WEAK OR NO SPARK? DOES IT NEED A NEW COIL? / OLD MECHANICS TRICK TO FIX A MAGNETO IGNITION SYSTEM

[Music] what's up everybody more medicine hey welcome back to the shop if this is your first time here welcome and if you are already subscribed appreciate y'all watching all my videos today we're working on a little old garden scratcher we're working on a garden master it's a tiller plow this is a pretty old unit but as we can tell it's got a newer five horsepower engine on it uh all the controls for the choke and the throttle are on the engine and they're not mounted on the tiller any longer that spin that away for a long time i do believe the issue is we don't have any spark so we're gonna figure out why and possibly uh check and see if it's just a dirty mounting of the coil where the coil mounts could just be corroded or possibly where half we might have to replace the ignition coil so let's go ahead and i'm gonna hook up my spark tester right here and let's pull this engine through and uh let's verify that we have zero spark you're gonna be looking right here in between the gap i'm gonna pull the engine through and let's just see if it's got any spark make sure your ignition is on of course we have not go ahead and grab a couple of wrenches here i know i'm gonna need a 3 8 [Music] long and a 7 16 because there's two different size bolts holding on this blower shroud [Music] somebody i wish you look if i can zoom in on that a 7 16 and a 3 8 won't fit that bolt right there 7 16 is just too loose and a 3 8 won't even go over it and yes it says 10.9 on it so guess what somebody has jammed a metric bolt down in here so it's probably a 10 millimeter should be able to now just take the shroud and remove it and there is our ignition coil well i guarantee that would have made a vibration if it cranked up look at that dirt diaper nest made in between the fins or the fan on the flywheel my goodness what we want to do is we want to isolate this coil from the engine so we're going to remove the coil kill wire right here and then we'll retest for spark all right so let's verify that we have no spark we're going to spin the motor over with the coil disconnected and let's just check none let's go ahead and remove the coil and let's just check the mounting boss where this mounts and see if it's corroded [Music] it's pretty bad now an old school trick would be to clean up this surface here de-rust this and de-rust the engine block mount the coil back on and see if spark returns [Music] go ahead and clean up the coil both sides [Music] go ahead and set your air gap puts a little bit of pressure down on it now let's just check and see if we got spark now sometimes you do sometimes you don't a lot of the times it's just the corrosion for the coil mounts it's not getting a good ground so let's just retest look at that we got good spark now does it need a coil reattach your kill wire it's obvious this machine has been sitting so i don't know if it's going to have to have carb work or not let's see if it'll light off [Applause] got something [Applause] [Applause] [Music] so [Applause] so [Applause] so [Applause] [Applause] [Applause] [Applause] you guys just can't beat an old l head briggs i don't care what you say it's got good idle it's got good wide open throttle everything works man this thing runs good for it sitting so long [Music] all righty guys we got the little garden scratcher going one more time and that just goes to show you that it ain't always the ignition coil bad when you don't have or spark when you are lacking spark man that's the first thing i like to try to do give them a good cleaning all righty guys we got that little garden scratcher going one more time and the customer is ecstatic but anyway hey if this content helped you out and i know it did on this video give me a thumbs up and smash that like button and uh click the bell so you'll get all my new videos we all have a good rest your day and uh tomorrow's monday you all have a good week more medic one catch you on the next one [Music] you
