I never knew the magic of the 2 stroke engine... ive worked on 4 stroke small engines for yrs as a hobby. These cutaway videos are amazing..youre an excellent instructor.. thank you...
Came here to watch to wrap my head around the 10° blow down numbers you were taking about on buckins mac 850. Thanks for this cutaway series. Thought I had a basic understanding of 2 strokes, but I was way off in my head. Had no idea what "transfers" did and didn't realize the fuel went into crankcase before being transferred to the cylinder. Makes so much sense now and I learned my one new thing for the day! Lol Thanks
One of the best videos yet on RU-vid you went where everybody is afraid to go or should I say they're trying to hold their secrets you helped out a lot of amateur Porter's everybody thinks it's a big mystery but it's really pretty simple been doing it for years again one of the best videos on RU-vid keep on kicking some ass
Hey Tinman. I'm just a homeowner that cuts wood for my yearly use at home. I have always loved learning and seeing mechanical stuff. I watch BBR also and Ironhorse. Have gained some interest in may fooling around with my saw or buy another to mess with and this was a fantastic explanation. Will have find Part 1 and watch it as well as other ones you have coming. Thanks for your work.
I'm just getting into fooling around with 2 stroke engine,and I love them, you have been a great help adding to my understanding of these fun engines. thank you sir.
I’ve learned more in the space of this video the one before about engines than I have in the last year! Knew so little about two strokes. Thanks! Can’t wait to watch more when I next have an hour spare 👍🏻 keep up the good work!
This is by far, the very best visual explanation of timing on a two stroke, and how a few degrees one way or the other will affect torque and rpm's. Super job Tinman. Tap-er-light, eh!
Excellent video and explanation ! It makes you realize how easy it is if you don’t understand a 2 stroke as to how badly you can screw up a porting job for performance unlike a 4 stroke .
Man thanks for this video! Absoluty great way to explain it! I am VERY Familiar with 4 stroke head porting, however I have been asked by many people to port a 2 stroke and I turn it down because I was not sure how that is done, I hav however done "Clean Up" porting but never understood the Port Timing and intake port timing adjustments. THis helped me a lot. Thanks again!
Tinman, this is the best demonstration I've seen on this. Between you and Ironhorse Im confident I can do a successful porting job. I have a 257 Husky but it's of the open port design. It looks different than what you guys normally do to Port the transfers. Thanks Mr. Tinman, Happy Easter.
Excellent explanation of intake duration and why it is important not to overdo the intake timing. Everyone who owns a saw and uses it professionally should watch this.
I achieved 360dgs inlet on a lambretta engine by fitting a Yamaha reed valve and cutting a boost port over the top of the crown. I swear that engine was smoothest single 2T I've ever ridden. No banging or delay. The power curve was as smooth as a upturned banana... It made 24bhp. Not bad for a 225cc that was 45 years old. Fitted kawasaki cassette clutch from a KDX as the best lambretta clutches all slipped..
Awesome explanation brother! I always love it when people explain what everything is and then give a rudimentary explanation of how changing a particular thing will affect operation. You're definitely helping me get the courage to start tinkering with saws, but I'll be waiting on some more info such as learning about squish and transfer shapes first. Keep up the good work!👍
Dude! defintely the clearest informative video on this topic out there! Keep up the amazing work 🤟 sorry iron horse! You guys should sometime to conjoin be a great episode 👍
Great job 👍 Tinman. With your visual cut away and great explanation, I'm sure anyone who hasn't worked on an engine before could get the hang of it. Really moving up in the world, we have picture in picture on Tinman's channel now. Pretty soon it'll be a white board and projector at the professor's Lol. Keep up the hard work and awesome videos! 👍👍💪💪😁
Great video, thanks for sharing. I use an old cut out spark plug and a DTI gauge through it for tdc. Also save ya plastic chopsticks for sticking down cylinders, they are great for pressing on parts that might get scratched.
Yeeeesssssss! More port timing!!! Thanks Tinman I really need to know this stuff so I can do some porting for myself. Your video's are great and the timing is spot on too. Be safe.
Thanks tinman, I didn't fully understand how to time a saw before watching the video but now I do ! Thank you . MY COFIDENCE LEVEL IS ALMOST THERE TO TRY TO PORT ONE OF MY SAWS ! Thanks again
Thank You for all the time and effort you put into videos like this! Truly amazing teaching and presentation skills you have! I already messed around with porting a baby Husky 40cc without a wheel mounted. Now I’m curious what the numbers are since it really pulls strong for a little saw.
You have done an excellent job in making these cutaway. You are a master teacher. The idea itself is excellent. You have made a difficult subject east to understand. I thank you and encourage you to keep teaching. The video is so good. What camera did you use?
You are the best, thank you for the education, I love your videos and I watch all the other guys too. August and Buckin and Reg coates, the very best,....
Nice, per Steve's shout out, Steve's small engine saloon, as I look through your videos, I decided to watch your video,Chainsaw cutaway #1 how a 2 stroke works!!, And then this one as. I already knew the two stroke cycle, so was interested on your take. But this video was very interesting in how port timing is so critical.
