STIHL’S OFFICIAL 2 STROKE CARBURETOR TUNING PROCEDURE.

Adjusting the carburetor on a 2-stroke engine can seem challenging, but in this video, I'll simplify the process. Whether you're working with Stihl, Honda, Husqvarna, Echo, McCulloch, or any other 2-stroke engine, including 4-mix engines, the adjustment process is virtually the same. By following this step-by-step tutorial, you'll learn to adjust your carburetor with ease, ensuring optimal performance and preventing potential engine damage.

You have a talent for explaining thing's.
Also nice to see someone laughing and smiling as much as you do.
Keep up the good work

I had just watched your video about the accelerator pump I didn't know existed in my Walbro on my Poulan chain saw. I checked and it was in very good condition so I just made sure the passage and bore were clean and reassembled the carb with new gaskets and needle and lever. Now you explain this settings so that it is easy to follow and it works. Thanks for doing these videos and sharing your knowledge with us. I'm almost 80 and have worked on a lot of different engines both gas and diesel. It is clear instructions like you give that makes things easy if people just try.

I wish you made all the instructional videos that I would ever need. Very well done.

[williamevans]

Just found your channel and subscribed, you do a great job of explaining how all this stuff works, thanks alot for all you help.

[projectdelta]

What a great in-depth explanation and attitude. I don't normally sub to people doing random videos ill only need help with for a moment. You are an exception. And to me that is saying something

The critical factor that helped my understanding was to remember that lubrication is mixed with the fuel, so lean delivery is dangerous to the cylinder wall. So, for both H and L, this tuning algorithm is set up up to run a little on the rich side to ensure adequate lubrication and slower rpm. The second point is that when you're on the rich side of the equation, increasing fuel delivery consistently lowers rpm. I love your remark about building in a little reserve to that setting. So, when fuel changes, air filters are clogged, and ambient temp changes you've got reserve that prevents the engine from creeping into that territory of lean cylinder wall damage. I guess this is also why environmentalists don't like 2 strokes, since perfect stoichiometric balance is too close to the threshold of engine damage.

Great Vid Tom. Only change I would add is I allow a 5 minute warm up, especially in the winter and in freezing conditions. Also, these mixtures will vary with changes in temperature, humidity, and elevation (0xygen content in the air). Don’t be surprised if you used this procedure on a hot summer day and then in the winter when you want to use the equipment it starts acting funny. Again great content Mate!

[williamb]

Fantastic video! Thank you so much for the great explanations!

[larryoakley]

A bit overwhelming at first but after a few replays, I was able to get the whole idea. Thank you very much !!

[StuartG.Kizomba]

Thank you, I've been doing it this way for many years bit this spelled out exactly why and actual steps that I never really thought through...thanks again

[DtKnize]

Great video, thanks for all your efforts to help out the general public.

[stevenertle]

It can be a little confusing, but you did explain it very well, thank you so much

[johntrainssmith]

Great video Tom, well done. I guess its easier to explain with a video than over the phone hehe.

[richardblack]

really simple to follow.. been struggling for some time.. Thank you.

[frostieone]

Good clear concise explanation! Well done! Thanks Ken

[DrivelineMaster]

I have never worked on small 2 stroke engines but I have rebuilt more than my share of automotive engine carburetors and I enjoyed watching. These carburetors are much simpler than an automotive carburetor.

[patrickwhalen]

Always learning from your channel, thanks Tom. Great content!

[aSpyIntheHaus]

Exceptional video mate. Really good work

[lynnesnowball]

Mate that 011 is bloody gorgeous!! Currently rebuilding an 009L and 011AVT myself😊

Just tried several videos and this is the one that worked on my 201T and 461R. However, even with my H set all the way counterclockwise I still think my max rpm is a tad high. My Tach was one off of amazon and couldnt get a solid read of the high rpms as it jumps quite a bit past 9000rpm but still seemed a bit high. Either way, thank you a ton for this video as it is the only one that took care of 95% of my issues.
