This is one of the best explanations of how they work I have ever seen. Great video. Thanks for sharing.

[duckingtonedits]

This is absolutely without a doubt the best video I've ever seen regarding the basic working of a two-stroke engine.

[glitterbrains]

Wow! You actually cut one in half, that's really great. I'm not exactly new to this stuff but man, thats really above and beyond. Learning tools like that are completely invaluable. Cut aways are probably my favorite tool for engineering explanations, I'm really surprised this is the first time I've seen one of these China girl/Russian type motors cut open. Very cool, sorry for the super long comment 😅 definitely got a subscriber here lol.

This explains the characteristic smell of the two stroke . Some of the raw mix excapes thru the exaust .sweet! Thank you very much.many many years nobody could tell me!

[geraldmurillo]

My grey area with the 2 stroke began with the f/a mixture compressing underneath the piston and I never understood how it got into the combustion chamber. I never knew about the transfer ports. So thank you for this excellent demonstration!

[gotchurebeacons-gaming]

Great video! An awesome way to see the steps of the combustion series and pathways. In regards to porting, and perhaps you plan to touch on this in future videos, is the manifold ports. On your cutaway where the intake manifold marries to the cylinder head intake port, there’s an obvious “step” at the bottom that looks like it may restrict a bit of the intake gasses. I hope to see more videos that show things to look for on our China Dolls. Thanks again, bud!

[christopherbozeman]

Great visual aid. I just watched your porting video and it makes more sense now that I see the timing in action

[bernardosuarezcretton]

very clear and with a lots of tips to work with

[MierCatCustomz]

Very informative, thank you for posting this info !

[gospelninja.]

fantastic visualization! you gave me what i needed to know. now im changing my bearings, trueing my piston, trimming the skirt for max airflow, then porting my intake and exhaust, and now jetting... boy, i have a lot of work to do. im still more interested of timing. and i have yet seen a video of the benefits on widening or cutting deeper. so im still on the fence on it. for now i think what i can do will help it tremendously possibly giving me 40mph on my 80cc zeta motor.

I want to hear him say "inconceivable"

Awesome video sir

[englebertsingco]

boss i am also user of this kind of engine... and now i learn from you that how is really work. thank you boss...

[kurvaonwheels]

Excellent video. thank you.
2 questions: why do I see people drill holes in a new piston, and if it is necessary, why is it not drilled at the factory?

[bertyjustice]

excellent video. When the intake stroke pulls the fuel in is this a one way valve

[Jay-trts]

I am getting ready to replace my china bearings with the amazon ones you recommend. I have searched all utube videos. I know to use a arbor press on installation of bearings. Installing the oil seals not so much... Install them dry? Use oil? The 66cc Million dollar question I think only Eugene can answer. A bearing seal replacement video would be epic from Hughes Motorized in the future! Thank you

[MrMohamed]

How can the piston go up in the compression stroke even though it is a single piston?

[MoeLarrycurly]

And I'm trying to understand the Reed valve but I think I know when the ignition charge is put into the crankcase which is oil and gas than the read shut so the air doesn't get forced back to the carburetor I think that's it

[MoeLarrycurly]

I'm working on a non running Honda Express 50 + am trying to learn and understand the two stroke.. I have basic knowledge of the 4-stroke as a ride a motorcycle and have to fix it frequently.
