Briggs & stratton will not start or stay running.

[Tyler23513]

I have been working on my 6.5HP push mower motor. I looked on B&S.com and they didn't have my manual my model number is 126T02-0675-82. The issues that I am having are I can spray starter fluid to fire it up but it shuts down right afterwards. I was able today to get it running but I had to hold the lever that attaches to the flapper in the carb than goes to a lever on the EXH end of the ENG in the closed position on the carb. I was told today that it was the choke. I have noticed that when the ENG runs a while the flapper tends to stay open. can anyone give me some guidance or some hints on where to get a manual to help me out. thanks in advance.

Could your model number be 126T02-0675-B2? If so try these two sites. One would be for parts and the other is a service manual. My guess that your are going to have to clean and rebuild the carb.

ok thanks for the info and the links. so where can I buy a carb rebuild kit?

 

[Rivets]

Please double check your model numbers and post back. You can get the rebuild kit at any good repair shop. The numbers you posted I cannot find. When I get different numbers, I will get you a part number.

Rivets, the model number the guy posted is correct. the carb repair kit part number is a 498260.

I won't disagree with ILengine. For some reason I can't get the number to come up in Briggs or anywhere else. Must be my old age, thanks for your help IL.

What you have is the Briggs Ready Start.
Sounds like it could just be the carb causing your problem but check out the link above.
If the lever is not set right or sticking it can cause bad start but going by the picture your choke is working.
The metal lever at the exhaust were bad for sticking but they seem to be sorted now.

i posted this video today that i recorded eariler could not figure out how to post it on here so just put it on youtube. Im planning on taking the carb off and rebuild it if tthis confirms that's the issue.

My Briggs brute mower engine had the same problem, and after a good cleaning, and a new needle seat it runs fine. The seats in these carbs go bad quick from sitting when not in use for long periods of time like over the winter.
