    Thanks so much! My generator wouldn't start. Old/bad/ethanol. Took carb apart and cleaned and found main jet 100% clogged. Broke clogged w/a a sewing needle, then soaked all parts in a detergent followed by a gasoline bath and reassemble. Started first pull. But engine surged/hunted in idle. Removed pilot jet and used your wire brush technique and cleared the main passage and surging cleared up! Thanks to your video, my home had power in the next ice storm. Keep producing videos!

    Your presentations are organized, clear concise and … well, perfect. You speak clearly, and with authority. You use proper grammar and at a perfect cadence. Those are qualities some people take classes for and most never achieve. From the beginning of the video you state what you are going to cover and start right in. And you actually cover it. On a one to 10 scale, I’d give you a flat 15. You are really good.

    My lawn mower was ;surging / hunting so I went on line for that symptom,for that type of mower and they said to be sure the vent holes, in the gas cap weren't clogged.
    I blew air in the holes in the gas cap, and it WORKED! The engine leveled right out to a steady speed, problem solved!
    The gas tank was drawing a vacuum because the vent hole were plugged and engine was starving for fuel. Easy fix and worth a try!

The surging stopped, but now the engine pops, like a back firing of a car. Any suggestions? This is an LCT engine, can I get a new idle jet for it? If so, please send a link where I can purchase one.

  • @davidm7824
    @davidm7824 2 роки тому +6

    One thing I found out about adjusting the carb on my snowblower is do not adjust it when it is warm outside. I adjusted mine when it was 70 degrees outside. When I went to use it for the first snowfall, it was running very lean and had to richen it up a lot because it was colder outside. Meaning the air was denser and needed more fuel. lesson learned.

    Outstanding description.
    I just sold a craftsman blower than started on the first pull for 13 years every time. Changed the oil every other year and gave it more premium gas when needed. Never any stabil or anything. That brings engine was amazing, but the machine seemed to be struggling to move the heavier snow.
    Just bought an ariens 10hp ax engine blower - looks great, but it took about 10 pulls to start at pickup. The guy said it had never been started, which I thought was weird since they had put fuel in it.
    So my question is; what can be done about cold starting?

    Great tutorial! I've got an ancient hand-me-down Simplicity 860E with a mystery horsepower Techumseh. I just replaced the carb today and both fuel/air screws were all the way in and bottomed out. No big deal armed with your tutorial though!
    I've been in mechanical services of one type or another my entire life (I'm 64 1/2...when did THAT happen?!) but adjusting both screws is definitely an art. I found a balance I can live with tho. I was having an issue with not having the main jet adjusted to the sweet spot and went I went from idle to full throttle it just went bauuuuugghhhh until I moved the throttle lever back down toward idle. Watched the adjustment part of your video again, started from square one, and I'm happy with the results. There's an occasional pop from the exhaust at all speed ranges (spark plug got replaced too btw) but not horrible.
    It's 75 degrees out today here in SE Wisconsin so the true test will be when our winter temps slam down below zero.

    I've learned so much from your videos. I'm getting my blower that I picked up last December as a project,
    (craftsman 9/28, techumseh model LH3185A) ready for the winter and it would only run for 2 minutes before shutting down. Didn't have a inline filter and found some @rap in the bowl so took it apart and used a ultrasonic cleaner, welding touch tip cleaners, air compressor and that solved the problem and it runs great and added a filter but I
    am experiencing a "miss" at high speed. Runs great at lower speed, and the popping or missing doesn't slow the engine down. Should I pull the cover and check the condition of the flywheel and coil for corrosion? Thanks, Mike

  • @jaysantos514
    @jaysantos514 3 роки тому +6

    Thank you for this wonderful video. I was always under the impression that the new engine actually increases its efficiency when the rings and cylinders conform increasing suction of air and therefore metered fuel is insufficient. I thought by drilling the holes out you were increasing fuel to match the increased air intake.

