hi, does anybody know or where too get carb settings (high&low screws) or a rough idea so i can get it started after many years of idleness.

hi tree fella

the high is one turn

low is one & 1/4

that is the book setting might have to fine turn it abit,some say just one turn each & work from there just strip & clean check diapham etc if been stood.

hope this helps

any luck getting your saw going ?

yes, cleaned all old fuel out and refilled with fresh ,set carb as book said...... but when hot after sawing it ticks over nice for 99%of time then the other1% it stop dead and takes 3-4 pulls to fire again then its ok till next time. any ideas?

[shropshirestars]

whats the 1% doing as an old stihl when hot & stalls can be very hard to start (3-4 pulls is pretty good on restart),adjust the idle screw a tad it must be warm to do this,the idle screw is the brass one on the side of the carb turn it in very slightly it will alter idle speed to stop engine stalling .try this & if no joy let me know

good luck

hi, dont know if this may help but both my 75 & 76 both suffer with idle screw moving with the vibration, ive used threadlock on both which has worked so far!!!!!! only use a 'mild' threadlock thou, some of them are designed for permanant situations!! ive just bought an alaskan to try, let us know how you get on,, cheers
