Lawnmower confusion

Posted by Michael Dobony on October 7, 2009, 3:42 pm

I have a 6.75hp Craftsman lawnmower with a Techumsa engine and my son has a
4.5hp Craftsman lawnmower with a Briggs and Stratton engine. I just cut my
son's very tall, thick lawn (3 weeks of rainy weather) with his 4.5hp mower
and it never bogged down to the point of stalling and rarely slowed down
much, even taking full width cuts. OTOH, my 6.75hp mower bogs down on thin,
long lawn (2 weeks little rain) to the point of totally dying if I take any
more than a 1/4 width cut. What gives?

Which is why people who are in the know avoid Tecumseh engines like
the plague.
That and the fact that after a couple of years they usually refuse to
run at all & even a good mechanic is hard pressed to change that.

That's complete and udder ( :) ) bull-hockey.

I've a nearly 40-yr old JD 112 w/ the 8-hp Tecumseh that still runs just
fine, thank you very much. It does have a new carb as after all those
years the throttle valve arm wore so that it had enough air leakage to
cause surging and make keeping mixture was difficult.

The 8-hp is plenty for the 38" 3-blade deck.

So, 40 years ago, the quality was good?
