WHATS THE ORIGINAL SHIMING FOR THE 12-E?
AN WHAT ARE THE BASIC CARB SETINGS?
My .12 engine came with 0.3mm. I added extra 0.2mm for 25%nitro.
For basic carb, I suggest you rich the Main needle 1 full turn and then start leaning it as you go. Just make sure you still have smoke from the pipe all the way from 0 to full throttle when you trying at the stand, then do rest of the tunning at the track. hope this help
