i have a question. im planning on getting one of the sts .21 engines for my buggy. i plan on using 30% fuel for it. when i am breaking it in, should i just leave only the silver shim in since i will be breaking it in with 30% or leave them all in till the break in is done?
Hey redfox03 if you follow my instructions a couple posts up you should be
in good shape. Keep all shims in place till you reach 3/4 a gallon ect. Linkadrip
is correct in that the shims are in place to lower compression for break in. Hope this helps!
