78 CB125s carburetor leaking
« on: Mar 03, 2017, 22:01:46 »
Hi all, recently noticed my carb was soaked and lot of petrol on the exterior of the engine, dripping from the carb. I thought something must be up with the carb so decided to drain it and wipe the thing dry. Only to notice it all soaked and little drips again. Can't figure out what's up tank petcock is turned "off"

At the moment I need to just stop the leak. It's just below 25* f here so not planning to work in the garage anytime soon.

Any advice?

Carb off, float chamber off, clean, check the condition of the floats needle, check the float itself is in good order and free to pivot on the hinge pin, reassemble.

Replace fuel tap.

Fit inline fuel filter.
If it ain't broke, then I haven't been hitting it hard enough.

Thank you! Got the fuel like tied off for now too cold to work. Looks like petcock on stop still lets out quite a bit of fuel.
