Any of the non m-tronic 261 carbs should work. Stihl used several different part #s over the year. I currently have s178d and s211 zama/stihl OE carbs. Stay away from the cheap aftermarket ones. Check eBay for a good used OE; I’ve had great success with those, usually $20-30. Also, be aware that the rebuild kits on eBay currently are the wrong ones for these carbs. Amazon has the correct ones…and cheaper.
Thank for the reply my issue start couple of thank after i rebuild with cheap kit. Found a brand new oem carb same number of mine but it 125$c do you recommand try an oem rebuilt kit before?
I’d replace the fuel filter and fuel line also
I replace the filter but not the fuel line seem to be soft found today leaking fuel from the carb and restricted fuel tank vent
Do the WHOLE system. AND pressure and vacuum test. Or just guess.
Just throwing it in, but I got a MS261 for free because the decomp valve was leaking and the saw had no power.
Why not fix the leak?
at least pinpoint said leak and figure out if it is fixable.
Yesterday fuel seem leak from hi/low needle clean the housing and run couple minute remove the carb fuel leak from the diaphram side steel plate 1 of the 4 screw was loose 
Probably too much beer when i rebuilt the carb. Cant wait to retry it it was the problem

Air leak at the needle screws usually means replacing the carb.
