I was doing a annual pm of my 33 and was just curious to check the throttle linkage\cable. I pushed the throttle to full open and then check the throttle linkage\cable at the end of the link and found that I could turn the linkage another 1/8 inch or so. Therefore I could get more out of the unit if I wanted to adjust the linkage. Now.. I am not sure of the verbage here but let me try it another way. I decided not to adjust the cable\linkage as this is my way of controlling myself from running the unit up full throttle but... my question is... What should be the out of the factory RPM be at full throttle?

You should have a governor on your engine to control the wide open throttle RPM. My guess is it's somewhere around 3000 RPM. Adjusting the throttle cable or linkage should not have any effect on the RPM at which the governor kicks in.

Right, but if you could get it more throttle, wouldn't that help it in high load situations, where you aren't on the govenor?

I can't tell you what high idle is on your 33, but the op manual will. High idle is set at the throttle shaft on the injection pump and is seldom if ever off by much. If I were you, I would adjust the cable to achieve the high idle spec and use it whenever necessary.

A bit off topic, but didn't I hear that the the Class III have no governor ???
Don't remember who said it though /forums/images/graemlins/confused.gif

Wrong. Very very few offroad engines are without governors. In fact, I can't think of anything bigger than a weed eater or chainsaw without a speed governor of some type.

At some point, someone said that the class IIIs didn't have a governor (DieselPwr maybe?). That's not the case. As RickB said, there is a governor, and it's driven by weights similar to flyweights. The weights allow a cone to change position and move an actuator shaft that connects to the injector pump. That's the simple description. /forums/images/graemlins/crazy.gif
The governed speed for our engines is 2815 to 2855 RPM no matter if you have a TC35 or a TC45.
...now I sure hope I didn't "lie" too much. /forums/images/graemlins/laugh.gif This is all in the Repair Manual and I'm paraphrasing heavily. /forums/images/graemlins/blush.gif

I think the rpm range and the torque curve would have to be analyzed to say for sure. If the maximum torque is at 2500 RPM, wouldn't you want that RPM to be achieved under all load conditions? If your throttle is above that RPM, then the injector pump should control the flow rather than throttle position.
Sounds good, right? Well, it's just a SWAG from what I read about governor operation. /forums/images/graemlins/blush.gif You may well be correct in your assertion. I'll have to defer your question to a real expert. Any takers? /forums/images/graemlins/wink.gif
