Stihl ms 211/c circa 2010 replacement carb

[John Rainford]

Looking for an after market carb to fit my trusty old saw and there lies the problem. It's a Zama c1q s119B. From my research it would seem that there was not an after market carb produced for this one. I don't want to pay £100 for an oem carb for an old saw. someone recommended Rowena motors, but they were unable to help. I'm thinking that there must be another after market carb which will fit my saw. There seem to be some that look exactly the same as mine. I'm no expert so don't want to take a punt on one. I've had lots of help on here in the past from spudulike and others which have helped me to keep my saw running well so i'm hoping someone might have an idea how to solve this problem.

 

A little information which suggests to me it might be a carb issue. It will start and idle one day, but the next day it might start but then stall at idle after a few seconds or perhaps a minute. I can keep it running with some throttle, but then it will cut out if I take my finger off the throttle. Adjusting the L screw in or out does not cure the problem, neither does turning the idle screw in to increase the idling revs. If I turn the idle screw all the way in the chain does not run on the bar as I would have expected it to. It's also producing a fair amount of white smoke on starting up and it's burning through fuel very quickly. On a day when it does start and run, there is no issue with bogging on acceleration. Any help would be gratefully received.

If you buy a typical cheap ebay 'aftermarket' copy carb, then buy two or three while you're doing so, as sure as eggis is eggs, the first two will be shite...unless you are lucky.

You haven't mentioned piston and cylinder condition, easy to check and if fubar then no point buying a carb.

Scrap it , could be opening can of worms and its a cheapo saw, decent carbs are not cheap and ud be half way there with labour for a new saw ,

I did once purchased a genuine Zama carb from China for a 201 and 150 for something like £15 off eBay. Worth a good look.

From the description, it sounds like the saw is running very rich so...

 

Blocked air filter

Choke stuck partially on

Check valve stuck open

 

Assuming the H adjustment is set correctly!
