Question about Garden
After replacing the filter & plug, and adding fresh gas, my toro mower w/ a
6 hp Briggs engine just won't run well. At idle and at speed, load or no load, it constantly varies in rpm and starts v. hard. Never a problem until this year, so I'm stumped, especially since I see no idle adjusting screw on the carb.
Thanks in advance for any help or tips.
The reason it surges is it's not getting enough gas, the gas is stale or has water in it. Unscrew the jet out of the bottom of the carburetor and clean it and allow the gas in the carb bowl to drain out. Refill with newly purchased gas and be aware that gas for small engines should not be kept more then 30-45 days. I work on these units for a living and 70% of what we see are fuel related issues.
Also, the choke should never be on all the time. If you have a primer on your motor, it's doubtful you would have a choke. Perhaps you are looking at the throttle plate.

Try running the engine without the filter and check if the idle would smoothen, maybe a little high. If problem persist, then it would be fuel delivery problem. If the idle is constant (but high), then some sort of blockage on the air filter or a vacuum leak.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
