I have a brand new B2650 and I'm wondering what the correct "min." engine speed is supposed to be?? The slowest engine speed is about 1120 rpm....what is the slowest speed supposed to be??
Thanks

Newer BX series idle and 1400+

I think the B7100 is close to 1000, mine has a tach. If I try to get below that get pissy and then cuts off (fuel is shut off) but at 1000ish is purrs.

I would say that 1100 is good;):)

Generally, the smaller the diesel engine, the higher the idle speed. My B26 idles at about 1050 and is fine at that.

I have an older B-6200 and warm up @ 1200 for a few minutes then run it up to 1600rpm for a few more. After that it's WOT baby!!!

The idle speed on mine is the same as yours and is correct.

The low idle spec is listed as 1100 rpm.
So 1120 is as close to perfect as you get.I wouldn't want it any lower as the oil pressure is only about 7 1/2 pounds at idle according to the specs.
