How to tune a carb for hills? search didn\'t help! I have just gotten into real trail riding and hills/rock ledges and my carb is giving me fits. It runs great on the street and in the mud but get it on an incline and it dies. It is a holley 3110 with the dual metering block upgrade. I think the floats need adjusted from what I have read on other boards but want to hear what more people have done. I know carbs are not great on hills but have seen them work 10 times better than mine.
