rpm governer settings tecumseh 10 hp

Hi I was wondering how or where I could look up the correct engine speed for the governer on a Tecumseh 10 hp snow blower engine. It is an older Lawnboy ST1032 model (1980's). I bought it second hand a number of years ago and it has always had a tendency to rev higher than other snowblower engines that I see. It really screams like a devil when opened out (but it is still in one piece after over 15 years with me). Thanks Brian |

Ben, That's why recently I've been concerning myself less with the horse power, rather with engine torque. The engine is never run to achieve the rated HP anyway, and that's a fact. At least when it comes to Briggs or Tecumseh engines, the HP/torque curve charts prove that.
Good way to summarize it all. In OPE it is more about torque.

  Richie, Go to :"Small Engine Warehouse" site You can get an 11 to 13 Briggs OHV for between $350.00 and $450.00. Much better selection on Snow Engines this fall though. With a 13 Hp OHV, even with EPA controls, it ought to produce at least 10 old fashioned HP! Sure would make you blower a hot rod!! Fred

Hi Fred, Believe me, if this engine suffers a catastrophic failure in the future, you can bet I'm going to repower this snowblower with a great engine to compliment all the other great features it has. At least the best that I'd be able to fit on it without requiring a modification to the sheet metal or polypropylene shrouds. It would really be something that would not be rated more than what the Tecumseh 11 HP OHV engine can produce, since that is the largest engine you can get on this thing. I assume that the friction disc and other components are rated to handle up to a certain amount of power, but I'd hate going beyond that, which would be very easy to do.

Ben ben ben, it's not all about torque, regardless how you word it or how many times you type it. First of all, it can't be. Without HP in these engines, you get no torque. Second, every OPE small engine that I know of has a higher amount of torque on larger HP engines. Third, saying it is all about torque, means exactly that......screw HP, torque is all we need. Not true. Forth, I am fully aware of what an engine does when it drops RPM's under heavy load, snow is not the only thing that causes that to happen on small engines. Fifth, I said torque was very important, it's just not all of the equation by any stretch of the imagination. And, here's an exaggerated example to show what I mean.......Let's say you had a 25 HP V-twin OHV engine on your blower with a relatively low amount of torque, the chances of it bogging down while blowing your driveway are slim to none. On the reverse side of this.......if you have a 4 HP engine with a relatively high amount of torque you're going to be into that torque all the time and very well may stall out because you don't have enough HP. You need a higher HP engine! Yes, I agree torque is very important but it's just not all about torque, it both! |

actually the opposite is true
Horse power is the result of torque.
Torque is a force Horsepower is a measurtment of torque doing work over an amount of time. The opposite is true of your quote. Without torque you cannot develope horsepower. Simple example lets take internal combustion engines out of this. Lets use an electric motor, why because an electric motor can produce force without a running start. Lets say you got a 100 pound object you also have an electric motor that produces and can be measured at 75 pounds of force. It cannot lift the weight. It has force but cannot produce any horsepower cause it cannot move it. "It is torque that moves your car but it is horsepower that sells it." "It is TORQUE that makes the world go round." Ben
