Question about Garden
Mower engine suddenly races uncontrolably Removed inlet manifold in order to replace fuel pipe and connect to carb. Engine now runs but suddenly surges madly. Unable to contol by throttle and only option is to shut down. Help please !!
Sounds like your governor linkage and or governor control fan arm " most small engines have them to control over speed" is binding or maybe has dirt and grass built up.. Or the return spring is disconnected. Once it starts to race manually move the governor linkage back an let go see it it stops racing.. Then release if it races again..check the spring if connected...you must check the governor fan it is located under the top housing..it uses the engine fan calling air to slow the engine when over speed occurs by pushing the governor linkage back to slower speed.. Check it out...good luck..
