CH sells the conversion kit - it is very easy to install. I'm sure if you sent them the engine they'd install it for a small charge. I believe RCign1 (Ralph) could do the same for you - installing his ignition system of course. You hear good things about the both of them. I installed a CH system. My personal findings are the change resulted in much easier starting and smoother running from idle through midrange. Fixed advance is crude but cheap, on the other hand it's also reliable, no extra cost and you don't have to charge batteries.
