I really need to find neighbors like you. My lawn mower has a 455 Pontiac that needs some work 😂
😂
Funny, I have that same model!
you can face it yourself with a new round 8-inch medium grit grinding stone. heat it up first what he should I've done about 300 ° Celsius then let cool down first.
Reckon your lawn mower heads exhaust valve needs some stems seals about 8 in total then u be running tip top😁😁😁
Same!
I mean, this is probably the best condition that head has been in, ever.
Legend has it that mower now runs 10s 😂
That cleaning guy in the workshop really seems to be picking it up quickly. Top work.
Meh I think he's probably another few years away before you'd consider allowing him to start on the machines.
Lol isn’t that his dad
@@elicarter1356 Ha yes it is - been running it for like 30+ years
They oughta give that 'Cleaning Guy' a raise, he deserves it!!
LOL -- a complete head job on a $145 lawnmower. Y'all are great neighbors. This is the inverse of a Mustie1 repair :D
That’s a much bigger head than you’d find on a $145 lawnmower. Probably from aa OHV Briggs & Stratton 19 or 21 HP riding mower.
@@ellieprice363 it's Kohler head. Hard to tell the size. Because Kohler uses that head for about 10 different engines.
@@ellieprice363 Thanks Ellie. Still way above and beyond that head was probably truer when the shop was done with it than when it left the mill in Guangzhou
@@ifitsnotbrokenfixit1193 It looks identical to the head on my B & S. 21HP. I considered decking it about .020 when I had it off but decided against it. After 10 years it has served me well with only the broken compression release replaced. Uses no oil.
She's been overheated or gotten hot ,look at all that black around the exhaust valve spring area of the head.
Some is normal,but that's really dark.
That mower is gonna run better than fresh from factory now.
Probably gave her 5 more ponies with that head job
High compression will need 98octane and faster Footwear when mowing the lawn
As a fellow machinist, the "Safety Shake" is no joke lol
Was not expecting the YEET!!!!
Thank you for making videos. My grandfather was an automotive machinist but sadly he died of cancer when I was 8 months old. I love watching your guys videos to learn about these things and what according to my dad, my grandfather always wanted to show his grandson but never could.
That's a really nice story. Your Grandpa is proud of you I'm sure
hey, my dad was an R&D machinist. cheers to a dying race of absolute titans among men. Living in a world of grease, oil, and thousands of metal chips under your skin.
Never cease to amaze me how much DIFFERENT engine machining is than job shop machining. Similar precision just different procedures. Nice work.
Do a head on my mower, I used a belt sander and two quartz stones. And, after ten years, it's still running strong. I quite imagine this guys mower will run until he gets to will it to someone. Great video - keep em coming!!
In first corona year I did such kinda head for a friend . I installed 1.5 mm oversize super alloy on exhaust as old was worn, 1.5 mm oversize stainless on intake. Both bronze guides and ported both intake and exhaust port . Then planed to raise compression at least 1 point.... Now the engine runs very well and startermotor only gets it going when throttle closed as otherwise dynamic compression is too high...
Charged only couple of bux as the fun seeing him doing the lawn with much better track times and fuel efficiency is worth it. 😁
Install a compression release on the intake valve for them. That takes the strain off the starter, or your arm, when starting a higher compression mower. I had a tricked out walk behind mower when I was mowing lawns as a teenager. I did so much work to that motor it would make your head spin. My neighbor saw me pull starting it one day, lifting the whole mower off the ground if I didn't get the pull timed just right. He offered to help install the pressure release and boy oh boy did it make a difference.
@@eriklarson9137 Can't go back and video something I did 30 years ago.
My son and I spent years racing 4 cycle karts, mower engine work always involves hop ups.
You are lucky to have a very competent cleaning guy. I hope you're paying him what he's worth! ;)
Well, now you will be able to hear the happy sound of his mower cutting grass, and maybe some free barbecue next time !
The yeet! Got me rolling 🤣
The best engine rebuilt i have ever seen on a honda civic. Thanks!
