CONGRATS!!!!!!!!!!!!!!!!
things break... make sure you don't have any sharp corners and it should not break the second time.
With the vapor carb, once it is a perfect mixture it revs wide open, you can either lean it out or enrichen it to slow it back down. The lean option is a little less sensitive but makes the motor run hotter.
now you know what you are looking for and can start to feel what the motor is asking you for. You have done something very few people would or could do, you have created life!
Make some parts and get some video... a long one so we can see the fruits of your labor, and oh, take your wife out to dinner... it will help!

Haha! Thanks guys, yes, it is interesting as to why the revs climbed so high and so quickly!
To be honest, I'm not surprised the con rod broke, the wall of the big end was far too thin once I'd opened it out so that the bearing could be inserted. Hopefully I'll make a new one tomorrow and get it running again! I was quite shocked how hot it got!!

Yeah, when you think about it, the throttle is wide open because there isn't one! I think I've seen somebody successfully added a throttle with a vapour carb to control the speed.
