All of your pictures show the engine outside of the mower. Do I have to take my engine out in order to make repairs? That seems like a big hassle. :\

Briggs and Stratton 675 Series Repair: white and blue smoke

Mon, 24 May 2021 23:34:31 -0700

ok so my mower isnt what i had to pick from on choices, it's just a simple little 21" MTD push mower. i recently changed the oil and changed the blade on it. never once had an issue with the mower like im having now. ive got oil basically pouring out of the airfilter, i've got to prime it every single time, for instance, i turn the mower off ( release the gas bar) to light a cig, and ive gotta prime it 4-5 times to get it to start again. mower wasnt even turned off for more than 30s. not to mention when i turn the mower off, its still running while pushing out a lot of whitish blue smoke. sometimes its more white, somethings its blue. this issue has never happened prior to changing the oil. not for certain what to do or to even make of this. *side note* prior to changing the oil today, the oil had not been changed on the mower for nearly 3 yrs. i'm not the original owner

Briggs and Stratton 675 Series Repair: Can someone post a picture of the throttle mechanism/springs?

Sat, 24 May 2025 13:55:44 -0700

I just recently took my B&S 675 apart to clean and check some things and in the midst of putting the engine back together one of the two "springs" for the throttle cable that connects to the carburetor came off. I can not for the life of me figure out how to put the bastard back on correctly, can anyone post a picture of the throttle cable springs connecting to the carburetor on this engine? This engine is on my Briggs & Stratton Earthquake auger with the 675 series engine.

Thank you!

Briggs and Stratton 675 Series Repair: Why is my Briggs & Stratton 675 series mower engine running too fast

Sat, 19 Sep 2020 18:17:04 -0700

Part way through my last mowing session, the engine suddenly started running at high revs, the accelerator lever does not alter the engine speed even though it works correctly. Is there an adjustment screw on the carburettor? Or is it a more serious issue.

Briggs and Stratton 675 Series Repair: Run problem on old Briggs and Stratton Troy Bilt tiller engine.

Fri, 13 Apr 2018 06:41:37 -0700

Engine will start if choke is closed, but dies when choke is opened. It will continue to run with choke almost closed for a short time, then it dies. I've verified that there is not a problem with the fuel line or filter. When the line is disconnected from the carburetor, fuel flows freely. This tiller is an early version build date in the early to mid seventies.

Briggs and Stratton 675 Series Repair: My Toro self propelled lawn mower starts right up and then dies.

Tue, 10 Mar 2026 16:47:06 -0700

My engine starts up and runs for a few seconds and then dies. I've clean my carburetor and took the float bowl off and cleaned it out. The bowl had a small pieces of a gel substance in it. I removed the carb and the float bowl and blew them all out. Also took the float of and needle valve and blew out the carb. I've checked the fuel lines and no cracks. Put it back together and it does the same thing. Any suggestions??

Briggs and Stratton 675 Series Repair: How to stop oil flow from crankcase breather house to air filter port

Wed, 04 Dec 2024 21:37:10 -0700

675 Series. Engine build date 6/10. Runs a Huskee log splitter. Oil comes out onto the air filter from the crankcase breather hose when engine is running. Oil reservoir has NOT been over-filled. What's the fix? Also, when i enter the model # into the B/S website to obtain a manual, it says 'no matches found'. I have a serial # as well. Any clues on how to get a manual online? Thanks.
