RE: real world fuel usage 120

If the*information below*doesn't appeal to you, get a mechanic. You can hurt yourself and the engine if you get governor adjustments wrong.

There should be no reason to remove the governor to set the throttle stops. That is like having to remove an engine to change injectors. Unless you know for an absolute certainty which adjustment does what, don't touch any of them.

Get someone to move the throttle up top*for you. When the wheelhouse*throttle lever is at full ahead, is the governor throttle*lever against the stop screw?

You can disconnect the throttle lever at the governor and see if you can obtain high idle rpm by moving the lever by hand to the stop.

If*doing that*gives you high idle rpm, reassemble the control *then loosen the screw that locks the throttle wire (to the*throttle lever on the governor)*and move the throttle lever to the stop with the wheelhouse throttle*at full ahead and tighten the screw again. Make sure the lever goes back to the idle stop at idle throttle setting.

You can safely make a*SMALL adjustment to*the stop screw*on the speed lever to get high idle*rpm*but don't even think about touching anything else.

If you have the Lehman 120 you should be able to get 2650 rpm at high idle which means full throttle in neutral. Max (rated) rpm under load is 2500.

If the above doesn't appeal to you, get a mechanic. You can hurt yourself and the engine if you get governor adjustments wrong.

RE: real world fuel usage 120

It really is no more difficult than adjusting the throttle on your lawnmower.

It is essentially the same but anyone messing around with the governor adjustments on a diesel must understand that tweaking screws without a clear understaning of what those screws do can lead to "issues."

*I'm with you Carl, 'issues' is a worrying thing.The big problem* with issues is you don't know you have them till it's too late, and usually there is no way back, and any attempt to go back,*leads to dare I say bigger issues.

After reading all sorts of advice in the forums about mechanical issues, I hazzarded an opinion to my long*suffering *mechanic as he was working in the deep recesses of*Sarawana's *engine bay, a head appeared sandwiched between the transducent filament**0 ring*that triggers the biostatic equaliser for the thruster drives, or some such thing.

He gave me one of those Clint Eastwood looks,said nothing and disappeared back into the engine bay.I was lucky that day, I had dodged an issue.

In all honesty, I'd rather look at the steel Coot than that mud hen in the slip.

Agreed. *We've got fifty billion coots up here, thirty billion of which live on Lake Washington and which obscure the scenery when you drive across the 520 floating bridge. *Speaking strictly for myself, I'd prefer to see just about anything other than another damn coot-- which is the world's second dumbest bird, by the way--- when I look at the forum.
