I said it once before and I will say it again you are the best 2 cycle technician on UA-cam. You should really consider teaching at a technical school you have a lot to offer also thanks you Shannon
This is the first time I've honestly recognized the characteristic four stroking sound. It's a gravelly background sound. It's counterintuitive that plugging off a blower motor reduces load and power, but that same situation is seen in electric motors. Energy consumption in electric blower motors is reduced when you plug the output, resulting in reduced energy consumption. Higher output pressure reduces intake of static air so there's less air to accelerate, reducing load.
It doesn't make sense until you think about work being done. When the blower nozzle is blocked no air is moving so no work is being done, there is no load on the engine.
As a hobbyist of these small 2-cycle lawn care type engines, with somewhat limited knowledge of them, I did not know this. Since I have been watching some of your videos, I have purchased the Mityvac MV8500 and Spark Checkr SPC-7200. I am currently working on a Husqvarna 125E lawn edger, and I have been using both of these tools to help me get it running; an engine that I have no history of. I will have to say, I am especially fascinated by the 7200 as it works fantastically! I have to agree what others before me here having said and are saying; this channel is one of the best.
You’re too kind, thanks mate :) sounds like you’ve made some excellent decisions on recent purchases that will pay themselves off in short order and make your life much easier when diagnosing and repairing :) well done!
Thank you Shannon for the tip lol. I love this channel because it is more than just a how to but explains the how and why, I understand things like how carbs work so much better thanks ti this channel!!!
Just watched your vid on the welding issues you went through with 6061 welder in the states mate, I’m in Australia as well and have the same unimig machine as you, I’m teaching myself as well so I can make my own wheelchairs as I’m in one myself.
Hey mate! Great to see you over here :) yeah Aaron is great! I love my machine, use it every day to practise. What a wonderful idea, keep me updated with how you go, that’s incredible!!!
@@VintageEngineRepairs it was I rebuilt my Husqvarna 395xp about 3+ year's ago same carb and Chinese big bore kit, didn't even run in and it seized on 25/1 fuel, so cleaned all the alloy transfer out of original put an aftermarket piston+ rings in and it runs but likes 12500+ RPM, got an eBay cheap carb and it's the same, as saw is over 10 years young out an aftermarket carb kit in but the new needles are different, why?
Thank You Shannon and Thank You Tom. You Both played a big part in making this brilliant video happen. The both of you are very helpful and knowledgeable and pass it on to all that are wanting to learn. THANK YOU AGAIN!!!, from Wales, UK.. 🙂
Your videos have been invaluable to me as I have started going through a dozen or so pieces of machinery I have collected over the years. I've gotten six back up and running since using information you've provided. One thing I've ran across (in two machines) that I haven't found you talking about yet is fouled spark arrestors. Not sure if this is a U.S. only issue, but it's frustrating to go through all the issues and clean the carb only to find that plugged screen was the primary issue. Regardless, happy to find you and your extensive knowledge. Cheers!
Thanks for the kind words :) yes I don’t come across that very often honestly! Maybe one in 30 pieces has a plugged spark arrestor! Always good to check regardless :) thanks for watching and great to hear how much you’ve repaired!!
Great tip Shannon. I spent quite a few years on small IC engines so love the channel, but I'm sure I'll get the haters, you could also just get a battery blower and not have to worry about fuel, tuning, spark plugs, exhaust noise and pollution
Thanks for watching! Battery powered equipment produces more waste and damage to the environment than a gasoline engine ever will. The whole green agenda is nothing but a lie - have a watch of this short video that goes into the dangers and environmental impact battery power has.ua-cam.com/video/bWqPT9olQy4/v-deo.htmlsi=Un16axqQQeslnbun
@@VintageEngineRepairs Im sorry I totally disagree. The information and 100% biased (an totally incorrect information from sources backed by oil companies) about rare earth materials, how they are handled and the 'carbon' foot print batteries/EV's and electrical devices vs. the carbon footprint of IC engines especially coming from the US is total mis-information. I have been in both industries for the past 30 years (building high HP custom IC engines both diesel and Petrol/Gas) and building and racing solar race cars with custom lithium battery packs, electric motors and controllers before the rise of EV's so when I tell you it's mis-information, I have credible knowledge about the subject. The green agenda is built on politics and part of the mis-information engine and the political marketing sold to the voter backed by corporate greed
