Oko/kosso/keihin copy 26mm

Just built a 125 reedvalve motor...yes 125cc with a centre squish centre plug head. Scootopia clubman . I've set the timing at 17°btdc . I've not checked what was in the carb jet/needle wise ...just put it on and it fired up second kick ...it seems to run ok but would like peoples thoughts on jet and needle combos. I've never set up one of these carbs before hence asking on here .

Cheers Simon
