So I finally got around to pulling the carbs and I found that the PTO carb was loose. It appears i might have overtightened the bolts and they were sloppy. I found that the thread inserts were junk at the end of the holes. I performed a pop off test on the carbs and they are 32 and 30 psi. I installed some longer bolts in the carb with washers and tourqed to 15ftlbs. It feels solid now and I'll run it on the trailer on Sunday. It will be a bit before I get it beak in the ocean. I'll provide an update then.
