How to Adjust Lawn Mower Engine Speed - Easy DIY !!

[@chriswindham9868]

Find a blade tip calculator. Input the blade length and calculate for 19000 fpm Close to 3300 RPM for 22” I believe and 3400 RPM for a 21” blade.

I set them 150 below max just to be safe

Thanks! I have the 6.75, and the self-propelled feature feels like I'm running! I assume adjusting the rpm's will fix this. (Hopefully)

Usually you can adjust where the cable is clamped for self propelled, on the handlebar a bit towards the motor

[@skygirl81103]

​@CrOnDYv lowering the rpm's did the trick, did everything exactly as you did (except measuring the the rpm's) just went by sound and feel. This was a great video! Thanks!!

That was an excellent presentation. Greetings from Ireland.👍

[@Buckwsr]

Thank you so much!

[@donspreiter4135]

Good information. What stroke setting did you use on the tac

[@Buckwsr]

I think I used the setting that the tool defaulted to right out of the box. The tool includes instructions on how to set it up for various types of engines, but I thought discussing all that would be excessive for the kind of video I was making.

Thank you Buck!! VERY informative!!

[@modman3295]

does this require the engine to be running?

[@657449]

Where do you find the correct RPM?

[@Buckwsr]

I'm sure the info is out there somewhere on the internet, but I was pretty much going by the sound of the engine, and it's performance. I never looked up the specific factory recommendation.

[@philliphall5198]

Look up engine specs It will tell you 😊

[@JohnAnglin-tg5mg]

But if you bend that tab too many times won't it get weak, loose, or God forbid even break off?

[@Buckwsr]

I've never had a problem with that. never. And you really don't bend it very much. A little goes a long way.

Excellent video thanks so much!

[@randylearmonth4047]

Thank you , very informative

[@RolandChavarria-t6s]

Ty, but machine should run between 2950-3100 rpm, I saw on Steve's Small Engine Saloon, 😅😅

[@philliphall5198]

Really you need a tack to know what to set it at, please don’t overdo it or engine will blow 😮