    • @EliminatorPerformance
      @EliminatorPerformance  3 роки тому +5

      Those pilot jets meter fuel during idle, so enlarging them gives more fuel, because of slightly less compression so it's harder to pull more fuel through. You're basically making it easier to get fuel. Once you get into snow, auger turning, engine under load, it pulls more fuel easily through the larger main jet.

    I have a non adjustable carb and the kit I bought included the washer and o-ring for the adjustable idle mixture screw. After refurbishing the carb, the engine was hunting so I converted the fixed screw into an adjustable one by finding a suitable spring and using the other parts. So even with the predrilled screw, I was able to adjust the mixture and smooth out the engine and get a good idle.

    Thanks for the video. Looks like this carb was adjusted at zero choke on a relatively warm day. If I need to do this in the cold, should I wait for the engine to warm up? Or can I adjust the needles at a higher choke setting?

    • @EliminatorPerformance

      Wait for the engine to warm up, you may find if adjusting in warmer weather, that you'll need to increase a bit of fuel on the main once the colder weather comes. So maybe 1/8th turn out.

    Great video, brother! Thanks!
    I have a Tecumseh HMSK100 that originally had a jet bowl with adjustment. The bowl was replaced at one time with a bow without adjustment.
    The engine does surge. As a first step, should the bowl be replaced with the original adjustable type?

    Great explanation my fellow Canuck! Well done.
    I am resurrecting an old snowblower that has sat for many many many years in storage to have ready for my daughter next winter. I drained old fuel and used premium fuel, cleaned the carb passages and still have hunting issues. Note that the governor pivot point was stiff from rust but have freed it up so that it moves again.
    I have the carb style you showed that has an adjustable main and an air screw.
    When the engine was warm and at high throttle, I opened the main to try and get rid of the hunting but would not go away and eventually it started to flood. At this point the main was open a large amount at 3-4 turns and took a 1-2 turns back closed to clear up.
    I’m thinking I still have an issue with the carb internals or the governor.

    Thanks for sharing, one thing that is worth mentioning is as an engine breaks in the seal between the piston ring and cylinder actually improves and the compression rises. Either way, great video and info on drilling fixed jets :)

    • @EliminatorPerformance
      @EliminatorPerformance  Рік тому

      Yes I'd have to agree, as the piston rings seat they *should* seal better. The issue is, these engines pull less fuel through once broken in. So the question now is, why? It's either the cylinders being a bit out of round or the rings not sealing as good, or it's the valves not sealing as good. This could be tested by doing a leak down test and checking blow by into the crankcase or intake/exhaust ports. Somewhere, compression must be decreasing for the engine to pull slightly less fuel through.

      @@EliminatorPerformance Do you think it could be related to temperature, weather, humidity changing since being tuned from new? Some carbs and engines are quite picky to changes in temp and humidity!

      @@VintageEngineRepairs no because customers say the same thing, they ran fine at the dealership when they fired them up, or for the 1st week, and then all of a sudden they surge. Oversizing the pilot on the new MTD engines is something I do to all the carbs now to prevent this. Usually going from the factory 0.016" size to 0.018" is all it takes. Although sometimes it requires 0.020" for the larger engines

      @@EliminatorPerformance As the piston rings get seated and the unit pulls more air through, the fuel to air ratio decreases. More fuel is required to to keep the ratio the same. That is why the screw needs to be slightly opened. (I think).

    Good job. One of the better carb diagnostic/adjustment vids on YT. Few things to add...
    1) nice job explaining carb schematics and what jets/adj. do what. One thing to add before the drill bits come out, make sure intakes don’t have any air leaks and air filters (if equipped) are in place and clean...snowblowers not so much of a concern.
    2) fuel preservation only happens if stored in a sealed plastic gas can or tank. It will not stay preserved in the carb bowls.Tyrall has finally come around to my understanding and knowledge with his fuel stabilizer test.
    Subscribing and will be catching up in your other vids. Keep up the good work! There ain’t many of us left that know this stuff anymore!!
