I can crank my murray gas lawn mower 6.5 quantum

I can crank my murray (briggs Stratton) gas lawn mower 6.5 quantum throttle free, but it won't stay running. I can only keep it running by continual priming. What's wrong? Thanks,

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please rate me, Thanks
Good Luck, I hope this helped

Hello, I am using the Craftsman 675 Brigs & Station 190 cc lawnmower, and I'm trying to turn up the throttle. It apparently does not have a throttle adjuster, and I was wondering if there is any way...


After researching the engine application, I see that this 675 is NOT an OHV engine. It appears it is the L (flathead) engine with the standard features. The 775-875 Platinum series mowers have OHV engine applications. That being said, many mowers have the carburetors with the governed throttles set to run at the the OEM mandated maximum speed. Some (like the Briggs Quantum series engines) have the throttle plate still attatched. You would need to bend it back up and install an aftermarket throttle cable assembley (like Murray makes). You would connect the carburetor end of the throttle cable to the hole in the plate assembly that has the governor spring attatched. Some even remove the governor entirely (internal governor has to stay in) and connect a throttle cable on the plate controlling the butterfly in the carb. Your unit may have this feature with the plate having a few different holes in it in which you could install the end of an add on throttle cable.

Murray riding mower 12.5 hp briggs & stratton spitting oil & gas out of carb & muffler when trying to start


Drain oil... it is full of gasoline due to a bad float pin and rubber gromet in your carb. When your float pin and gromet fail, gas just keeps flowing into your carburetor, eventually flooding your motor with gas and oil mix.
