[Shop-talk] mower engine issue

[Donald H Locker]

It's that complex because it's application is supposed to be a constant-speed application; as are also generators, welders, pumps, and most applications for small engines, for that matter.  Engines are rated for power and life at a specific speed; faster than that and life goes down, slower and power is down.  The governor tries to get you the best from both worlds.  For variable speed applications (driving vehicles with mechanical (as opposed to hydrostatic or electro-motive) transmissions), disconnecting the governor can be a useful upgrade.

alright, I got it running by taking it more-or-less apart and guessing as to which hole the governor's spring went into. that thing is a death trap. my son and I love it. 

but it's still doing the rpm oscillation. so basically, I fangle a way to connect the throttle cable to the butterfly in the carb throat (where the governor is currently connected)? and then I can remove the associated governor parts? I ask like that because whatever's driving the governor is deep in the case. I don't know that I'd take it apart to get the stuff out of there, so I can just remove the lever that attaches to the throttle butterfly and call it a day? or should I assume something in the case is messed up and it needs to come out? 

and why should a friggin' chinese lawnmower engine be even this complex? 

but anyhow, it runs. and it's got a little power. someone's going to end up in the e.r., I'm sure. <grin>

It'll be crisper with a direct connection and should run just fine. 
Depending on the carb size, it may bog slightly if you floor it too 
fast; the governor damps that action a bit. 

Worst that can happen is you blow the motor, or run the cable 
incorrectly and the throttle sticks and you plow into a wall.
