So I recieved my new 34cc OBR engine yesterday with a WB-1107 carb. I e-mailed them for the carb settings. The low should be set at 1 1/8th turns the High should be set at 1 3/4 turns. When I bought the Rovan it has a 36cc with a WB-1107 . Recommended settings1 1/8 low and 2 3/4 turns high. Wonder why the Rovan motor is run so rich ? This is along with a 25:1 fuel ratio where as the OBR is 28:1 for the fuel .
