Hi I have a Troy Bilt Horse III with a Tecumseh HMXL70-132502 engine and the Carburetor is broke and can't find one.

My question is how many ft lbs torque would power my tiller the same or more as the 7 horse power Tecumseh ?

I am thinking something like a 9 ft lbs gross Briggs & Stratton Over Head Valve ?
Or Do I want more?

serial # 848062

As long as it powers it as good as or better then the 7hp on it now that is fine.

All the engines I have been looking at list there power rating as Torque (ft-lbs, gross )

I am trying to gain a point of reference to understanding how much Torque is.

I think 9 ft-lbs would be about as powerful as a 7 hp
or 14 ft-lbs about as powerful as a 12 hp... That sound about right Âż

I just found there is a law suit over this torque thing

Here is a part of what I found

www.madisonrecord.com said:
"Beginning in 2007, many companies began labeling their lawn mower engines with torque, "despite the fact that engineers assert that 'torque' is not an appropriate quantifier of power and should not be used in power labeling"

Really that high? So 12 to 14 ft lbs would be what I want.

From what a gather from the law suit they made the move to torque to give the dealers room to lie. The lawsuit even says QUOTE "For example, Tecumseh reported one of its lawn mower engines produces 3.67 horsepower, yet it told the public the same engine produced 6.75 horsepower, Lemay alleges" End QUOTE

You know... I think Torque is a great way to mesure a engine for L&G work. The problem is that they have always been rated at HP, and thats what we have learned to judge power by...

Other than that, I have no real idea. I have not gotten the hang of the new Torque ratings yet.
Yes I am the same way... This reminds me when they made the move from Cubic Inches to Liters.
Friends in school were talking about a 5.0 and I had no clue what size engine that was..
Once I got it in my head that 5.0 L was around 305 cid and 5.6 L was around 350 cid I still use that as a reference to this day when ever I hear or see x.x Liter engine.
