Hello every body, Done a lawnmover with great results, whent from 5min 60ml to 7min 60ml and exsaust manifold temp droped 18degress celcius,

the mover runs better and colder. here is a pic.
used the small bit. i grooved from 3 to 9 on this one.

Hey Markus,

Awesome results! Anyone else do their lawnmowers? If you have, give us your report on the forum. The off-road engines are easy, big result money makers. We haven't even started to make a dent in this market. The Groove gives a huge reduction in emissions to these engines, too.

Hey Markus, Good morning. I have grooved a 16.5 briggs and stratton riding mower.

It consistently burns half the gas it did before the groove.

The temperatures of exhaust masnifold dropped almostr 100 degrees!!!!

A little groove makes a big difference.

By the way I also used the small bit to do this.

The groove process took 45 minutes to complete.

The first year after the groove saved us $175.00 in gas to mow our yard.

That is when gas was only $2.90 per gallon, now this savings would almost be double.

LITTLE ENGINES LOVE THE GROOVE!!!!!!!!!!!!!!!!

Keep up the good work Markus!!!
