SR3 with 2 holes

[AjW]

Hey there,

 

Every now and then I have a root around the engine to try solve the problem of low power at high revs. Along the way I cleaned out the fuel pump housing and noticed that there are 2 un-bunged holes at no.3 fuel pump. Are they supposed to open?

Yes - its for fuel/oil to drain down into the crankcase

No - which explains why oil leaked from the fuel pump house under higher revs

 

Here's a pic - black circles show grommeted holes, blue circles show un-grommeted holes

 

Any ideas?

Yes, it's the oil drain
