When I was doing small engine repair, I'd clean them up. Customer always appreciated that.

[@TheLawnmowerLady]

Right on Mr Bert! I clean them up too, to keep me from getting so filthy.

[@henrymurawskibigdogrepair]

Yes clean machine will keep them coming back

[@BrucesShop]

Great Job. I must confess I don't torque the top nut. Just tight for me. Very nice work.

We subscribed! We've already watched 4 videos that aren't specifically about our Honda mower, but your explanations are so clear and well-presented that they're enjoyable to watch regardless. We own a Honda HRN216VKA lawn mower that suddenly stopped working about 3 months ago after its last use. We usually hire someone to take care of our lawn, so we don't use it often. We've already changed the oil, replaced the fuel, replaced the spark plug, and cleaned the air filter (which was barely dirty). We also checked the carburetor, and it appears very clean with no signs of water or dirt. Unfortunately, the mower still won't start. At this point, can you please recommend the next troubleshooting steps we should take? We'd also appreciate it if you could suggest the tools and any lubricants we might need to get this mower running again. By the way, here's a tip we learned while changing the oil: Even after the oil seems to have stopped draining, tilting and flipping the mower a few times can help get out even more oil! Thanks. Looking forward for your response

[@kbssmallenginerepair2615]

Great video. It’s always satisfying pulling that flywheel nut at seeing the sheared key.

[@TheLawnmowerLady]

You're right Mr Kyle! In a strange way it is.

[@barrynamendorf7549]

I have watched a couple of your video's it is a pleasure watch you work. I have bin rescuing curb side small engines for 35 years. It is A real pleasure to watch you teach how to do things correctly.

[@TheLawnmowerLady]

Thank you very much Mr Barry! I really appreciate you watching. Hope you stick around. 😀

[@jeffreysabo5285]

I just went through the installation of the Carb rebuild kit for the exact Briggs and Stratton motor and Carb. setup that I have. Nobody else ever mentioned this exact Mower setup. I am still trying to keep it running after a col or warm start. It seems that I might have a Fuel Flow starvation problem possibly. That or one of those little ports in the Carb body itself may have slipped by me without being clean out. I guess that we'll see when I do this removal of the Carb once again. Thank you sincerely for a excellent job of presenting a very clear 😅How-to-walk-through. Jeff Sabo (Edge)

Very good camera work Stella! I hate when the engine jerks the handle out of my hand. Your repair was spot on and your step by step of the repair was excellent. I love to see people using a torque wrench in stead of just putting the jack hammer to it! ✌🇺🇸👍 Roger

[@TheLawnmowerLady]

Thanks for watching Mr. Roger. I figure a job worth doing is worth doing right :) I'll wail on my own stuff, but try and go by the book on other folks equipment. Cheers!

[@dfields9511]

Great explanation , I typically pull the fw with hammer and brybar. But using a puller is the right way to do it

[@TheLawnmowerLady]

That’s a good way too Mr. D. Sometimes I have trouble banging it off with a key so badly smeared on the taper. I’ve bent smaller cranks when they really stuck on.

[@andersforrad]

@@TheLawnmowerLady Agree with you. Strangely when the key is sheared, the flywheel is often stuck soooo much harder on there.

[@TheLawnmowerLady]

Thanks Mr Hank for watching!

[@nielso.kristensen8056]

Good video. Another violent recoil kickback reason can be a loose blade because it was´nt tigthened enough to the blade adapter or a friction disk was worn out. I have experienced that after destroing to drills using them on flywheel attempting to start.

[@TheLawnmowerLady]

Another thing I've noticed too, is flywheels rotated only a few degrees out of spec, the more violent the kickback. I've had my fair share of bumps, bruises, and twisted wrists using a drill to start these small engines :) Thanks for watching Mr. Niels!

[@CortinasAndClassics]

Hi Stella, thank you for the video. Very clear indeed, I will need to get a tap kit and a puller but they are not too expensive.

[@TheLawnmowerLady]

I'm happy to help. Some folks put a big prybar under the flywheel and whack the end of the crank with a big hammer. I'm not too keen on that method, easy to bugger the threads of the crank, and can damage the flywheel if you pry up in a weak spot. Cheers!

[@spagsketti]

an air hammer will yard it off quick as well. little pressure under the flywheel and hit the air hammer on the shaft it will pop up no prob. Using them pullers are a pain in the rear. So much easier to just use an air tool to do the work.

[@TheLawnmowerLady]

I agree, but I tend to gear my videos towards the DIY homeowner, who often don’t have tools like that. Thanks for watching.

[@BADD400]

[@TheLawnmowerLady]

You are welcome Mr Matt! Thanks for watching.

[@waynestefinashen239]

Buzz the OLD MAN here from Eliminator Performance: Good thing you did not snap an elbow cause that is how bad the kick back can be. Very good video, we normally just whack the crankshaft with the nut flush and light pressure with a prey bar under the flywheel and they pop right off. Woodruff keys are half moon shaped and made of steel normally on riding mowers, the push mowers normally have aluminium keys of different shapes ie: B&S straight rectangular and Techumseh has an offset key in some cases. Taryl normally uses an air impact hammer if the crankshaft has the countersunk center.