I did this type of work right out of high school for a few months. I did really enjoy the work. Your videos show a lot of progress since the eighties, or possibly the shop I worked in didnt invest in cutters like yours. I do miss this type of work. The use of reference materials to find clearances. If its not on Google, a lot of people couldnt access the numbers needed for head repair. Great videos yall.
That mower is going to run better than new! Great work guys. 👍🏻
I love seeing that grinder deck the heads. Perfect surface afterwards
I have seen many of those Kawasaki engines with warped blocks from overheating, people won’t clean the trash out of the cooling fins.
Very true
Great little video, I know it's only a tiny head and wayyy overkill for your neighbours mower but you would be terrific neighbours to have and is a good deed.
This sure is a "No job too small"... Nice to see something repaired rather than tossed in a dumpster.
This most likely cost more than a new head.
I need you for a neighbor. I worked on small engines for 20 years and those valves will probably see better than did new. Nice job.
Solid work, i bet your neighbor really appreciated the help.
I always wanted to bring the compression up on those engines. Most have a decompression provision so lets bring the operating compression up to something respectable. Other thing I always wanted to do was balance the rotating assembly.
One thing I hate is when they say if you want to see the long form of this video you know where to look, but some of us are so old and decrepit we don't know, so thank you for putting a link in your little one minute short video.
Better then new. Wish you were my neighbor. I have a bunch of Briggs cranks from 10hp engines that need work.
I've watched many of your videos, but this is the one that earned my sub. Keep looking out for your neighbors!
Hey Nick you and your dad do some amazing nice work I enjoy watching people do extra precision love the videos
Appreciate it! 😁
My favorite thing about this video is the amount of work put into this might gave been worth more than the entire mower itself 🤣. That thing looks immaculate.
Man, it's ridiculous.. we can't fix our things! Buy new when it's broken! With everything.. I see vids from Pakistan reparing things that I would buy new! In small shops and important fixes.. we need to adresse that fixing issue...I'm a machinist since the past 5 years.. would love to fixed things .
But the head on the new mower would probably be in worse shape.
@@Dysan72 soooooo true!!
Your precision I find relaxing. Much appreciated
Aloha
Somehow this video was more fun because it was a small motor head!! Bring us more of this!!!
I’m dying over the yeet!!!
I bet that motor is going to run tiptop lol. I was thinking to myself how much the head work actually cost compared to the cost of the head when you mentioned in the video. I thought that was funny.😂
You just helped that Honda head make an extra 1hp… amazing work!
My lawnmower has a 383 stroker in it and I am also your neighbor.
It was probably like that from the factory. Your neighbor likely just gained some power lol
that is a lot of awesomeness for a little lawnmower.
I love seeing odd job types of things like this, especially when it involves surfacing heads and blocks 😊. I'd love to see more small engine stuff in the future along with the regular automotive content!
I enjoy the attention to detail on your videos. Thank you for taking the time to make your videos.
I love watching all your videos! Very soothing and satisfying
Hey! Nice Colorado shirt! Born and raised in Colorado Springs for 29 years. Just moved to Wisconsin to change it up. Good to see some Colorado represent!
literally better than new
A shop i worked in aquired an old Peterson Machine... we replaced the old stone wheel with a CARBIDE CUTTER..... Wow it worked great !
blowing 500$ in machinist hours on a 100$ engine. Thats my kind of guys! Loved this vid!
Could never be a machinist but love these videos man, keep it up!
Another great video from JAMSI!
What no port and polish?
It's not what the doctor or neighbors in this case ordered...but stage two is in the process after running in...or shud i say cutting in 😁
As always great video and narration.
wow ,very interesting!,thanks for showing the video.
ANOTHER great video bud!
I know it’s a bit outside of your wheelhouse but if you can show reassembly and start up, that would be like dessert after a nice meal.
Thank you for your knowledge and video's USA 🇺🇸
Better than new. You impress me every time.
That sure was a fun little project to watch!!
Really great video
Oh to have all that great equipment !
That is some fine work, for a lucky lawnmower!
So thats a 'Conquers' head?! :D
Ill take a seasoned, inspected, well machined, part, over a new, imported, mass produced part any day of the week. Great job. Looks like your neighbor is gonna be cutting your lawn for awhile. 😆 CHEERS!
