Injection pump altitude adjustment?

SDLars · Oct 25, 2013

Was just paging through the big 400's service manual and saw a reference to adjusting for altitude if you're operating at over 3000'. My 400 hasn't been tweeked since it lived at about 1200' and it's now at nearly 6000'. Book says to talk to the service specialist on what to do. Turn down the fuel? I'm no injection pump specialist by any stretch so I thought I'd see what you experts have to say. Thanks!

Yes, max fuel should be set lower for higher altitude. If you can, reset it lower to just see a light haze exhaust when under full load.

Will he need a special tool to do this and how is it done

I always thought that was an attitude adjustment.

"Attitude" adjustment kept running through my mind as I was writing it

. I might even consider myself somewhat of an expert at that!
