no more exhaust problem

The exhaust is all fine no water all is well so lets remove that from the equation. Mechanic is lookin at the on engine fuel handling ie injector pump, governor, all fuel system checks to fuel filter on engine ok, clean clear fuel and new filters. I like the anchor idea 😂 ya never know

Do you have two sets of controls? Upper and lower? Does it do the same from both?

When you start it can you reach down and use the actual fuel lever on the engine and get proper response?

I have seen the morse cables come loose and be erratic. Both the core and the cover must be fastened to work properly.

It makes a difference if you ha e dual stations. If the upper and lower are acting up means it could be the cables all the way down. But if it's just the upper station then it's the cables between the upper and lower. If you can operate the throttle ok right on the engine check cables.

Beginning to sound like you might have an issue with your injection pump.

thats what we are working on now

Thank everyone for the help, cables pulled checked and re lube. Talked to American Diesel and the next process is checking the hangar in the injection pump to ensure the hangar is moving freely on its track. That hangar follows the action of the throttle cable so it it the next device in line. Again thank ya'll for the suggestions and all will end with a good solution to keep in mind when it happens to someone else.

aha moment

The rack inside the injector pump is the culprit. After hours of downstream verification the rack is the last thing in the line. After that is injectors which are ok. Wishing all a very happy turkey day and a full belly. Now finding a mechanic that can do it. I'll post the outcome when it happens. Thanks to all for the help.

Peace

Thanks Reissue for letting us figure this out with you.

Good to know it can happen like this.

If that was indeed the problem, could it have been just a coincidental failure, or could it have been caused by the rapid deceleration?

I have seen a plunger stick in a FL and that stuck the rack. Took side cover off pump and with a little pry it unstuck. Back to running. As far as I know it never stuck again.

I once had both injector pumps go bad at the same time on start up on a twin engine 36' GB. I mean what the Hell are the odds of that!?

The rack is free and they have full travel, just not by the throttle. The injector gods said it just happened, probably age and abrupt manipulation.

So...there yah go. If something happens with sudden throttle movement, when all fine before, look to the things mechanical that link to said throttle assembly, sounds good logic.
Works for me...