Wish I had a machine like that also. Nice job have a good day.
That’s a nice finish surface for sure !
Hell yea!!
Small engine jobs 😎
the best running lawn mower in town!!!
The cutting inserts are round? I would think that would leave a sort of ridged surface finish. Really interesting how it doesn't, or are the ridges just so small they're not noticeable?
I liked this one! An odd ball.
What a great neighbor you are. I wish I lived next to you. ha ah
You got a subscriber from me……but let me tell you wHat!! When you flicked off the retaining clips and the YEET sound…yeah you got a lifelong subscription from me my good sir. Thank you for your hard work.
Something like this I just throw a rag under the valves and smack a socket on the back of the springs. The shock does pretty good at ejecting the keepers.
Really nice video
I had that done once on a Koehler . It had a issue with the valves making contact with the piston when it got hot.
Your neighbor thanks you.... 👍👍👍👍
Tweezers are great for taking out and putting back valve retainers.
Blown head? That's a rare occurrence.
Wish this channel had an after video update
Great job 👍🏻🇦🇺
I need a neighbor like u.
Id like to see more small engine machining. Maybe an older k-series kohler rebuild
That's a common lawn mower problem when you run high octane fuels, I learnt that the hard way
this stuff is soo cool. i have very little knowledge of what is going on, but damn this stuff is interesting.
Nice job
Way better than new!
Wow, somebody lucked out and got the right neighbor!
Another Kohler with a blown head gasket. So glad that they kohler went to five head bolts. I don't know how many I replaced under warranty with four head bolts.
Wow that was nice of you to help the neighbor like that. I'm sure a new head would have been way cheaper then doing all that work on the old head.
But this is even better then a new head.
@@firefly2472 at triple the cost if you where to charge for the work being done.
Makes great content- his neighbor got taken care of and Jim has new content that makes him money on UA-cam.
@@jasonlarsen3515 why are you telling me something I already know
@@Davidsmithisyourdad yes
I would love to see your neighbors reaction you pretty much gave him a new head
I have that same Micrometer! :)
Awesome
Do you need to get thicker head gaskets after the job to compensate for the removed material?
Compression ratio is MAYBE 8.5:1. That little amount of shave barely increases static compression. As it looks like the head gasket previously used was not a mls gasket, even torqueing the head a bit more than you should will give more CR than this shave.
TLDR: No. It's a lawn mower.
It was 0.0035 removed. That probably didnt even take it out of factory tolerances. A stock one would prob work
I see, thanks to both of you. I'm not familiar with thous and I don't have a clue of gasket thickness tolerances so eh
He put his “cleaning guy” to work 😂😂😂
I was looking forward to seeing some rewarding lawnmower footage at the end, but I was heavily disappointed. 😃 👍🏻
Man I know this video is two months old but I was bored lol that yeet had me rolling lol
Will .002" make any real difference in compression? I know old shade tree small engine builders like to deck the heads with sandpaper on a sheet of glass for a little extra power, but I don't know how much it takes to get actual gains.
That yeet got me
Haha I don’t usually do much editing like that but I thought it fit 😂
That lawn mower is ready for some boost!
I would love to see a video of how you indicate in a warped head
Have you ever done lawn mower racing engines used in go arts and such?
Your neighbor should be buying you and your Dad a nice steak dinner. Most folks I know use sand paper on plate glass to flatten the heads on their lawnmower engines, but then, they’re mostly flat head engines.
Lol my cleaning guy
I saw a valve spring removal tool on Pakistan truck repair that was pretty much just a pipe that you hit with a hammer and it works like a charm on ford triton 2v heads. I used a 17mm socket, a hammer and removed 16 valves in less than 1 minute!
Pakistan truck. Where they actually repair things and not just change parts. Those guys rock.
Very interesting, I'm working on a power washer, the customer said, it won't run, I think it has bad gas. I checked the compression , none. I pulled the head, valves look bad I'm going to.have a machine shop do a valve job next week. I'm sure this thing will run better than it ever did before. The customer may not like the cost, but if he doesn't want to pay, I can sell it I'm sure.
Very good work.
