Lol well I'm not 100% sure yet, I put it on and put the carb on and have had a couple issues. Put the carb on and my truck fired up and sounded mean, went to start it an hour later and couldn't get it to fire. It was a used carb so I was guessing the float bowls were full of some crap and clogged something up. I'll have it running soon and let you know how it runs with it.
