hi guys. I really need help.. I have the above truck and strait out the box stuck... I'm using optimax 25% my problem started when I first started it up... started first time, great.. then I left it for about a tank and a half to warm and idle. sound started to deepen slightly but no matter. assumed it was normal. as soon as I touched the throttle it cut out. 4 hours later and many forums and phone calls later.. All I got was to try to lean the hsn in very small 1/8-1/4 incremeets. I leaned it by 1/8 of a turn give or take, the truck refused to start for over a hour it started when I swapped the plug but now won't continue running.... since I have returned it to "factory" which from a brief look on here was a bad idea!! please help as this was a Christmas present that I really don't wanna loose, I waited years to have it and now I'm old enough and I have it.. I'm worried I'm doing something wrong. oh and the msn? what on earth??
