I ordered a B&S 1100 Intek today. It does not come with a adjustable throttle carb. I was thinking of putting a dirt bike carb on it (fab up an adapter). Has anyone ever done this? What size carb would be appropriate? I have a carb off an XR250 (same displacement as the B&S). Or does anyone have any suggestions of a B&S carb or the likes to bolt on? Thanks for any and all input!
