Single turbo 360

Got to work on car for labor day weekend and got a lot done. Relocated battery,installed tank,fuel system,intake and carb, reinstalled piping and turbo after powder coating,exhaust wrap,boost and afr gauge,msd 6btm, and cranked it up. Still waiting on piping to finish cold side and mount bov. Afr is super rich at idle 10.9 and goes to 10 when throttle is opened. Any suggestions on timing? Distributor is locked. Carb is 600 dp with hanger 18 mods. 67 primary,78 secondary,29 primary squirter,35 secondary, and a 6.5 pv. Tried plugging pv but no change on idle afr. Needs exhaust . To loud for me. Have to look for a good muffler
