Definitely going to try this got a K321 engine and some other engines that need bored out would like to do it my self cause shops charge too much and cant find one in my area. Thanks for the video very informative!
Very informative, and seeing it done makes it not as scary as it sounds. Thanks for sharing. Maybe you might consider building a jig, perhaps using an old pillar drill or some such so you can bore vertically - that would make a great video? Would gravity - seeing as it was being bored horizontally - make any difference to keeping it round, that is would the weight of the cutter bearing down on the bore take more off the bottom than the top? Hope the question is clear. :)
Yeah, i understand that, i was afraid to do it on the first engine. Your welcome, your probably right, vertical would be best too i think, but i don't know if it would be enough to make a huge difference. Yes it is clear, I honestly don't know if it would make that big of a difference because of how this type of hone works, putting pressure out instead of being spring loaded. Thanks for Watching!!!
if ppl check/add/change the oil every 20 hours and change /clean air filter every 20 or so hours... motor wud last a good long time. i got one. the bolt fell out of the air cleaner... so instead of finding a bolt or going to HD and buying a bolt... they used tape to sort of hold the air cleaner cover on. motor had deep grooves on once side of cyl like that one. i honed it some with cyl hone, same piston, new rings, cleaned it up/painted it. will run 20-50 oil with 20% STP oil treatment to make oil thick as honey and run it with NEW AIR FILTER (5 for $9 on e bay) and NEW 25 cent 1/4" x 2" long bolt from HD to hold the air cleaner cover on. wont last forever but it will last long enuf for me in the re purpose i have planned for it. something to do, take apart, clean, new rings... for 190cc engine... not even briggs engine $9 rings vs $30 briggs rings... we will seee how the $9 rings hold up. im sure it will be fine.. with OIL IN THE MOTOR and not leaking out the bottom of dryed out seal that was worn out from lack of oil (sigh) .
Nice Job. Have you seen the video of the guy in Finland (I think) who made a V8 engine out of the flathead B&S engines? It is pretty amazing what he accomplished. Just do a search in the RUclips search bar for "Briggs & Stratton V8".
Did you ever use that hone on a outboard cylinder? I would like to bore out a 2 hp Johnson outboard cylinder .030 but that hone cost over $250.00 on Amazon.
this happened with me alot , looks can be deceiving at first i though i could hone it out with like say .010 or .020 (i would not go past that ) .......nope not even half the times ... specially if im doing it on an old V8 hone first then decide if you can buy a piston that matches the current size or just scrap it
allways figured they used a hard chroming of the cilinderwall and use cast iron piston rings to reduce wear , on cast iron bushes the would use the chrome pistonrings
I think it would be better to take it to a machine shop since that hone costs $160 dollars you only have one hole to bore and hone and I don't think the machine shop would charge that much so you could probably pay to have this done a couple of times before you would benefit from owning that tool the machine shops can afford to buy the stones and hones and boring machines because they get enough work in to annuitize their cost out over time. Not that having that tool is a bad idea just not sure for a one cylinder engine it is worth the initial outlay if you are not planning on doing multiple engines
When i was working in the machine shop we had a power hone with a sunnen head and if a 2 stroke came in with a .25mm osize piston i used to just hone it out you actually got a better clean up as 2 strokes tend to wear around the ports and sometimes boring them first they wont clean up as well as if you just hone them.
it'll be fine. if ppl wud change the oil every < 25 hours. put a new air filter on it once a year. clean it every oil change. it will last a long time... but ppl cant even check / add oil to the motor. i paint the motor and write on it with paint pen CHECK THE OIL BEFORE EACH RUN OF THE DAY!!!!! even have stickers on E bay if want to do it that way as apparently ppl just cannot check the oil before first run of the day... or have oil on hand to add oil to the motor when it is low. if it is worn some... more than we like... run 20-50 oil with 20% stp oil treatment to thicken the oil up some. oil turns to water when it is 100* in summer anyway and realize it is a mower engine, prolly wont last 20 years... unless... check/change the oil once a year and dont put that many hours on the machine a year as grass doesnt grow that much in some places ... in the west without constant irrigation 3x/week.
I had a Tecumseh iron bore 3.5hp mower last 17 years. Went through 3 sets of wheels and many blades. I got it off the curb for free when it was 2 years old, cleaned the carb and air filter, changed the oil and sharpened the blade. My Honda mower is 5 years old and runs like new, that one will be around for 20+ years. Take care of your equipment folks!
Yep, still using the same 3.5HP B&S push mower my dad bought new in 1977. Always checked oil before each use, changed oil twice a year, cleaned cooling fins and air filter every so often. It's still the best running mower on the block and runs just like it always has. Still has the factory crosshatching in the bore also when I stick my bore scope in the sparkplug hole. That thing has about 1500 hours of use on it and it's hit some stuff that should have killed it long ago. In 2004 there was a big chunk of underground electrical wire thrown into the back yard when we were having a lot of house work done. I hit that thing at full throttle one week and it stopped that engine dead in its tracks so fast, it fired right back up like nothing ever happened. To make it worse, my dad did exactly the same thing I did with it the next week. That thing went from 3600 RPM to zero RPM instantly both times.
@@Taz669 You are supposed to measure the piston, then set that dimension into your dial bore gauge. Then you hone to the proper clearance. The way he did it he has no idea what he has for piston clearance .
I bored a motorcycle cylinder with a Lisle 15000. It was at 1.5 mm over already and I took it out to 2.00mm.
Took a while but it worked
Cool vid. I only have the 3 stone type hone, I guess that explains why it took me Forever to hone a 4 horse Briggs .010" . Great vid!
That hone looks to be the ticket here. I learned something new watching this video. Thank you for sharing!
Wow! that cylinder cleaned up nice!
I think that's going to work out just fine, I guess we will find out when you fire it up.
Nice work Bud👍
I think so too, it seemed like all the specs were right there, hopefully it holds up. Thanks for Watching!!!

Did it go to 3in? The one I'm trying to do is 2.91xxxx and I need to go about 40 over. Does this fix out of round?

how long did it take u to hone it up
Who has b/s over size pistons besides b/s ??
Any aftermarket places ???

New 5hp engine don’t even cost that much. What kind of black hole are you creating
would this work for 2 strokes?

My friend, and all my friend, a 1/2 inch Dewalt will break your wrist!
This is cringe
A lot of information to absorb for ya buddy? Why not watch it a few times it will catch for you eventually.
