I see the mowers you work on are pretty clean. Some are bad when they arrive. I finally got some out of ice to fix and sell. First off pressure wash. Makes things easier. Now time to grow horde of snowblowers for fall.
I was thinking of intermittent spark plug at first. but when you start testing the spark from the coil itself. that I had a feeling like you the coil is going bad.
I just had one where there was so much dust and debris inside the primer bulb that it clogged the fine screen under the bulb. Had been going in through the tiny hole at the end of the bulb.
How's she goin'? This was an interesting one eh!! I really couldn't detect the miss from the video, but I was impressed that you wouldn't let it go until you searched out the cause. Dogged determination!!! Nice!!! Take care!!!
Manager of Acquisitions and Dispositions, Secretary, Maker of Delicious Lunches, she is just as important to your RU-vid productions as you Bruce. Thank you to both of you!
@@BrucesShop yeah i didnt check the other even my moms mower i bought brand new carb but it doesnt spray into the filter must be a dud carberator then. ill check the toehrs too but starting it cold like that without the fluid is the issue i have with all of mine maybe this is my problem with them.
@@sonnyc3826 There are primer gaskets that are the first start. They mount behind the airfilter. www.amazon.ca/Briggs-Stratton-795629-Cleaner-Replacement/dp/B002WNVZ2A/ref=asc_df_B002WNVZ2A/?tag=googleshopc0c-20&linkCode=df0&hvadid=293001317889&hvpos=&hvnetw=g&hvrand=9863181878752391791&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9001354&hvtargid=pla-351225806070&psc=1
I bought the same identical lawnmower at Sears in 1999 but the deck rotted out after 8 years so we bought a newer one in 2007 and we sold it because we bought the new self propelled mower in 2020
Great detective work, Bruce !! Starts like it's brand new again. Have you ever tried a short length of 3/8" fuel hose to remove loose spark plugs with? It's a perfect fit over the insulator porcelain. It's also great to reinstall plugs with too !! Use your ratchet and socket to break them loose and final tighten them. You can also use longer lengths to reach plugs in restricted areas with no worries about dropping the plugs either while removing or replacing them. : ) Works a charm. Have a great week !
@@BrucesShop More than once I've heard you say how hot the spark plug was in your hand...just trying to save you from a little discomfort. : ) Happy Holidays to you and the Mrs., Bruce !!
Nice work Bruce. I have a briggs like that one on a leaf vacuum the are pretty good engines mine gets a smell like something is burning when it gets hot I have taken the cowl and everything off but can't find nothing wrong and it runs like a top. LOL
Very cool. The master at work. Snow blowers probably coming soon for you guys up north. Dave A already has his heat shield up in his shop to keep warm while working. Stay well and see you on the next one.
I bought a Braun brand swivel light at Harbor Freight couple years ago, love it. And the magnet is a neodymium type, and it does NOT detach itself from the light.
I suspected ignition from the start because the primer was working, he sprayed, and it was starting in a flooded condition you could tell. Even if the carb was completely plugged it still should have ran for a second which it did not. I have always disagreed with Bruce’s philosophy on spark plugs too! They are cheap easy to install and most repair places automatically include one in their tuneups. It would have made it more obvious that the coil was bad as well. Anyways good job finally having a spare coil for testing although I would never install a used one in the customers machine unless they specifically agreed. I would not want the used one on my equipment because it’s likely as old or older then the one I had. Age and moisture combined with freezing temperatures are the greatest enemy of coils. In the winter ever notice how equipment owners with heated storage have fewer breakdowns? If you run a plow truck the difference is radical!
@@BrucesShop When it comes to spark plugs I don’t think the number of hours on it have that great of an effect on whether they’re good or bad. Obviously if they’re ancient they’re gonna go bad at some point, but most of the ones I have proved out defective are not that old and they look just fine. Now they may test out with a multi meter as bad but looks will get you nowhere(looks may tell you about other engine issues though). I’ve had spark plugs test out just fine on a multi meter but the engine still wouldn’t run right or would run goofy until I replaced it with a new one, your mileage may vary. Most companies consider the price of a spark plug a good investment to prevent call backs and promote customer satisfaction.
I thought more pulls just came with age naturally....like attempts to get out of bed in the morning. I would only get concerned if my mower didn't start after the 21st pull.
Both Briggs and Champion recommend 5w30 synthetic for all temperatures, so multi grade is fine by them. My Briggs is a snowblower, and Champion a generator. I buy what ever 5w30 synthetic is cheapest and on sale and use it on both. I also put it in an old Tecumseh mower with no issues.
so im curious did he keept eh card in there? this could very well be the problem wiht all my mowers shows i dont know everything about them yet..ive been doing pretty good from elarnign from youtube..they all workd but again dont start first pull cold. sprayed wiht carb cleaner into filter they do...maybe ill try this card trick
You basically have covered all the bases in this one my friend. The only additional thing we will do on a full tuneup is check the torque on the head bolts (normally find 3 on the muffler side loose from heat, expansion and shrinkage when cooling) then we mark all with a paint stick. If it is OHV we will torque those also again we normally find them slightly loose. Looking forward to the next one, the OLD MAN at EP over and out!
Another great video. Well diagnosed. You certainly know your small engines. That mower looks to be in very good condition. What does that metal piece in the air filter box actually do?. Bruce I have a Ryobi petrol leaf blower /vac. It starts OK from cold, but is hard to start when hot. I have to wait for it to cool down, any ideas. If I lived in Canada I would drop it round. Thank you.
I think (just me now) than metal piece does 2 things. It stops gas spray from the primer from getting on the air filter and guides crankcase gases up to be burned.
As a rule of thumb, I get a mower in that I don't know, I do this.... On briggs quantums 1. Carb ultrasonic cleaning, new gasket, new air filter. 2. Check for sheared flywheel key, I don't even bother pulling the rope till my check list is finished. 3. Tighten intake bolts. 4. Tighten head bolts, they always need a 1/4 turn. 5. Sharpen and balance blade. 6. Gap coil 7. Check, and or replace spark plug. 8. Drain fuel. 9. Change oil. 10. And last but not least, lube, and clean mower. I do all those things as a rule of thumb.
