Having built both of my KRs from existing projects where the spars were already built, I cannot tell you what I used to build them, but from what I have read, and what I have used to bond other wood structures in the plane, I suggest T-88. I am offering this as I see you have had no other responses.
I have a question about bonding where filler is needed. I have taken the header tank out of the Black Bird, and where it was bonded to the shelf, with way too much flox, some of the plywood laminate pulled up with the flox. I was going to use T-88 here, but want to know if when using filler, it is better to bond using the epoxy. I use AeroPoxy for my glass parts. I am now in the process of changing out my VW engine for my new Corvair engine that Roy built for me. I also had concerns about how to mount it, but if you buy the KR motor mount from William Wynne, then it will almost place itself on the firewall. I know this because I built a mock firewall from the KR plans, and it went right in place, even the William Wynne cowling fit properly, front to back. It will take a little trimming because it is made for a KR2S which is a little wider, but is very flexible and should be very easy to make fit.
