Chowdy Chopz: Great video. !!!!! Thanks
kenny sanchez: So I try it and it worked, awesome, thank you again this has saved me a few
hundreds in repairs.
kenny sanchez: Thank you for this video very helpful, I'm going to try this and see if it
helps my mower.
ESRepair .: Jean , Any small engines , two or four cycle, cannot run without the
magneto . You can take the charging coil off and it'll run but it won't
charge the battery . You can take the kill wire off and if it starts then
it could be the magneto . I say could be as I saw one the other day produce
spark but not enough to start the motor . It's not safe to start it like
that but it can be done , just keep all hands , fingers and tools away from
all moving parts and don't run it for long. Whizkid
steven pappas: Great video. You are the only one who mentions that rust on the mag and the
flywheel will affect spark. You also are the only one so far who gives ohm
values for testing the coil. Most people just change parts without testing
the part to be sure its bad. I don't believe in throwing parts at a problem
without knowing that the the part is definitely bad. Thanks again.
ESRepair .: Removes, I've never worked on a bike before so I imagine that their
different . Becareful . Whizkid
ESRepair .: Perumet , It's a early to mid 1990's Briggs and Stratton OHV 14 hp vertical
shaft engine . Whizkid
ESRepair .: Another way you can test the magneto is by using an ohm meter. To test the
impedance (resistance) Connect one test lead to the Spark plug wire
terminal and the other test lead to the magneto's mounting bolts (or
ground). The resistance is usually between 2,500 - 5,000 ohms. If measured
low or infinite resistance, the coil is probably bad. -MrFixit
Zukairo Domun: Hi sir,i wanted to know if it possible to use a car altenator to attach
wind blades and charge a battery.Than u very much for all your video,i"ve
learn a lot of things from your videos.Hats off sir
discolemonade66: Thanks for this! I'm dealing with it now. I was lost until I found this
ESRepair .: mcmoney86, Your welcome. Whizkid
nick896132: WD 40
ESRepair .: Thank you , MontyWard73. Saving the everyday person money was our intention
in putting up these videos . Keep on watching our videos . Whizkid
ESRepair .: oojimmyflip, True ,rust will effect the spark ,but once I clean the coils
and adjust the air gap, I have never had a problem with them after that if
kept indoors in the dry ,at least not for a long while . Whizkid
terry lumpkins: HEY WIZKID.. WANTED TO WISH YOU AND YOUR FAMILY A VERY WONDERFUL AND
BLESSED CHRISTMAS.. KEEP UP THE GREAT WORK MY FRIEND.. TERRY LUMPKINS
douglas carpenter: Who REALLY is the person with no life ? You are the one with issues.
ESRepair .: Thank you , Doug Parker. Whizkid
ESRepair .: When the air-gap is correct, Magnetos should produce near 4kV to the Spark
plug, while cranking or running the engine. You must use a special tester
to test magnetos during operation due to the High Voltage they create.
Standard volt meters can only test up to 1kV. WhizKid shows a tester in
his Checking Spark plug video. Need to spin the engine around 200 RPM to
test the magneto's voltage. -MrFixit
ESRepair .: I wouldn't be much help, since I do not work on Lawn mowers. I'd double
check the belts and linkages. It's possible something was missed or jammed.
I'll pass it on to WhizKid. He may need the model # so he can help you.
hathganus: Ho, by the way Thanks, I remeber hearing a spring go "Twang" when I removed
the old belt, but I did not see what it was. I have an ideal and will take
a look. Thanks again.
ESRepair .: gwagon2010, What she dosen't know won't hurt her . Thanks and we'll keep up
the good work. whizkid
ESRepair .: MrAlembicMan, Actually , we are just north of Tennessee, about 50 miles
from Bowling Green . Thank you for the great comment on my video. I'm very
glad that we could help you . Some say that the rust won't hurt anything
,but some say that it will . Whizkid
Livio Ciaralli: Good video. Do you know what the voltage should read at the plug cord end
off the magneto. I've just cleaned mine and was going to crank the engine
over with a drill and take a reading. By hand I can get it to 2.5 V pending
how fast I spin it.
ESRepair .: pxmstr , Thank you for the delightful comment . Glad you enjoyed the video
. K eep the good comments comming. Whizkid
rahkshi0k: I have a Briggs & Stratton. There is no spark. I already put a new ignition
coil and still no spark. The ground is okay. The air gap between the fly
wheel and ignition coil is okay. I cleaned he fly wheel magnet with sand
paper. I know whenever a fly wheel has a crack, it is ruined. Do I need to
check something else that has to do with making a spark?
