Ok...so i have been building my 2 for the past two years. i have put tons into to it trying to get it to run, and have run out of ideas!! so my problem is that, well first it wont start. i had gotten it to start about a mounth ago after cranking it for like 15-20 min and it ran on two cylinders reving up, but then when u let off it would hit 4 commin back down, and sounded exactly how it did when it was running right.. then when u would accel again it would be on 4 for like eight hundred R
