GRP Engine Factory Needle Settings

[Nitro Nut44]

Can anyone tell me what the factory needle settings for the .21 and .28 Off Road Tuned line are? I can't seem to find it in any manuals. I rebuilt a couple and want to go through the break in procedure.
Thanks!

Basically flush with the housings for both.

It's not flush

.045 inches is not flush. Get a digital caliper. I found one for $30.

.045 is actually, near as damnit a rizzla paper folded over onto itself. Basically, so that the rizzla is like a 4 ply tissue.

a rizzla is 1 thou thick when un-folded (an old engineering bit of know how i learnt a looooong time ago). half a thou is virtually nothing so it wouldnt matter too much if you are a half thou out.
