Yes....2% is far too much...might cause pre-ignition.
Occasionally I have started an engine without a battery at contests to distract competitors.....only 1/2 ounce is plenty.
Depending on the fuel and plug....acetone can improve the idle too.
Downunder will be popping up soon to repeat what I just said....LOL...
