Hi all,
Any chance anyone knows what shims are used on the spark advancer mechanism. All the ones in mine are in bad/non-useable shape. Not listed as individual parts in CSMNL.
Rather not have buy a whole unit.

Looking at the crankshaft bearing shells, couple of them look in poor condition - recommended that if replacing a couple might as well replace them all?
For curiosity, these are marked with D4I-A STD and such, but nothing comes up in Google? Thought it maybe was a part number?
Oddjob:
The numbers are batch codes, they are normally useless unless you can see the colour still on the side of the shell in which case it's logical to assume that all shells with the batch code on are the same colour.
One's pretty bad, hows the crank journal on that shell location?

Yeah colours are gone on the shells.
I'll take a photo and post it for a second opinion. And I'll take a closer look but on first inspection the crank journals looked OK. Didn't notice anything obvious as the condition of the shells and I didn't feel gouges running a fingernail over the surface.
