Hi SAB
Same reason manual chokes on cars went out - because the average person does not want to be stuffing around with a lever (granted car wise, the choke was also an emissions issue).
Most mower 'users' (because apparently you don't truely 'own' an 'appliance' - you use it) just slam the lever to the bottom, kick it in the guts and leave it there until they want to stop.
Without a governor, they would open it right up, hit 5000 rpm, and send the con rod out the block and straight through their leg. Add to that the limits on 'blade tip speed' (especially in the US) and you have potential lawsuits on your hands through high revving engines. Besides, they need a governor for some applications like generators, water pumps, and possibly others
Personally, full throttle start, straight back to idle for 1-2 minutes whilst I check everything is off the lawn, etc, then use half throttle - if its thick I bump it up. Just wears it out quicker, uses more petrol and more noise to rev it flat out
Other issues are that slow idle cooks the briggs - I left one idle at approx 1200 rpm for 10-15 minutes once and the petrol in the tank was a solid 'bath water' temperature
Also (this is more tongue in cheek) I couldn't use the words smooth and briggs in the same sentence after using a Honda haha

Tyler
