What Zippi said is exactly right. But, I'd make a suggestion. If this is your first gasser, I'd get some help from somebody with experience. These gassers are a differnt animal. They have idiosrecricies and that can be problematic. Also I would FORSURE get an optic kill switch or choke kill or something that will help with stopping the engine. Again, gassers are different. Please get some help, or you may be sorry. Nobody wants that.

thanks
