A buddy of mine just picked up an ebay valve, put it in his promaster.. the thing started pissing air out the barrel. Long 'n short of it...the milling on the valve stem was bad; the valve stem STUCK full open in the marker (yes, I know, it sounds insane).
His marker is on the way to Vaporworks for a vapor valve and a tune-up to address the problem that prompted him to buy an ebay valve in the first place.
