Stihl ms231, ms251, ms271, ms291, ms311, ms391 limiter removal

This is by far the best method for gaining full adjustability on those carbs. Thanks for the stellar video

[@mooregoodink7734]

Brennan, Thank you for this valuable information. Your kindness is much appreciated. I aligned each little groove with its corresponding limiting ball as you suggested, marked the center of each ball with an automatic center punch and using a 3/32in drill bit carefully drilled them out. It's difficult to see how the manufacturer gained an advantage by altering the carburetor in this way as the internals were caked with dirt.

Great explanation. Honestly I never realized there was a 2mm allen head in there. I've always drilled them out. Yes, those pins are hardened, and occasionally the bit will drift. Going forward I'll be doing it your way. Much cleaner. Thanks Brennan.

Thank you for that information, it may come in handy, I have the MS271, but I have not found the need to make any adjustments beyond the limits

A wise man, giving away free knowledge.... is a good man! Just my worthless 2¢

[@stevemcdowell2019]

Again Brennan, you the man!

[@tazman-kennyfuller]

Thank you Brennan. You rock. 🌲❤️🌲👊🪓

[@chrisbiltoc456]

This is the best way to do it. TY

[@ClintsHobbiesDIY]

Good to know even though I don't have any of those models.

[@jjm3254]

Great tip. Thanks.

[@G-PA-2795]

Good info Brennan

[@justinweaver8107]

That is ridiculous how they made those so hard to adjust.

[@Super-Dave-Outdoors]

I ground a slot through the pin with zip wheel on the one i did. Didnt know about the allen trick.

Tnx man !

Got your saw to start smoking. My plug too clean worries me.

[@jonathanglanville7953]

When I tried to back out the adjuster like you showed, it ended up breaking the plastic piece that you showed in the beginning of the video. Any tips?

I just drilled my ms271 carb plugs out today with a 5/32" bit, it drills easy its just aluminum, i adjusted it better than when i bought it new, my low idle was too lean ...
