The sandblaster was from this TKOR video: • We Made a $5 Sandblaster
Trying to build a go kart, and it's led me to discover a plethora of underrated small youtubers and I've been binge watching wayyy too much. Subscribed!
EXACTLY!!!
That sand blaster sure beats a wire brush. I'm impressed.
i’ve been trying to build a go kart with a vertical shaft push mower engine and this is exactly what i needed!
Great quality, this video really helped me use my engine for a go-kart. Thank you!
Btw how does the kart idle
Clutch
We gotta get you a better camera my friend! Awesome video!
Thanks! I have a better camera, I used my phone for this though because I didn't have the other one with me.
vertical shaft engines have a much lighter flywheel as they rely on the blade for extra weight
Just the rotary mower engines. Could use a cast iron flywheel from a pressure washer engine. Those are pretty easy to find.
Mine is an older model so it has the same flywheel off the horizontal motor
What’s awesome is that’s the exact same engine as mine so I can follow along
Thanks for the video. I have a discarded mower with a B&S 6.5hp engine that I'm intending to futz with one of these days. I look forward to seeing what you do with this, and (maybe) what kind of longevity it has with the improvised oiling.
I have that engine too I’m gonna make a go kart
How'd it work?
@@awesomewolf7197 haha, life gets in the way again!
What size crank shaft outer diameter does a 25 horse 2500 Briggs and Stratton have
excellent work, now, how much oil you did to the engine. Thank you
I never did anything for the valves or breather, just a slinger bolt on to the crank..is all I did . And I just dumped a quart in never care to change it ever and my boys rip on that mini bike ..but maby next time would be good to do all that .oh and I just screwed a screen to the back of the carb for performance reasons..they got way more power than a traditional 5 horse side motor in my opinion
Did as you say many years ago and it ran for ages without any trouble!
use a sodder bolt to fix that petrol leak on the tank in the join ,cool viedo well done
I love the video but you were saying that you filled the whole you drilled so do we just ignore that step and hope that the springs get enough oil?
Don't fill it completely, he just drilled the hole waaaaay too big. If you drill a smaller hole from the beginning you won't have his problem.
If you look at the oil fill on a horizontal engine the oil level is much lower then that. Think you had it way over filled. You could drill and tap a small threaded hole in the side of the case to the correct level. When the oil gets to that level it will start to flow out and you k ow your level is correct. Then put the bolt back in. I guess you also ran into issues with mounting it too?
How would the motor idle for a kart
I'd do this but how do you change the oil, you would have to take it off put to horizontal and change it.
Why not using 90 degree transmission gearbox?
could the oil hose from crankcase be used to oil the ventil shafts
THANK YOU SO MUCH SIR
hey how would you use a right angled gearbox on a lawn mower to put on a go kart
Don't bother, it's too much work and converting it or even buying a new engine is cheaper.
Oh also, another thing did the shaft down near the mower blade have a key screw in it to hold the blade mount to the shaft and howd you get it out if you did have one? Thanks
This one had a regular bolt in the end holding the blade and adapter on the shaft, once the bolt was out I used a 2/3 jaw puller to get the adapter off. Even with that it was kind of a pain.
How to add speed control?
I used a universal lever control cable (this one, in fact : www.napaonline.com/en/p/BK_7311110?keywordInput=7311110) for this build, but this engine is being used in a static fixture rather than a go cart.
All well and very good but why not simply add a gear box that is 90 degrees
Direction change instead of tampering with a good running engine. Often U
can find them on the mower deck of riding tractors and or pulley systems on the same does the same action .
Can a external oil pump n tank be added to the flywheel?
I'm sure one could, I think personally that would be overkill though.
Now you can power your Yugo. I want to do the same thing to an engine of mine I have a mower grave yard and want to make a band saw mill.
Hey Riley, during the 2nd act, you said there was a hole in the casing that fed to the breather tube and hopefully that fixes that. But I don't think you gave your solution. Did you fill it with JB? I have oil pulsing out of the carb at the air filter box side, when i shut the engine down.
Any thoughts on why ?
Thank you for the video and your time,
Daniel from Phoenix, Arizona
Are you referring to the one I drilled? I did fill it mostly with JB weld, there is still a small pass through. It does still pulse oil out of the breather. My theory is that because the compression is so low, a lot of it must be getting into the crankcase and pushing the oil out.
@@rileylamborn1846beginning at 22:53 after you reference the hole you drilled.
I haven't done anything with the tube that crosses to the other side of the engine, the only modifications I did there were filling the original hole, drilling the new one and then filling the new one mostly up. Though restricting that tube may help reduce the amount of oil coming out.
