leaky bing

I just put my moped back together after un-seizing it, rebuilding the carb, new petcock and changing the trans fluid. Went to fill it up and start trying to get it started..

Fuel began pouring, and I mean pouring out of (pic related) this little priming nipple thing.. help?

I just wanna rip, was so excited to get this thing going today finally

Please and thank you

Re: leaky bing

Are you 100% sure you put the float needle back in properly? Did you set your float height?

Re: leaky bing

I am a noob here but when I rebuilt the carb I just cleaned it well, got a new top, bowl, banjo gaskets, and a new float.

I replaced the float all together but it didn't seem like there was any way to set the float height, I just took the old one off and put the new one on and put the float needle back in the little notch

Re: leaky bing

You need to polish the needle seat. I use my drill and chuck up a q-tip with rubbing compound on it and polish away. (edited)

Yeah...

Re: leaky bing

Thank you for the handy infograph, friend. Very useful.

Will report back after some adjustments are made. The chinesium float I got from treatland seemed a little rough, should have known it would need some fitting

Re: leaky bing

Flip the carb over and blow into the gas intake port to see if it's sealing.

Re: leaky bing

Upon reading that infograph, I may have ruined my needle, if the part about not getting solvent on the rubber tip and it swelling up.. the carb was so gunked up and full of sludge and varnish I just threw the whole thing in a carb cleaner bucket for a couple days once I had it apart

You're suppose to remove any & all rubber before you toss it in the solvent .

Best to dismantle the carb completely . (edited)

Re: leaky bing

I know that much, I disassembled it completely. The needle was gunked up with so much sludge and varnish-gas I just assumed that the float needle was all brass though. I didn't realize it was a different material until after the fact

OK , that must have been very crusty . I've had carbs similarly bad

Time for a fresh needle and polish the seat mirror bright .
