Oh yeah I forgot about the battery, I just held mine in place with some zip ties and it sort of works. If the mounting holes on the new carb don't line up you can either drill new ones or widen them a bit with a small file. As for tuning I found a good guide for mikuni carbs but it should apply to the molkt carb aswell. http://walbro.com/brochurefiles/3368...g%20Manual.pdf

If you get it working right I'd love to know the results.
