Question about Garden
Craftsman Trimmer/Edger 4.0 HP Engine races... Throttle moves ok. But its either slowest setting... any movement toward fast and the engine revs really fast... out of control. What could be the problem?
Most likely, the mechanical governor is damaged inside the engine. If you have tools, a sense of adventure, and lots patience, this can be replaced for a modest cost in parts.
If not, take it to a reputable repair shop.
The governor replacement involves engine removal, opening the crankcase, lots of parts-cleaning, and attentive reassembly.
Would be happy to help you if you decide to tackle this repair.
Hope this helps.
