Question about Garden
My mower surges. its a Murray, model number 220012X92A, 4.0 HP, Sprint, 22'' Throttle Free Design. i changed the spark plug, changed the oil, replaced the gas and it still surges. it starts up fine but then it revs high then low, then high and this continues through the whole mowing process. what do i need to check? also is there a manual with directions that i can use to follow?
First check to see if you have good clean gas in it. No water. if you have good clean gas. then I would recomend taking the gas tank off wich should have a plastic carburetor mounted to it. after that is removed and free of excess dirt. take the carb off there should be 5 phillips head screws. pull the carb off gently while observing just how it all goes back together. you may want to take pictures. you will find a fuel screen that you should take off and clean with carb spray. also there is a fuel pickup tube clean that also with carb spray. a couple words of caution if using compressed air Do not carried away with it. also same with the carb cleaner to much of it in rubber primers is not good.
