Right, this is totally doing my nut in!
I've got this Honda CB125TD-E, I've stripped and cleaned the carbs, done a few other jobs etc, and after re-assembling everything bar the side covers, turned the fuel tap back to 'on' ready to start her only to see fuel pouring out of the bottom of both carbs!!! Slight panic, turned the tap back to 'off' and it eventually stopped. Fine, checked stuff like the drain screw was fully done up, check, even let out more fuel by undoing it. Dismantled carbs to check float chamber, blew air through fuel line and lifted float, air stopped (got puffy cheeks etc :o ), re-assembled carbs and remounted, fuel on, more pouring of fuel. Off comes the carbs and again dismantled.
Now, I can find NOTHING wrong with them. I have only cleaned them and dismantled the float assembly (the guy I got the bike from said one was sticking), I haven't touched either the main jet body or the pilot jet. The floats themselves aren't punctured or full of fuel and nothing seems to stick on the assembly. After that there's not much to adjust and I've done a static setup as per the Haynes manual. There's only one bit to attach the fuel pipe too so it's nothing THAT stupid and I've stripped and rebuilt lots of old SU carbs on Mini's over the last 10 years so I'm familar with the mechanics of how they work.
As far as I see it I must be missing something REALLY obvious, I can find nothing of any help in the Haynes manual and have followed it to the letter (ish) with regards to rebuilding it (they're even more basic than SU carbs!). Has anyone got any ideas or suggestions cos I'm at a loss :(
