Hi Garrick,
Wow now this is a hard call.
There are lots of questions without answers here, like, is the engine in running order if it had all the correct bits on it ? Why were the bits taken off in the first instance ? would this be a smokey engine if it had all its bits on it ? should you spend the time to find out or just replace the power plant altogether ?
Only you can answer these questions and it all is a matter of how much effort you want to put into it. Only once this last question is answered I can point you in the right direction.
One other thing you have to take into consideration, is because it's the smaller 14 inch machine you probably will be limited with what replacement engine you can use on it due to weight and physical size on the frame.
Cheers,
BB.
