Got my kingpin back yesterday, runs great again. Problem I was having was around town, it would not run at a steady rpm without surging, coughing, and jerking. they replaced the intake gasket, showed me where it wasn't seated properly and said it sucked air making it run lean and low pressure on fuel pump, He talked to rylan and replaced the pump with a walbro pump from quantum. Gave me the old one, but since I am not the original owner, I am not 100% certain it was the original pump. Anyway he replaced it and it runs fine.
