go to massive mods web site and order one. or fx racing hobbies in canada my have one, also racer22 is a dealer he may have one. I usually just go to massive mods. back ordering some times means they will have a new engine out before you get the parts. They go fast. If you can afford it order 2 of each if you plan on running go-tec's for any amount of time. as far as cold, if I cannot get a heat gun going at the track I will leave the glow igniter on for a minute, then easy rev's for about another 2 minutes. then it's easy driving till it's warmed up. You can always tell when it's warmed up, it all of a sudden comes to life.
