Snapper mower with 6HP B&S runs very 'subdued'

Hi

We bought this mower in 1998 new and it has been very dependable. It starts right up on 1 pull - but the engine doesn't rev up the way it should.

There is a small lever near the front of the engine which 'slightly' changes the engines umph. It used to be covered with a small metal cover which fell off years ago so often when I push the mower into shrubs that lever gets pushed in and I have to pull it out.

The top of the engine says 'Diamond power'.

What do I need to do to make my mower rev up.

Thanks

At that lever at the front right corner of the mower is a spring that connects through a hole in a metal tab. Pull that tab out towards the front of the mower, bending it a little. This increases the engine rpm the farther you pull it out. Pushing the mower under shrubs often bends this back, so you may find yourself doing this once in a while.

Ok we are in the right area. I think that tab is out about as far as it is going to go. I just now took a hammer to it see if I affect the spring tension.

The engine revs up as it should when I pull that spring out further with my hand...

But that spring doesn't have much spring left in it. It's also pretty rusty. About 6 months ago I threw the mower in the jeep and drove to the mower repair shop and said I needed a new spring and he said "No you don't".

Should that spring be taut ?
Does that spring have a fancy name ?

Thanks

If your linkage looks like the picture, you bend the tab the spring is hooked into forward to increase the speed, don't tilt the tab bend it forward at the base. Have a good one. Geo

Now that was an excellent suggestion ! I wish my lawn mower looked as clean and new as the one in your picture. I bent it down at the base and it did pull the spring out a little (I think) but the rivet is starting to get a little wobbley.

[Edit: I re-read your post. My 'linkage' isn't quite like your's, it actually is a little more 'solid' but I was able to twist it forward 1/8" or so and that makes a big difference].

Thanks for your help!
