Hi berger,
Yes, that would confirm my conversation with the BSA mechanic a few years ago.
He said very similar to you. He also quoted his experience of folks fitting incorrect Goldie bolts with much bigger oil holes in mistaken attempts to maximise rocker oil flow then causing over oiling problems.
Once I get my engine working as its suposed to I am going to try the old bolts just as a test to see what happens. Then I can pass on the results to all.
Cheers,
Dan.
