I just picked up my third one of these and am curious if changing clearances is advisable or even needed. Reason I asked is I printed out the exploded diagram for the T21-5M/2 and it shows two .30mm and one .10mm shim installed but with optional shims of .15, .20 and .25mm as "optional". Since I'll be running 50% nitro in sport boats, do I need to change anything? I haven't checked the actual clearances yet but can if needed for clarification
Thanks
