Default Ezgo governor adjustment 4 strokes

The governor is the device that limits the speed of the engine. The Ezgo carts are set to run around 12 - 15 mph from the factory, this is to reduce liability for golf course's. It is also a federal mandate (USA)that these vehicles go no faster than 19.9 mph. Any faster and the cart makers would be required have to have seat belts and other saftey features which are not practical.
Ok, with that said the gas carts can run faster by adjusting the governor, but keep in mind that running the engine faster will increase engine wear.

The governor is located on top of the rear axle housing, on some models there will be a protection plate above it.
There are a few different types depending on the year of the cart. This is for the 4 stroke carts (it's the same for some of the last 2 stroke models but i'm not sure of the years). The first one starting around 1991 to 2000 will look like this.


The threaded rod that runs through the spring has a bigger nut and a locking nut which is wire tied on factory carts to hold it in place. These will need to be tightend up till the desired speed is reached.

These engines have a rev limiter which will cut the ignition off and on around 4300 rpm. The engine will sputter at higher speeds. You need to set the governor so the engines speed is under the rev limiter. It will take some adjusting to get this just right.

The 2001 and up is adjusted the same way(brand new models may not be the same), it looks a little different and has only one self-locking nut.

Alright, one more ? , I tightened the gov. up, it runs like a bat out of hell, now the problem, off idle it wants to burp a little, like it gona spit back thru the carb, but once you get past that it`s runs great, do I need to adjust the valves ? or is it too lean ? Thanks , milo

You just need to make sure the carb closes before the ignition is shut off. It won't hurt to adjust the valves. I would also recomnend you run a good synthetic oil like Mobil 1.

This burping happens when you first step on the gas, once you get to quarter throttle all is good , Thanks, Milo

so, the govenor is what slows the engine down when the speed gets to be a certain level, right? jon, you showed what to adjust, now, how far do we adjust it? I'd like to get a little more top end when going through some soft stuff. as it is (i think adjusted it, maybe not), it starts out okay, but when it starts to get up to speed going through a field, the balls fall out and gets bogged down a little. also, would like it to have a little higher rpm when at cruising speed.

it's there. i just got to get it to come out!

i guess i could wrap my little brain from my big melon head around this a little easier if I knew what was the mechanism happening here. so, throttle cable pulls, tighter the spring, then what? am i watching the cable that goes in back, or the mechanism at the other end of the lever?
