Upon dis-assembly of my 51 216 thriftmaster I noticed that the oil passages through the rocker shaft were plugged up with slugg, after cleaning I noticed that the shaft could be installed with it's oil ports positioned up (towards the rocker arm oil holes)or down. The manual does not specify, it only mentions that the shaft plugged ends are away from the rocker arm oil connector.
Anybody know which is the correct position of these oiler holes?
Thanx
