Mike/All
That would be interesting to have a engine spread sheet but many would be unsuitable for our Kolb use.
Generally speaking auto engines are too heavy and powerful for Kolb use. Generator engines (Genrec and Onan) would seem to fit as options because they are designed to run under heavy load but are normally a bit heavy for the power they produce.
I really like the concept of the Yamaha that Jason is working with. After all Rotax originally modified snowmobile engines for aircraft use. The biggest problem would be a supply issue for wide spread usage. Not just engines but redrives also. Rotax doesn't like people using their redrive on other engines.
The R series BMW is another engine that shows promise.
I concur with Jason that there is a bunch of work in converting engines to aircraft use especially if you are the first.
New VW engines are available in unlimited quantities at very reasonable prices for Kolb usage. Parts for maintenance are also very inexpensive and available for the foreseeable future. The VW redrives are also available and continue to evolve. Granted a gear redrive would seem to be better and maybe a suitable one will be developed if there is enough demand. For the time being the Valley belt redrive is a good solution. One of the advantages of a VW conversion is that Great Planes will put together a fairly complete engine package and Valley will even build a complete "firewall forward" that you can test fly at their factory. To my knowledge no one makes a off the shelf exhaust systems but Larry Smith at Valley promised me they would offer them if there was demand. Also Kolb will build VW engine mounts on your new Kolb or weld on mounts for your existing Kolb. There are two more VW powered Kolb MKIIIs getting close to flying. The VW experiment is getting more refined so the effort for the next builders will be greatly reduced.
I will be flying my VW powered Kolb MKIIIC to Sun-N-Fun this year and camping with it all week

Hello gang....FWIW....I have 99. 2 hrs of absolutely trouble free hrs on my A-2200 Jabiru engine...I get 1000-1100 fpm climb on my M3X...it is smooth as silk...3-4 gph fuel burn...and basically maintenance free...I change oil and filter every 25 hrs and other that the the first few required adjustments at the beginning,that has been it. No monkey business mounting it or re-drives...just put it on and prop it...
Just my 2 cents worth...Hope to see some of you guys this summer !

Yes I forget about the Jabiru.
I'm relocating to the Oceana County Airport C04 when I return to Michigan
this spring. I will make a point to stop in to see you this summer. Looks
like you are about a hour away.
Maybe we could have a small Kolb flyin this summer. Get Steve S, Jim S, Ted
W, and you to fly over (also any one else that wants to join us). We could
start a annual fly the sand dunes and Lake Michigan shore line.
