It appears as I said, there is nowhere to mount the coil on the engine. The coil was mounted to part of the chain saw body. You'll need to fashion a way to mount the coil, (nearly impossible), or convert it to electronic ignition. It is also one of the newer smog engines with a two barrel carburetor. You'll need to fabricate a new manifold arrangement. Block off the upper, smaller hole on the intake manifold, and use only the lower one with your new carb. It appears as though your original carb has both high and low adjustment needles. If so, you could just go ahead and use it, but when you test run it make absolutely sure it will get rich enough, as those carbs are meant to run lean. I've seen a lot of these models burnt up because they run lean and hot.

rcextremepower.net/rcxpignitions.html has good prices on electronic ignitions, and it is a worthwhile upgrade. Less weight, easier starting, better idle and often more power. I don't run magneto engines; all mine get converted to electronic. It is also something to consider before purchasing your prop hub, as a prop hub for electronic ignition is configured to hold the sensor magnet and replace the magneto flywheel, instead of just taking place of the magneto nut in front of the magneto flywheel.

Nice pictures!

Edit: For some reason that link I gave you won't work. Try just typing it into your browser. I can access the page from my computer when I do that.
