How much ignition timing does an ARDUN engine run on the dyno?

Asked how much timing these are normally run with, the answer is 26, and you can go to 28 if it needs more, but it depends. Reading the plug, it is down on the ground strap pretty far. A couple more degrees does not really make much; it kills it more than it helps it, and 26 is safer, which is called the key.
