hey guys im selling my 2004 blaster because its been sitting in my garage. so im trying to get it back in full working/perfect condition. im having a problem getting it started so i jumped it off from behind the truck and as long as the truck was pulling it, it ran but never went any faster then it was being pulled . once it was under its own power it would die. is this a carb issue im assuming. but anyone have any ideas/ comments?
