Engine Races

[te100]

my riding lawnmower (Murray 16hp ohv)engine(B&S 313707 0126-E1) runs at full speed(very fast real high rpm) no matter the throttle position. I have to choke to slow it down. I cleaned the carb(walbro lmt) cause it was flooding engine(flooded oil). I can see the butterfly closing when I throttle down but the engine still runs at the same speed very high rpm. Any suggestions?

(and I thought this was about races like on a track) Check your governor and linkages

One of these two manuals should help you find the correct diagram of your governor linkages.

Sounds like the governor gear in the crankcase is not pushing on the governor rod that goes through the crank case. Really the only way I can think to check it is to remove the engine and open the crankcase.

I adjusted governor via this links instructions and it seems to be running alot better now I can actually throttle down now. Thanks to all :thumbsup:
