I was looking at the oil pump pick up on my 261 to day and at the bottom center there is a very neat 3/8" dia. hole in the screen. Now I'm thinking why have the screen with a 3/8" hole in it or is the hole isolated from the screen area? Maybe there was a plug there that fell out? I looked at the online manual but couldn't find a close up picture of this detail, Can someone help me out with this ?
