Powdered metal in engine
There is none inside the carb.It starts in the intake just below.We took the engine out and started from scratch.Honed vatted, cleaned and cleaned some more.Took the heads apart,valve job done,complete rebuild.Put the engine together Wednesday.It sat in the engine room till Friday night when we installed it.Cranked Saturday morning.It's was inside a machine shop the whole time.Never taken outside.There is enough metal to pile up on the pistons and lock them against the heads.There is nothing on top of the engine to be a source.No hood or air cleaner.Could it pull that much metal from rusty headers?We thought it was cylinder wall rust the first time.There is no way it could be the second time.
