I think some are missing the mark on the oil pressure filter thing..the oil pressure that is read on these B and C engines is not relative to the actual pressure going to the camshaft and then to the bearings.. only 1/6 of the volume of the pump is going to the oil filter, head and govenor, by way of a tee fitting off the pump, and up through external plumbing...the restiction of the filter DOES make a difference in the READING of the oil pressure gauge because the oil gauge is in this external oil curcuit, the more restiction , the less (readable) pressure...5/6 of the volume is going directly to the cam and internal bearings, and there in no way to read this pressure ( in other words the oil pressure gauge is mounted in a lousy spot)...the oil pump relief spring is supposed to by-pass at 15lbs., there-fore always delivering around 14-15lbs to the internals of the engine, reguardless of what the pressure gauge reads....a serious resriction in the oil filter would starve the head and governor only
