Sanborn 160cc field trimmer leaks gas

Hi,

I have a Sanborn 160cc field trimmer 22"
SB-WFT-16022-E

It looks like it is made by MAT engine Technologies LLC

I can not figure out what make engine this is on it.

I got it new this year, it leaked gas after I first used it. I called the customer service number and they sent me a "new" carb.
I installed it like they told me. It leaks gas still from the "new" carb. I have only been able to use this thing 2 times now.

Any ideas how I can fix this?

Thank you in advance for any help.

 

update:

MAT engine Technologies sent me another new carb. But still the same problem fill up the gas tank and gas leaks out of the carb near the air filter. I think that the inlet needle seat & float is the problem? The numbers on the engine do not look like it is a B&S or Tecumseh engine. I would like to just fix one of these carb's.

Any ideas?

 

I'm speculating here, but it looks like a Chinese engine, maybe a Honda clone, someone more knowledgeable can deny or confirm.
MAT website leaves a lot to be desired providing info.

best pic I could find.

Did it come with an owner's manual?

 

Yes that is what is looks like. Different color, but that is it.

It came with a manual, but like the website it does not help much. I would like to fix one of these leaking carbs.
I guess I'll need to go back to calling customer service again and have them send me another new carb. again.
Thank you for the info.

 

Is this a Chinese engine?

I took the carb a part and the needle has a small groove on the end? The name on the carb is WISDOM P18A. Not finding anything on getting new needle for it if that is what it needs? I'm guessing that the problem is the needle is leaking gas?

 

I found that the float needle valve of the 3rd new carb. has a groove on the rubber tip of the needle.

Any Ideas where I could look to get a new needle valve for this?

 

On 4th replacement carb. from Sanborn customer service.
They would not supply a gas/fuel shut off. I went out and got one so I can atleast use this thing, and the tank of gas can not leak out on the ground right after it is shut off.

Even shutting the gas off and it runs till it is out of gas, it still leaks gas from the carb/air filter area. Just not the whole tank of gas anymore.

Last time I buy anything made by Sanborn/MAT.
My mistake by not making sure it had a B&S engine.

Thanks for the help

 

MAT Holdings - MAT Holdings: Products

According to their information page

"China is home to 20 multi-operational factories and five administrative offices offering services that include product development, quality control, product sourcing, assets control, accounting and shipping logistics. In 2006 MAT Holdings, Inc. shipped over 14,000 containers from its China facilities."

Based on that statement from their web site, I could take an educated guess where your engine came from - and those junk carburetors. I see two possible solutions - live with the gas leak or find a suitable B&S engine to mount to your chassis.

The fact that the company does not even want your old carburetors back tells me that they know about the problem and do not care.
