I need some help guys. I recieved my engine kit today (kingsmotors) I could not have been more excited. I get everything out examine it all and found out that the only installation instructions are the ones posted online. These are the same instructions I have been reading for two weeks thinking that they are just a brief run down so that you know what your getting yourself into. I nderstand that some basic mechanical skills are needed however when spending $300 on something I expect details. Either way I figured it out for the most part hopeing that I'm doing it right. There are just a few shady areas I needed a little help with. First how do I shorten the chain? Second I have cords coming out of the throttle (which I'm assuming is for the kill switch) and I have no clue where to attach the cords. One is red and one is black if that helps any. Thanks alot.
