Remove air filter and spray it into throttle

Hi there. It sounds like its getting to much fuel and flooding the carb.

Is battery powered, did you try calling sears tech center for further info ?
i have found them to be very helpfull with mower problems.

sae 30.

Check the governer, its a lever that pulls the throttle plate from the engine side. Try manually overriding it (twist it open as the engine's running) and see if that does it.

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.

sounds like the carburetor is a little gummy and when the engine shuts off it goes to full throttle by the govenor for easy starting but is supposed to return to the set 3600 rpm. try spraying carb clean on the carb and wiggle the govenor arm to make sure it move freely

if cable is all intact, just hook it back up, if broken, then replace it.