@@rileylamborn1846 ok, thank you for clearing that up for me! Im trying to figure my same issue. Thanks
What do I do to get a horizontal shaft ready carb for a 300 series briggs? I am going crazy trying to find one
I'm not sure on that, I've got one of those engines I've been meaning to tear down and see what it would take to flip but haven't yet. On the build I did here I was able to use the same carburetor, just rotate it 90°.
@@rileylamborn1846 the 300 series carburetor is waaaaay different than the one you used. I found your video so helpful.
I'm glad! I'll have to look at my 300 tonight and see if I can think of anything.
How did you attach the governor arm to the crankshaft for a splasher?
I drilled a hole in it and it's held in by one of the connecting rod bolts.
What did you guys do for oil lubrication on the crank, don’t have access to a welder sadly
You mean like for a splasher? I cut and bent the lever that connected the governor to the throttle linkage, drilled a hole in it and held it on with one of the connecting rod bolts.
It was the piece that I start sandblasting at 2:04, and you can see it attached to the crankshaft while I still have the engine apart at 13:04.
Riley Lamborn ok that’s awesome, how has it been holding up, hasn’t rotated hopefully and hitting the inside of the case?
Not that I've detected, but I haven't run the engine a whole lot since then. If I remember right, I left the end where I cut it squared off and put that end against the rod to keep it from rotating.
Riley Lamborn thats perfect yeah, what about the governor splash arm that’s inside most on the governor gear? Can you use that too?
how do you get the blade mounty thingy off mines like really on there
Persistence and cussing. And a slide hammer.
Just found this video... little weird that you mention Grant Thompson, lol
Tried to get through it but ended up puking from motion sickness
How did you start it so easily? Mine just snaps back the pull cord Everytime I start it and it has proper timing
what engine are you using ?
@@gabrielpichette7272 I'm using a Briggs and Stratton 190cc flathead engine. It's good now it turns out it didn't have proper timing. It never snaps back now
Did you check whether your flywheel key is not sheared? That's a usual symptom...
@@Merlogcz yeah it was sheared. Got it back the way it's supposed to be and it runs good and never snaps back
@@93jake81 that's exactly what happened with mine. I actually sheared the pin a few times before this was done.
How did you get the blade attachment off?
It was either a puller or a slide hammer, I don't remember at the moment.
how did you remove the flywheel and blade adapter?
For the flywheel I used a bolt type puller, I believe the holes are 1/4"-20 thread. Or that's what you're supposed to tap them to if they're not threaded yet. I believe I had to get a slide hammer involved getting the blade adapter off.
oh ok, thanks for your reply! what problems did you get while working on this? cause mine I don't have a material to remove the blade adapter. hehe that pesky adapter won't let me sleep until I remove that and continue working
If I remember right, I used a 2-3 jaw puller that attached to a slide hammer. I worked at Napa auto parts at the time and they had a rental set there I used. I do remember it being a royal pain to get off.
Would this same idea work on a 12hp flathead? Briggs of course
I'd imagine the concept would carry over, I'm not familiar with how the 12hp differs internally. On the outside of the motor you may have clearance issues between muffler and carburetor, so you might need to make an elbow or two.
Has anyone here ever did this with a v twin? I have an intek B&S 22 horse vertical that I could use to replace an onan p218g in a John Deere 318 garden tractor. Parts for onan are getting nearly impossible to find and what is out there is crazy expensive
Not that I've seen, so if someone has they must not have documented it. I'd imagine it can be done, the main thing I'd worry about is lubrication. Do you know if that engine has an oil pump or just a splasher? A good way to tell is if it has an oil filter it has an oil pump.
It has a pump, one late sleepless night I was going from forum to forum reading about it being done, it is fairly common in to go-kart world, at least from what I've read. There were links to websites that provide oil pans, electric oil pumps, intakes, and whatever is needed to do it. Of course it was very late, I was dead tired, and being about braindead by that time I didn't think to bookmark any of the forums and I haven't been able to find them again.
If I try it I want to at least talk with someone who has already done it first. I've searched and searched for videos like this but with a twin cylinder, either I'm not looking in the right places or they simply do not exist. When everything but what you enter in the search comes up in the search results, I'm thinking that I just haven't found the right place to look..
Very well could be. In the absence of a guide, I would think the most important thing would be to make sure the oil pump can get oil in its new orientation. Whether that means bending or making a tube to go to the bottom of the crankcase or opting for an electric pump, I'm not sure. Then next would be to make sure the oil can drain from the bearings properly.
I need to pull it apart to see exactly what will need changed and how, but I really don't want to rip into it without having what I need to do it right away instead of taking it apart then getting back to it weeks later.
One year later and no progress??? What up with that
I finally made an update! ua-cam.com/video/Hc6xqbFP-ME/v-deo.html
