Doing the white spacer mod.   It appears there’s an e-clip with about 7 positions.  What position should the clip be?

Also couldn’t I just put the clip in a lower position and then there’s no need to remove the white spacer?

Or, maybe I don’t have OEM parts.

Thanks.  It’s a Mikuni CV but the previous owner must’ve installed this different jet needle.  

Does the proper needle only have one groove for the e-clip like in this photo?
