Thanks!
I thought of making the linkage so that one TB is fully closed until 2/3 throttle like a 2 step carb. After 2/3 throttle resistance will be added to the CHT for enrichment. Up till 2/3 hopefully good MPG (IMG:style_emoticons/default/smile.gif) . /Lars S |

Being so far apart and only joined with a small hose, making them progressive isn't an option but it might work with your setup. The only downside I've noticed is a sensitivity to slight input changes at very light throttle settings. |
