Re: [DML] rpm behavior

[Martin Gutkowski <webmaster@xxxx>]

Just give this a try - it's easy enough to reverse.

Back off the rear two brass screws by 2 turns, then back off the front 
one by 1/2 a turn. This will give the engine something to breathe before 
the idlespeed can "catch up". If it idles too fast, snug the front screw 
down a little more - small moves on that can create big differences in 
engine behaviour.

Although the DMC manual says not to use the brass screws, the Swiss 
manual fo the Renault 30 , which used the same system, describes a 
procedure for setting everything up with the idle speed motor closed, 
getting it all working on the screws with the engine under no load. The 
ISM then reacts to positive changes in load only.

BTW I assume your 7500 was meant to read 750
