hi all.i bought a stolen recovered 99 honda cg125.i put an ignition on it and it starts.thing is it will only idle at half choke.take choke off and it will die.even if i turn idle screw way up[reving high]it will still die with choke off.sounds like blocked pilot jet or air leak right?ive had carb off 4-5 times cleaned,replaced o rings,replaced pilot jet with another i had,sprayed around boots with carb cleaner to check for leaks[nothing]air filter is in good nick and well sealed.ive tried turning air/fuel mixture screw but it makes no difference as it wont idle without choke.it is set now at 2 turns out.im starting to think this bike was'nt stolen at all.anyone got any other suggestions?o im going to swap needle with an old one i have but im not confident as the needle on it looks ok.

Hi, apologies if I am mistaken but the choke on my CG (ES4 therefore a little later) is IMO counter intuitive (fully down is off; Fully up is choked; Midway will retain ignition), in my ignorance I suffered from the same 'fault', may I suggest that the first thing you try is 'choke lever up' (to combat lean running whatever the state of the engine) and immediately down (if the the engine stalls at this stage then simply delay the downward slope of the lever), leave to warm up whilst you don your togs and away you go. I have found that this procedure suits my engine's state of tune and have therefore capitulated. Best of luck john
