Why would you want to? It is computer controlled, so I don't see how you could.

Well, there are a couple of things I can think of. First, your low RPMs might be caused by a bad fuel/air mixture, which is often the O2 sensor which is around 50 - 100 dollars. Another thing it might be is is bad spark plugs or wires. For what you're talking about, you probably don't want to adjust the RPM level (I take it you mean its idling RPMs) however you can do so. Since your car isn't carbureted, you would have to edit your ECU, which can be done with specialized computer programs installed on a laptop which is then wired into the ECU. Those run anywhere from 200 dollars on up.

Practically speaking, no you can't adjust the idle speed. More to the point, the problem is not simply a matter of misadjustment, and if you were to somehow effect an adjustment, that could very likely cause other problems. Something is broken/malfunctioning/disconnected/etc. The thing to do is find the problem causing the poor idle. When the problem is fixed, the idle speed will fall into line.

How do i adjust the governor on a 5hp Tecumseh engine?

After the carb has been adjusted to proper specs and is running ok you can adjust the governor by bending the wires to either up the rpm or to lower it. Also a better way without ruining the wires is to adjust the small screw that holds the governor piece in place. You can loosen that screw and push or pull on the governor to adjust the rpm. Usually pushing the governor will increase the rpm. You can always readjust, so you don't have to ruin the metal pieces connecting the carb and the governor
