Yes to the common carb problem, but it also has to deal with 3:07 gears with 33" tires. I know, because it was me that had all the problems. I am also getting a ton of ignition/fuel problems on flat ground while accelerating now, so i am going to begin with the filter, & de-bug my fuel supply. If that fails, i will do the ignition etc, etc, etc. Blue Yellow runs a carb with almost zero problems, but he's tuned for climbing & has 4:56s. to sum it up, carbs are ok, but if you have the cash & are building from scratch, go with FI.
