Astonishing really, your a genius man, and a nice one

Great explanation

Brilliant explanation! Thank you.

You are the engine doctor, i never figured out how my generator was able to keep constant RPM, you solved my mystery. Amazing presentation & well done Sir 💯

Great explanation of the system thank you for sharing!!! Somehow, I heard anti-gravity in your explanation somewhere. 🛸🛸

Very impressive explanation!. It explains so much very clearly! More than just spark plugs, electrical theory in general!Thank you very much for your hard work!.

@2:46 - The plastic Gear- I've always wondered what it was!! Silly me I thought it was the safety device when one hits an above ground root or something with the blade- it shuts off the engine. Thanks. I take apart mower engines for fun and Aluminum during the Winter. Thanx Mate!!!

I'll never own another husky, biggest pos

excellent!

Well done 👍👍👍

Thank you so much for this! I’ve never used a chainsaw, and my dad passed so he can’t help. You just saved me a LOT of frustration!

If you were my teacher in school I would have actually learned something 😂❤

Good explanation 👍

Awesome I'm 39 and never had a clue how that worked

What would happen if the metering diaphragm gets stiff or harden with age? What symptoms would be experienced when trying to start a chainsaw for example? Thanks for a great video.

I am amazed that it is effectively the same system used in the earliest steam engines.

So simple but so complex!!!

Thank you

You are too much of a fvcking genius !!! Thumb up sir ….

oh, yeah YT is an open source high school for DIY enthusiasts thanks for sharing, bro'

You are a great teacher

This is one of the best videos I have seen on a two cycle fuel system! Every well done with common problems found. Thank you for putting this together.

With small engines, there is no oil filter, so Non Detergent oil is used as it allows the soot and particles to fall to the bottom vs automobile engine which has a paper filter so Detergent Multi grade is used to keep the soot and particles in suspension and be trapped in the filter media I have seen equipment still running okay with the wrong lubricant and even chemicals that were not oil. Something slippery.

These screws are the worst design ever. I have one on my motorcycle Mikuni carb, on the bottom where you can't get a screwdriver in anywhere. Tweaking it clockwise or counterclockwise really doesn't give you a lot of feedback while it's running if your rich or lean. I just try to get it where it won't stall out when you twist the throttle. The real, real, real problem is the Pilot jet, which has the smallest hole ever in the center and gets clogged all the time on my bike, even with a fuel filter on, and even with a surgically clean carb. Worst... design.. ever.

Saya baru saja memperbaikinya... Dan telah berhasil bisa digunakan kembali beraktivitas

Thank you, for a very well compiled and great explainations on the video.

great video thanks

This is a wonderful and very clear explanation. Now, the problem I am having is: I have an old Briggs & Stratton engine on a finger bar mower (from about 1990), and this machine's diaphragm carburetor has a slightly different setup. The spring, indeed, sits in the lower part of the assembly (in what is part of the fuel tank, actually), and presses the diaphragm pump part up (!), not down. And now I am puzzled how this works. Any idea?

Hi there, great channel, love it - in it's entirety! One question - My saw keeps wetting the air filter - it's the lower third of the filter that gets wet.. Why would this be? I don't see any obvious carburetor leak ...

Makes sense

Throw that plug away, it has carbon build up on it, carbon conducts electricity, the spark can bypass the gap though the carbon build up when the plug is in the engine under compression, if the engine runs with that plug, it will probably have a miss under load and a poor idle.

Beautifully explained 👏

Thanks. Excellent

This information came out of practical experience!

Qué carburador es más mejor walbro o Zama

Use what the manufacturer recommends. It is that simple.

Great video. It's just mind boggling why anyone things governed throttles are a good idea. I promptly rig up a manual throttle control on mowers I get like the good old fashioned mowers used to have.

I took one apart for the first time to clean it without any guidance and now it won't prime anymore.. Watching your video made me realise that the fuel line blows fuel instead of sucking it.. wonder why is that.

Another great learning session!

Great video…….you really are a specialist when it comes to these little carbs!! Love the explanation drawings. Keep up the amazing work!

I've replaced alot of coils, always thought melting from heat or rust inside,, thanks

Sometimes the spark plug will give spark but it is a false spark.change out the plug and the machine will fire right up.i have seen this condition many times

I have a Toro that doesn't have the push bulb i can not crack it up

Hi Craig I was wonder if you could help me? I've just brought the ERBAUER ECSP41 40CM 41.4CC CHAINSAW it seems to be a ok made saw, but i'm struggling to understand the choke. The instruction tell me to start or attempt start the engine with the choke closed. if that fails start with the choke open but no mention of closing once warm. but most confusing is when the engine is off or running and i pull the throttle it automatically open the choke!! i.e choke is alway open when running i'd really appreciate any advice regards jack

Id much rather have a manual throttle lever.

*Thank You* so much for this video. The primer bulb is less than 4 years old and the damn thing takes between 30 and 40 seconds after pressing it in before it resets for press number two and the same for press number 3. That red crap they use for the bulb is a pain. The primer bulb on my Ryobi line trimmer is older and is still like it was when new. *Thanks* again. Greatly appreciate this. 👍

Tried to adjust a new carb on a 20" chain saw. I replaced the carb, and have been unable adjust. Gotta go back in and check my work, break it back down. Your videos add value to our processes. I would get discouraged but it is time to find out what I did wrong. Your videos are great.

Y si no prende maistro ?