ESRepair .: Some Briggs engines engines have a diode in the kill wire harness to the
coils ,that is if it's a twin cylinder with two coils , that will prevent a
coil from sparking .Check that also and make sure that the kill wire isn't
grounding out against bare metal due to a bare spot in the wire . Check and
make sure that the spark plug is properly grounded if you are using it that
way to test for spark . Buy a spark tester if needed . Try new plug ,
chance new coil could be bad. Thanks, Whizkid
cliffordelsom: Great Vid yet again explained how Magneto works going to tackle my Honda
now hope it's similar cheers once again.
stampy7777: Cheers mate great video
mikey mouse: whats the point theres no contact of the two parts, coil / flywheel ?
ESRepair .: Livio , Are you talking about the charging system or the spark plug coil (
iginition coil ) . The magneto is in the thousands and takes special
testers . Whizkid
Ken Holt: Oh wow, your engine has a govenor govennor
Doug Parker: I would bring any small engine to you for repairs. Thanks a lot, I'm having
trouble with my mower right now and I hope this will help me. Loved the
video btw, just told my wife I need a bench grinder.
ESRepair .: @Abohnher Bastard ???? I take it that to mean by the rest of your comment
that you mean it as a compliment , because I made it look so easy !!!!
ESRepair .: nojokeve, Thank you I'm glad the video was entertaining and informative to
you . Glad that we could help . Thank you, Whizkid
Abohnher: You make it look so easy you bastard!! Good video, thanks for taking the
time to put it up.
simon smith: 1) does your mum know you are pulling stuff apart in the laundry and 2) you
don't look like a whizz kid using that screwdriver at 02.50 haha Great
video , very helpful with a touch of humor , keep up the good work!
ESRepair .: WD40 or keeping it in out of the rain will help ,oojimmyflip. Whizkid
ESRepair .: Thank you , Terry . We wish you the same for a Merry Christmas . I'll keep
up the good work . Whizkid
Geoffrey Robertson: What kind of engine is that?? I think I have the same one... I need a
magneto for mine.
ESRepair .: hathganus, Yes ,I do have an idea what's wrong . You have either put the
belts on wrong ( drive belts ) or you have left a spring off of an idler
pulley or hooked the spring in the wrong place . I've seen it happen
plenty of times . Whizkid By the way where do you live ?
ESRepair .: Ken , While most of the smaller engines in use today still use the air vane
system for a govener there are some that actually use a govener like the
bigger rideing mower motors use . Whizkid
ESRepair .: Watcheruvdatube yo, Sorry ,but I don't do that stuff . That's my natural
voice . Whizkid
Removes: I shall, finding OEM parts for this thing becomes quite costly very fast
and you can only do it through auction sites. Never know if they're worth
buying or not either. If it's totally different I'll just pay my friend to
handle it for me.
William Todd: Wow, glad I ran across this video before taking my old Snapper
Chipper/Shredder to the repair shop to be charged a fortune to have them do
exactly what you just did. Gonna look at this project next weekend and see
if this fixes the no spark problem.
temarthersyt: You never said why you did this? Did you test the Magneto, or were you just
not getting any spark, even though just looking at it it needed to be
ESRepair .: Check the Spark plug gap that it's up to spec. The only thing else I can
think of, rahkshi0k, is the 'kill' wire. On Solid-State magnetos
(Electronic), there will be a small wire tab or wire (like the one in the
video) that runs from the magneto to the kill switch. It will prevent the
magneto from producing a spark if it is grounded. If it's not an electronic
magneto, check the contact points for wear. WhizKid will know if theres
anything else you can check and should be on tonight. -MrFixit
ESRepair .: These magnetos are known as Electronic Ignition. They use no points. The
air-gap between the flywheel (which contains a magnet) and the magneto
(ignition coil) must be small enough to invoke a powerful magnetic field in
the coil as the magnet passes the magneto without causing physical damage
to the flywheel or the magneto itself. Too large a gap causes a weak spark,
too small a gap and you risk damage. WhizKid's technique insures optimum
spark to the spark plug by the magneto -MrFixit
bdboatright: Extremely informative while working on my husq trimmer. However, this
should be a pg-13 video due to the gratuitous butt crack shot. Really
though, thanks for the help.
mcmoney86: Thanks Wiz Kid, this was helpful.
nojokeve: I have thoroughly enjoyed this video! It was entertaining, yet helpfully
informative. I will now go change my magneto. :-)
