not sure what size these are myself.i have a couple of them and also a powertorque one. there is as i emember a good post somewhere about them as i researched when i first got mine.
after a bit of fiddling i got all 3 going good.
they are worth keeping tiztom and not too difficult once you start playing around with it. theres plenty of info on this site about all aspects of carbs etc so do a lot of searching ,i am sure you wont be dissapointed.
i will do a bit of searching myself for you and get back to this. ive been using this site for years and still cant find stuff??
