Governor adjustment

[DannyT]

Could you raise the rpm that the governor pulls back at by replacing the spring in the throttle linkage with a stronger spring?

No, all that will achieve is the response will be quicker...

If you want to adjust the governor RPM (although it's not suggested) you need to adjust the arm that is attached directly to the governor (under the fuel tank on a honda/clone)

Are you sure about that? i have a tecumseh 5hp, and when the governor engages, it pulls against the spring to close the throttle. the spring is there so that the throttle linkage is flexible, and the governor can pull back on the throttle even when your foot is hard down. So my thinking was that with a stronger spring, more force would be needed by the governor to overcome the force of the spring and push back on the throttle, making it only kick in at a higher rpm.

The governor will kick in at the predetermined RPM no matter what, when & how it acts upon the throttle is another matter... which then becomes a dangerous situation that usually leads to catastrophic consequences...

If you want higher RPM, either adjust the governor correctly or remove it altogether...

I'm inclined to agree with what DannyT states on the operation of the governor.

Governor pulls governor arm to close carb butterfly harder at higher revs, throttle arm spring pulls governor arm to open carb butterfly... when those two forces even out, you're at the governed speed.

lol looks like people just done believe you

i agree that the governor will kick in at the set rpm, but with a stronger spring, the force the governor exerts on the governor arm to pull back on the throttle won't be enough to counter the force the spring is exerting on the throttle until a higher rpm than the set 3600.

Strange considering I've seen what happens when you manually override a governor...

 

[Greyscale]

Wouldn't taking the 40-60 mins to remove the governor be a more prudent solution to this issue?

 

[DannyT]

I'd rather not completely remove it, because I don't want to have to constantly think about not over revving it. Ideally, I could just adjust it to get 5000 or so out of it.

Fabro man means when u over ride it guess what theres a piece of plastic and metal that will be loose in your engine and possible could act like a pinball machine .

5000 rpm is DEFINITELY over-reving it if it still has that plastic gear inside, with a stock engine you will most likely redline at under 6000 rpm without govenor anyway

 

[OzFab]

Valve bounce with stock valve springs usually kicks in at around 5000rpm...

Here's what happens when you over rev a governor... not to mention what happened to the engine...
