sms630 idling issue.

HI guys, i have an sms630 and i have recently noticed the idling up on about 1850.

Now i know how to adjust my idling as i have done it before. (below/behind airbox. screw with 8mm open wrench, turning out to bring idling lower and screw in clockwise to raise idling.)

Problem: i can't seem to bring idling down! i tried the other way and it seems to be persistent on the 1850-1900 mark.

i had it down to 1650-1750 originally.(last year) but something is wrong.


any suggestions or should i just take it to my closest dealer?


i would appreciate any thoughts or suggestions. thank you!

check the fast idle/cold start lever and the associated cable adjustment.. could be over-riding your idle adjustment screw and not allowing any reduction in rpm.

ok. thanks fast1! I'm not sure how to check those but i will mention it to the mechanic as i plan to drop it off tomorrow.

I apprecaiate you responding straight away.

cheers.

by the way, why do you think this is potencially the problem? has this happened to you before?

Or could be the throttle overriding the idle.

yes... the adjustment knob that controls the fast idle cable slack has come loose and over tightened the cable causing the idle to increase beyond that which is controlled by the idle adjustment screw.

ok, great, thanks. noted.

Hey fast1,

turns out you were right! it was the cold start lever that went out of adjustment! thanks again for your input.
at least i was telling the mechanic like i already knew what was wrong so he wouldn't put one over me!

ha.

I came here to say what Fast1 said because I was pretty sure I knew that's what it was after only reading the thread title

that's cool! thanks anyway.

Just had the same problem. Idle went from 1700 to 2400. Idle screw adjustment did nothing. Found this thread, adjusted the cold start cable and problem solved! Thanks Fast1

Glad I could help.
