Having Trouble Figuring Out Hunting On Briggs 450
#1

Hi everybody happy to join your forum! I've recently been given a sprinter mower with a 450 briggs 148cc in excellent condition... I have dismantled the carby cleaned it put new gasket and diaphragm on and new governor and idle spring.. fresh fuel oil is good still... when I crank it over it starts beautifully but is hunting and not sure what to do now as I thought the gasket would solve it !! Plz help

Bend the idle spring tab to stretch the spring a bit more, should stabilise the governor. Bend the main spring tab out as well if highest rpm seems a bit low. This is all assuming you cleaned carb properly etc, intake manifold not cracked etc. Also assuming this is the 450S not the later 450E..
