So which shim are you guys calling the extra shim???

Mine only has 2 shims, 1 thin and 1 thick (i assume .1 and .2mm). It's been that way from day one running 25%-30% nitro with temps usually in the 190-230 range and i've got about 4 gal on it now..

I don't remember Russ ever saying to remove one after break in before But i think I remember someone saying before that shimming should be in the .6mm range...So more than anything i'm confused as hell now..
