My atc 110 has just had a new carb, but i thinks something wrong. Before, i started it, and i instantly got lots of white smoke, and a very loud sound. I think the carb i put in had been fiddled with, what are the correct settings for the screws? I'm thinking the noise might be the new exhaust i just put on, but i'm not sure, i stopped thengine pretty much straight away. Would the white smoke indicate water has got in, and its just evaporating? Anyway i cant start it not, but i seem to have a spark. The spark looks an orange/redish colour i think. shouldnt it be blue? Why would it be reluctant to start all the time? and finally, when i start it cold, should the choke be 'open' of 'closed' ? When it did the loud noise and smoke thing, it started stuttering, and it did that thing when i flipped the choke lever. Any help is gratefully recived.

 

have you tried to push start it?
as for as the carb goes turn the idle screw all the way in and with it idling
slowly back the screw out til it has a nice smooth idle i think its about 1&1/2 to 2 turns out
white smock means too much gas not enough air common after you change the carb
it should work itself out
cold start choke should be on or 'closed'
cant help you on the orange spark
remember always have fun
half the joy of owning an old trike is keeping running w/ your own 2 hands IMO
