In reply to # 1509803 by GeorgeOhr The manifold arrived today and looks like it was machined by a drunken monkey. Carb mount holes drilled off center and canted where the carb won't seat or line up with ports correctly, carb flange wasn't machined completely flat and stray milling marks on top of manifold. I could clean up some of the cosmetic stuff but the studs and port matching work required is way beyond an acceptable limit.
I feel your pain.
Stuff like that just isn't right, and it pisses me off.
But consider doing whatever moves your project ahead, at least delay, inconvenience, and cost.
Machining is a commodity available anywhere and anytime.
That specific casting OTOH, no matter how absurdly machined, is uncommon and inconvenient to replace.
Certainly raise cain with the vendor, and see what they are willing to do to make it right.
But if they are not helpful, the pragmatic thing might be to just fix it and use it.
