Just bought this machine which hasn't been used for approximately 7 years. I have changed the oil, checked the filter and plug and it runs well for a few minutes then dies. If I give four or five squeezes on the fuel button it will start again easily but only run for a few minutes again. Suspect fuel supply or dirt in carb but have no details of how to strip and check. I have checked B&S web site and entered the model number but can't find any useful details. Any help much appreciated.

Click on the repairs index button then the Briggs carbs.
There are a couple that might be yours as there were a few carbs fitted to the 1200000 series engines .
So worst come to worst you might end up looking at a few different set of instructions.
If you have the primer with the hole in the middle you will need to replace the gasket between the carb & the air filter and when it goes together make sure the nuts are tightened evenly or it will leak air & not prime.

Maybe your fuel line is flapping on the inside of it.......... A good carb clean could be in order... Setting that long the seat could be swollen from Ethonal gas also ........

If it sets for a couple minutes when it dies, the bowl has time to fill back up to run again for a few more minutes...

Hope this helps Mon Ami ~!~!
