Some folks use the OPTI-2 @ 100:1. Choise is yours, but 20:1 is too much IMO. Looking forward to seeing your build.
MAc - thanks! - I've noticed that it's been staggering a bit and wanted to know why. Guess rich mix may be it. I'll lean up the mix a bit ( a tank at 40:1, tank at 60:1 etc.) and see where the bike likes to run. I use Homelite synthetic and it works, well, OK I guess.
