My scoot is now starting first time and running nice it would seem. It is starting first time from cold BUT without the choke being engaged. The choke is seating ok. Could it be the mixture screw is too far out, I am starting it with the throttle closed.
Thank you in anticipation.

It's a while since I have had a Keihin but I think it is out to lean the mix as the screw is in front of the slide?

Logically, if it starts without choke you are too rich at start up so you may want to lean the mixture screw or consider a weaker pilot.

I have been as low as 32 pilot on that carb. Found it very difficult above 34 pilot.

Chris can you elaborate on the problems you had above 34. Mine is a 225, Scootopia Ancilotti Clubman fitted.

It 4 stroked as you pulled away.

Thanks for that, I have sizes 32 to 44, will tinker Sunday, I have just been respraying my re-bent stand. It now misses the new exhaust, job done.

ive used this as i guide to jet mine , started straight up but couldnt get it to tick over without the choke as it was too low !! went to adjust the tickover as it was low and the bloody tickover screw snapped
but check out the varients people have used

Nice on Daniel, thanks.

Chris in Margate. I pulled the pilot out today SIZE 40. No wonder it started without the choke from cold. I have fitted a 34 and will test it tomorrow when the insurance starts. Just got ripped off by Bikesure for a change of vehicle.
