again....

Guys,
Didn't mean to give the impression I have been unhappy with my Kolb co-owner. Even
though I did all the building and maintenance, I enjoyed it and since it was
my third aircraft build, I had strong ideas of how I wanted to do things. Also
basing it at my home made it seem like I was the sole owner. since I was
doing all the flying anyway, I haven't even asked him for any $ toward upgrades
such as the carb conversion and other upgrades I've done. Which means my buy
out cost has not gone up in 6 years :-)
Jay was a low maintenance partner. Also was nice to have only half the financial
burden during that building period when money was tight. I am blessed to have
at least four friends who I wouldn't hesitate to partner in an airplane with.
In fact two of them are my current partners in our 1948 Cessna 170 project and
my outgoing Kolb partner Jay Swager is another. You meet the nicest people
at airports.

Dennis,
Good luck with your 670 build. I know Rick real well, and I am sure he will
do a good job doing the Machine work for you. I have two 670's myself, but I have
decided that a Rotax 618 has plenty of enough ponies for my Firestar II
The 618 I have needs to be rebuilt and I plan on having Rick do the work for me.
I was real lucky this summer to find a Brand New 618 exhaust on E-Bay, it has
never been used. I also plan on letting Rick doing a 670 for me as I plan to
have a Two Place side by side one day. Hopefully it will be a Mark III Extra
or a stretched avid flyer.
Anyway keep us informed on your Progress

Just some info that some may not know. All 670's that Rotax made are not a good
candidate's to be converted for aviation use. That is if you want Dual Ignition.
and some are not easily made to be provision 8. Their are 2 years that are
preferred the 93 and 94 model year. If the 670 has a black rubber cover on the
Mag end then you will not be able to have it become Dual Ignition
Many people think that Rotax was planning on making the 670 into an aviation engine
like they did with the 617 that became a 618. If they did it would have been
competition for the 912.
here is a picture of the early model PTO end, that can be made to accept a
c-box or e-box. you could even use a b-box but I think it would not hold up to
all the extra HP
