Hello,

I have a Briggs and Stratton engine, 15.5 HP which has gas in the oil. The main thing that I found is the broken seal in the carburetor, the one that seals the needle when it's up. My issue is finding the spare seal, I have a picture of the serial number from Nikki.

Cannot upload picture, the serial is: 694670N G02702 0529 B

If you have this style seal, the little center o ring IS your issue. 
 
It must be seated on the white plastic part first. A little di-electric grease will help 
it slide into the aluminum carb body.
 

 

Hello. Thanks! I fitted one that I found, hope it works

Plz post back how it goes..
