I have a c172 o-360 a4m. When I am done flying I have fuel on the nose wheel pant and on the front of the air box. Just had carb rebuilt, did not fix it. Any suggestions ? Thx

Wait, you are flying an airplane that is leaking so much fuel that you have it dripping out of the cowl, and, you flew it after the first time you noticed?When I am done flying I have fuel on the nose wheel pant and on the front of the air box.

Ya gotta love FAA licensed A&P's.....

Did it leak before you had the carb work done? If not take it back to whomever did the work.

Now you know why fewer and fewer A&Ps will rebuild a carb or a mag. anything goes wrong it their fault.A leaking primer will also do it. But it would have to be leaking very badly, since it has to get past two check valves and the internal needle valve before it can drip out the primer nozzles and run down the manifold and out the carb.
Might be a sinking float, a misadjusted float, or a bad float needle valve.
Or even a loose fuel hose connection. Bad...
Check carb for a "sunk float". They might have missed it. Its a hole in the float.
Easy thing to check but some mechanics dont want to open the carb...
If it was a stuck float, it would be leaking all the time and fuel would be running out of the carb all the time.Noticed fuel on nose wheel pant first time, thought maybe spilled from checking sump. Cleaned it off, even more after flying it around the pattern, staying within gliding distance, a few times. Diagnosed as possible stuck float. Rebuilt carb, including replacing brass float with composit one. Three flights with no noticeable fuel leak. Flight four showed fuel on wheel pant and air box again. Been flying this plane for five years, first time for this .

Exactly.
Nor has any pilot over primed an airplane with the accelerator pump to the point it leaks on the nose wheel pant.

Buy a Mooney with an o-360, it's supposed to leak. If a Mooney is not leaking fuel the tank is empty.
Ben, we all know that you are a pretty smart engine guy but let me ask you this, have you never made a mistake? Have you never had a part fail?
Also, it might be that the rebuild was done at a 145 or at the manufacturer. If that is the case, it was most likely not done by an A&P but by a repairman. The OP did not say that it was done by his A&P. It might have been but you should not jump to a conclusion followed by ad hominem attacks against A&Ps in general.
One unfortunate aspect of a situation such as this and social media is that problems and mistakes always get brought up. The 99.99% of the time that a mechanic does his job well and everything works as advertised very seldom gets mentioned. Yet, somebody wants to be a butthead and make a comment like you did.
Ben, I enjoy the vast majority of your posts and the friendly banter you engage in with the rest of us. However when I read what I can only describe as your anti A&P vitriol, it really disappoints me.

If fuel from priming is still on the wheel pants after going for a ride, then it's probably not from priming.I do not usually prime for start up. in past winters I have left the oil pan heater on continuously, therefore no priming needed. So far this winter I have not been leaving heater on, so priming is new to me.
Good thing it doesn't say "must"I find it interesting that Garmin says there "should" be a minimum of 6 feet between com antennae, ever looked at the top of new SEP Cessna? There isn't 6 feet spacing. My old plane has ~ 3.5 foot.
I will try and tone it down a bit, altho.... Over the 35 years I have been flying.. I have witnessed some dumb assed., pizz poor workmanship by aircraft mechanics....
Rant off...
You should visit the NTSB database and compare pilot error fatal accidents to mechanic error... tell me which is the bigger group of dumb's.... I'm sure, I'm way more afraid of a pilot killing me than they should be of the contrary.
