Craftsman 42cc Chainsaw Motor and Magneto Mount for RC Boat

I have been working on a RC Boat project where I am attempting to stuff a Craftsman 42 cc chainsaw motor into a 3 foot long wood fiberglass RC boat hull. The problem with a Craftsman chainsaw, is the magneto mounts into the casing of the chainsaw instead of to the block like most two-strokes. I had to design a motor and magneto mount so that the motor would run. There was not room for the body of the chainsaw in the boat. It has been quite a challenge to design a mounting system that fit in the space requirements and still held up to the forces the magneto and block withstand. I am using PLA for this build as it is easy to work with and should be strong enough for this application.
