CG125 will only run with no throttle

[Ingah]

Just to complete the story:

Fitted the new carb, gave it a test ride, got 4 miles down the road and just as i was filtering past a bus that was setting off from a set of traffic lights, the engine died.

Have you guessed what the symptoms were?

Oh yes, the same! (engine will start but use ANY throttle and it'll die).

I may have sworn a little this time

Anyway, decided to call the AA out because i didn't have all the tools required to strip the carb at the side of the road (was missing a screwdriver). That and there was a pub nearby, and i needed a strong drink

Anyway, with the help of the AA man's toolbox, we got it running.

THIS time, it was possibly/probably my fault this happened, as the bend of the U-shaped clip (which goes directly on-top of the "butterfly" shaped washer that holds the jet needle up) was in throttle-cable-side gap, so as the cable moved up and down, it probably rubbed against/knocked it, releasing the "butterfly" washer! (the carb came with the U-clip orientated like this; i'd been orientating it the other/more sensible way on previous occassions, but because i'd been having problems.. and it came like that.. i figured it would be safer to leave it as it was... Never trust the breaker to have it right!)

Anyway, cut a long story short (as it wasn't a simple task even then, we lost the U-clip and were looking for it for over half an hour! - and we also had to take the carb off again as the throttle wasn't returning...), AA man had liquid steel, the "butterfly" washer is not distorted/damaged and so clipped back into the groove nicely (groove number 4, as per the manual ) and now also has liquid steel holding it in place - forever!

So SOLVED (and the bike now runs just fine).

And i've ordered me some liquid steel as the guy was really raving about how good it is (known as chemical metal in the UK).

I use the chemical metal too, epic stuff!

You can get it from Maplins, titanium based stuff, steel based stuff etc

Glad to hear you got the problem fixed

[Tango]

Yeah....I've used that stuff too. You can also get metal putty from Maplins and the like which is another fine bodge emergency repair.......
