2018 Platinum 30 SHO Governor Adjustment

Hello-

I was reading a thread about adjusting the engine governor on the 414 cc Platinum 30 SHO motor.....

Do those that have bumped it up really notice a difference?

I want to increase the power...but I can't find the governor. Can you guys help me?

I really appreciate it

modifying the governor setting will void your warranty.

Only if you take it out of spec. Making sure it's set to the upper end of the spec-ed RPM range should be perfectly ok.

I doubt most people would have a tach to accomplish the correct settings.

That may be true. But if you're going to adjust that setting on a new $1,800 machine, you'd be well-advised to spend the $15 on a tachometer. Get one that's also an hour meter, and it will help you with maintenance timing. This one has a replaceable battery, which will save you from buying a complete replacement unit when the battery eventually dies.

Keep in mind that the engine is already going to be tuned for the best performance. You are just throwing off those variables by raising the RPM even more, and risking damage. If you are just doing this to be able to throw the snow from an already impressive 30-40 ft to 50 ft, it's probably not worth it.

If you can't find the governor then I suggest leave it alone.

That's not always the case. IIRC, for the LCT engined Ariens blowers, Ariens specs RPM at 3600 +/- some amount. LCT specs max RPM for the engine at 3800 +/- some amount. So Ariens is running the engine below max speed (and possibly just a hair below peak hp as a result, but there's no HP curve published for that engine so no way to really know).

The other possibility is the engine speed being set wrong accidentally, by the factory or dealer. Checking it, at least, is certainly not a bad idea.

Since it is a new machine under a warranty if you feel that it is not correct , take it to the dealer to have them perform a rpm check and or adjustment if needed.
But as stated if you are just wanting to mod a new machine the risk could all be on you as voiding a warranty.
