Should i sell my brand new 389

@Ezrider_48501 has one on his 359 I think. His box is mounted on the driver's side behind the pump. The one I had was on the floor behind the driver's seat. You could here it click when it adjusted the throttle. You could set high idle with it as well and do away with the hand throttle.

 

My uncle welded a bolt under the peddle trying to slow down his. It got broke off about 10 miles up the road....it was family driving them. He would cut the pump back and they would just turn it back up too. Lol. He knew what they was doing. I was ridin with them one day on a short trip and he said pops cut the fuel back and i havent had time to fix it yet. It was still doing pretty good.

 

Beats me , it was governed by the injection pump
It would rev to 1850 and that’s it .

 

Same as you would any engine.....by metering the fuel delivery at max rpm

 

Ahh, so it wasn't governed as much as it just ran out of steam on the top end.

 

No it was governed at a set RPM. That’s what a govnor does is control RPM by metering fuel. Course there are several different types too. In the end their job is fuel control.

 

Whatever floats yer boat.

 

Why do you think a mechanical diesel will only run so fast with no load, full throttle?

 

Well splain it to me so I can understand it.......if you can.

I’m betting you don’t know what a govnor is. Google it

 

Lol, it's arguing semantics. No need to get pissy on the internet...lol.
The original argument or comment was it was governed at a certain speed. Which you can't do with mechanicals. Why? Because the way they are governed, like you said. So you cut the fuel back...OK. the truck has no idea how fast your going......because it is mechanical. It just runs out of steam. Now, you are going up hill with your foot in it, your not going to achieve your speed because you don't have the fuel. Same as fighting a stiff wind. Opposite of downhill. Now you can still have your foot in it because you don't need as much fuel. You are still gaining speed and still putting fuel to it becauss you don't need as much. Again, because it is mechanical and it doesn't know how fast it's going. So, going back to the original point, you can't govern a mech at a certain speed unlike a new truck, because the mechanical truck doesn't control speed as it does fuel delivery. The need for fuel changes upon conditions.....unlike the speedometer.
