| I may be able to help you with the flywheel side of things. I will have to have a look through my bits and see if i still have it but i have a flywheel that i'd lightened and the pull starter let go and tore all the fins off. I'll have a look on Monday and let you know. You can have it but you will have to pay for postage.
In regards to your engine i think you've done a great job so far and it will be interesting to see how it performs. Are the cranks exactly 180 deg apposed to each other? The only problem i can see is that the timing on the "slave" or "second" cylinder may be out of ignition timing compared to the main one if the cranks aren't exactly opposite each other. You may need to put a mark on the cranks of both cylinders at TDC and use a timing light to set the ignition timing so they are identical.
A solution to the carby throttles may be to fit a pair of walbro's (even reps) and make up some sort of linkage system to the throttle arms. Either that or make a system like dual front brakes where the throttle pulls both cables at the same time.
Cheers Gabe
