- Part 3 of trying to get my LEGO Briggs & Stratton engine to run off a vacuum.
With the help of @xmysef4920 it finally runs again! What did it take to get here? Watch and find out!

Thanks a lot for the shoutout! I was honestly a little confused why it didn’t run faster…
Well, I hope the help was good enough anyway! Good video
It's more than good enough! Thank you for all your help!
Hm wow so glad it actually got it running good. Nice job mysef!
Still don’t know why it isn’t running any faster? Hm.
@@smoothshell7397 He doesn’t have the disc pieces. Trust me when I say we tried everything you can think of lol
@@DeltonAdamsLEGO I tihnk one thing that could help is opening up the crank case, It looks like the crankcase us fully closed so it compresses and make makes a vacuum everytime the piston goes up and down, Also the air leaks around the piston during the up stroke so the pressure would be even lower in the crank.
@@dividingrain1907 the crankcase has a large hole in the back, you just can't see it. It had a hole from the very beginning
You should call it the bricks and Stratton!
That is so good 100 percent!
@@BeamNGPlayer007 thanks
1:20 the music and engine are perfectly synchronized!
You can try to make the flywheel lighter and smaller, because lego vacuum engines are running with small flywheels.
And i think when this engine runs with that really big flywheel with a smaller one it should run fast.
We tried that multiple times and only once did it run again
I know nothing but it looks like the 2 wheels on the flywheel look heavy but idk any thing
the only engine i made is just a mock up not a vacuum
It's actually not as heavy as you'd imagine
havent even watched the video yet but i’m assuming thats so that the motor operates a lot smoother, the momentum of the flywheel should keep it at a more constant speed instead of having hiccups
Keep the great work! I made my own lego turbine (i kinda cheated because i didn’t have the pieces so i used tape) and i uploaded it to youtube. Your vacuum engine is incredible.
Imagine making a 4cylinder engine like this, what a cool design.
I think you'd like this video. Someone made a REAL I4 Briggs!

@@DeltonAdamsLEGO Impressive! Just like a factory engine. And keep your videos coming, i love builds like this.
I think it would help to make the piston thinner to reduce friction. Also check the watts of your vacuum, that might be the reason because of that person’s engine running way better.
Well, about the vacuum wattage, he did purposefully have to restrict the flow to make it run better.
Yep, the engine doesn’t need much vacuum at all, infact mine runs great by just manually sucking through the vacuum side port
Now make round piston Lego vacuum engine
I might try that!
you gotta use the pullcord on the side if you want it to run properly
I would, but it's just for decoration!
Awesome engine and video! 🔥
Some more suggestions
1.Add silicone oil to all moving parts. WD40 would also work but would probably ruin your lego's (stains). Although it may not improve the speed at first, it will improve fluctuating vacuum.
2.Get some eatable school glue, and paper. Before you stack blocks where the piston and chamber are add paper and glue (make sure to punch out the holes) to act as gasket for the blocks.
3.I can also see a space where the window is for the piston. Suction could be leaking out.
The main thing an engine needs, any engine (Gasoline, steam, etc) is Compression. Compression requires a good seal. Compression is what pushes the piston down, you are compressing the air with the vacuum, and if there is not good compression it will have bad torque, bad torque means it won't be able to handle forces very well. Either remove the flywheel and add weights on the crank (if you just want it to run) or seal the whole thing up and smash a big fly on that baby.
Those are good suggestions, but this isn't intended to be a permanent build. I reuse a lot of my bricks for other projects. That's why I didn't want to lubricate it or glue parts together. But thanks for the tips!
@@DeltonAdamsLEGO I didn't mean glue the legos itself together. Eatable school glue has good sealing properties, while still being.. Not glue.
@@Laqota ah, ok. I still don't know about that. I really wanted to keep it as stock as possible. I feel like doing that would be like cheating for me
Runs now waaayy better then before
Keep it going😁
A functional pullstart would be awesome.
So, when I was designing my new one, I originally wanted a pull start, but I couldn't get it to work when I installed it. No clue why it stopped the moment I attached it
Very nice! You did a great job!
Yeah I think you need a smaller flywheel for less drag and less weight
We tried that. We only got it to run once with a small flywheel after a ton of testing
If you make both of the cams I sync with one port you can use both of the valves as one big valve it should work
I did that for the first version, but people were saying I needed an intake port so the cylinder can get air
Maybe use the long duration cam for both valves and 90 degree offsets and a lighter piston and two ports that should work
Well done 🤝
You Can reduce the flywell to add more RPM.
It's not that simple. We got it to run once without the large flywheel. And we tested a lot
yay
Is there a spring to close the valves?
There is for the non-vacuum side. The vacuum side doesn't
I like these kinds of videos
I'm glad you do!
How are u so under-rated
Nice
ayeee🎉, whats next?😏
I don't really know right now! But it'll be something good!
@@DeltonAdamsLEGO h- yeah dude
U need a faster vacuum
I think that my vacuum might actually be too fast...
Hahaha i ruined the 69 likes
use olive oil to make it run smoother
I don't believe it's friction that's the problem
Yeah highly doubt it, i’m soon posting a video of mine after lubricating, really doesn’t improve the rpm that much…
