Rat Bastid I run an Ice Ignition system on my 410 in Australia .It was very pricey but is a fabulous system with rev limmit and advance curves by the touch 0f a button and is a 8 amp system. I run 20 degrees at idle with 14 degrees advance for 34 total. We can have total advance to come in at 2500 or 3500 revs.The control box is mounted on my console for quick changes.