[@TheLawnmowerLady]

Ha! I cringed when I heard myself say woodruff and knew I was gonna get busted :) In my defense, I come from the moped and antique scooter world and they're all woodruff keys, not sacrificial like these small engines. Thanks for watching Mr Wayne!

[@KensSmallEngineRepair]

Eliminatot beat me to it! Just like when people call keys key-ways! Drives me nuts!!! Good Vid Stella!

[@TheLawnmowerLady]

Yep! That too. I say "atomizer" all the time rather than "emulsion tube" for the same reason. Reminds me of that riddle: Why do we park in a driveway, but drive on a parkway?

[@waynestefinashen239]

Never worry about getting busted just about every KZbin creator has bloopers that they either have edited out or just left them in to see if someone comments on it. Keep up the good work, glad to see the ladies getting involved.

This kickback was minor in comparison to others that are only a few deg off. One nearly popped my shoulder out of the socket. I was sore for days. :(

[@ronniebarker79]

Will have to get some courage from the lion ill pull it again when im pissed off

[@rickthelian2215]

Did you replace the blade or repair it dumb question…. Loved this video😀

[@TheLawnmowerLady]

Thanks for watching Mr Rick! That guy got a new blade for sure, and if I recall, maybe a new blade adapter too. I'll sharpen a blade but I won't bend them back into shape.

[@philliphall5198]

I look at the blade first to see damage, if so pull flywheel 95% of the time it’s fuel related such as carb

[@TheLawnmowerLady]

I agree on the 95% fuel issues. Thanks for watching.

[@420gzuz]

craftsman tiller encountered a big old rusty smashed and buried section of galvanized culvert under my blackberry field. couldn't use my hand for weeks after. so painful!

and this was after i replaced the pull cord 3 weeks after purchase when it snapped in half on recoil!

to clarify, hit the culvert section first, ripped the pull cord second, hurt my hand third, about to replace the key next

I'm having the same problem. I asked eliminator performance wayne and Jake they said same thing.. well the sheerkey is lined right up. So now I'm stumped

[@TheLawnmowerLady]

Have you pulled the flywheel to inspect the keyway? I've seen them run poorly and kickback with just a few mm of twist. Thanks for watching!

[@philliphall5198]

Check valve lash next

[@joeortiz3455]

That was a good lesson , curious question was there a need to set or recheck the coil? Or did the fly just spin Free and not get its position disrupted?

[@TheLawnmowerLady]

Thanks for watching Mr Joe. I usually only need to re-set the ignition gap when I move the coil itself. Never had a problem with the gap after removing a flywheel.

[@joeortiz3455]

HI My lawn mover brand new Brigg&stratton EX 675 ,when stop engines few second it make noise ,and show me RPM How much Thanks

[@jeffreyk5933]

Not to be pickey, but the arm from the thermal actuator is bent against the choke air vane. This hinders the free moovement of the air vane and will cause the engine to run too rich. I think that strong observation skills is one of the most important parts of being a good service tech. A little side note, A "woodruf key" has the shape of a half moon, otherwise any other shaft key is called by it's end profile.

[@TheLawnmowerLady]

I addressed some of your concerns in earlier comments. Thanks for watching.

[@Animalfarm4481]

I got mine apart and looks fine-could the brake be causing it to kick back? It looks like it is disconnected and rubbing on the flywheel magnet

[@TheLawnmowerLady]

Absolutely if the cable is indeed broken. Do you see the brake pad move when you activate the cable? I made this video kzbin.info/www/bejne/bmmXpKSvfqqDbcU More of a generic how-to rather than a model specific, but hope that helps.

I have had several Briggs and Stratton engines on old mowers when been stood a long time clean carburettor run perfect then go back later and won’t start kick back on pull start checked timing oil level valves can’t find a problem is it oil getting passed rings any thoughts as have had a few like this please

[@TheLawnmowerLady]

Next time that happens, pull the spark plug, pull on the starter a few times, and replace the plug. If it starts fine then, you are getting partial hydro-lock either from oil or fuel getting to the combustion chamber. Replace the needle seat in the carb to eliminate fuel fuel getting in there. And store the machine with the pull cord just where it gets tension to ensure both valves are closed. That’s my guess?

[@kennethwood1850]

Many thanks will try the pull cord stored under tension

[@RattyFlyer]

How often do you come across the failed spark plug coils?

[@TheLawnmowerLady]

not as often on lawnmowers as I see on 2-stroke tools.

[@garrycoleman2494]

Maybe you can help me I git a black max 450e push mower my flywheel key was sheard so I fixed but still won't start so I put a new carburetor on it still won't start so when u go to pull the cord it pops and a little flame come out of the carburetor any suggestions on what I can do next

[@TheLawnmowerLady]

The next place I would look would be under the valve cover. Confirm the valves are indeed opening and closing. These mowers have plastic cams that can spin on the camshaft, and create a similar timing issue. I hope this helps.
