I used a gasoline powered weed whacker today fir my first time. At one point the engine started revving like crazy by itself and letting go of the throttle didn’t slow it down so I flipped the kill switch. Now I can’t start the weed whacker anymore. Being new to weed whackers, I dont know what to do. A mistake I may have made is I didnt switch off the choke switch after the engine had started. I tried switching it off once and the engine stopped, so I just left if on this time. What might the issue be here and how would I diagnose and fix it?

Hello Dominic, I would let your engine sit for a few hours, clean off any debris and try to start it again, the choke needs to come off when it is finished starting, or you could cause damage to your engine. It should start after letting it rest. Can I ask would it try to turn over and didn’t start or did it not try to start at all?

Yes, it likely flooded. After the engine is warm, if the choke is still on it will run fast. But usually, it will choke itself to death. It could also be that, since it sat a while since last used, the throttle linkage is gummed up.

It turns out that the part with the string for starting the weed whacker was worn out so needed to replace that, now it works fine. My friend who owns the weed whacker was able to tell when he pulled the string that that was the problem.