Excellent, I knew of 4 striking but not tuning the blower like that, thank you Shannon👍. Quick question, I noticed you holding the started cord out - I have heard of doing this when shutting off a chainsaw but not seen it the way I watched you doing it and wondered what you are doing there?
Glad it helped :) I just hold the rope here otherwise the starter handle gets in the way for adjusting the screws lol. But any time I turn off machines I tend to pull the rope out just through habit to protect the starter pawls in case the engine doesn’t make it past tdc on shutdown and the pawls engage. Hope this helps.
I was having trouble the other day with my chainsaw. The chain wouldn’t stop turning. I tuned the low speed to within an inch of its life but it was no good it wouldn’t idle slow enough. When I pulled the side off it I found a bit of Kevlar from my chaps wedged in there. Don’t ask and I was glad I had chaps on. Jeff
You are an incredibly awesome teacher! Your videos are so informative! I have an Echo 9010T , can the same carburetor adjustment technique be applied successfully without harm to engine? Obviously a very powerful blower. Thank you!
Yes :) same process! Blocking the tube removes the load. However with something like that, you may prefer to set it to where you think it’s right loaded, then block the tube for a second or two, listen to if it’s 4 stroking or 2 stroking and make a slight tweak then repeat again, rather than holding it against the floor the whole time
That's good to know I had a Husqvarna blower in today. Do you have any low-speed adjustment tips it won't idle right. It is pretty new I might take the carb limiters off and see what it set at. Thanks Shannon.
@@VintageEngineRepairs I don't think the customer registered the machine. Its a made in China Husqvarna Machine which i did not know was a thing. It has a HQ-2 plug in it, I don't know who make them. He should of bought it off a dealer not the cheapest place on the web.
Ahhh haha all good :) makes sense! With Chinese machines, brought online, I’d go over it with a fine tooth comb. That’s if he’s willing to pay for your time, it may be cheaper to buy new!
@VintageEngineRepairs Hmm, I already pressure and vacuum tested the engine, changed the fuel filter, tested the fuel lines, and serviced the carb a few times. The unit idles good and responds well at wot.. I just can't really set the h needle perfectly because it never richens. Are there any other possible causes? Thanks for the reply :)
Here is a problem im curious on your thoughts. I put a amazon carb on my leaf blower and it would only stay on high revs with high speed screw turned all the way in. What do you think could cause that? I ended up rebuilding the original zama and it works good now but been racking my brain as to what was happening in carb to allow that issue to only high rev w screw turned all way in
@VintageEngineRepairs Appreciate it, been bothering my brain, almost wondered if main jet wasnt sealed correctly and it was pullin fuel from past it. Thank you
I have a brand new stihl blower approx 1 hour run time in total , it seems to have a start issue any advice ( just helpful tips instead of sending it back so soon )
@@VintageEngineRepairs yes it starts , it was maybe sitting in the shed for around 2 weeks unused pulled it out and it took like 15 pulls no start , left it alone for 10-20 mins pulled it again first time it started , had it running for 20 mins , then it wouldn’t start back up again around 10 pulls on the second go
Yes :) you won’t blow it up. I made the process much more drawn out, simply because I wanted to get the audio across and clear to viewers. You’ll be able to do it in far less time. :)

Most people haven't heard of this because you aren't supposed to do it. From the Echo hand held blower owner's manual: "NOTICE To avoid engine damage due to over-revving, do not block blower pipe."

I don’t get it. You adjust the carb to “4 stroke” at no load and it will run “2 stroke” at full load. Why not adjust to “2 stroke” at full load directly?
Because you have a large window in which it can be set, often to it being either set too rich or too lean. Setting it unloaded gives you the sensitivity that you lack when the machine is loaded.
It’s a cool tip indeed but not of any use to me as I can’t find the carb on my leaf blower… I looked everywhere from behind the power cord to underneath the electric motor but seems like they forgot to put a carb in😂😂😂

Hey Tom, where is the fault at when a 2 stroke high screw doesn't richen regardless of how much it's turned out?
Hey, you’ll have to trace it right from the fuel tank through the fuel lines and then carb. Also pressure and vac test the engine :)
@VintageEngineRepairs Hmm, I already pressure and vacuum tested the engine, changed the fuel filter, tested the fuel lines, and serviced the carb a few times. The unit idles good and responds well at wot.. I just can't really set the h needle perfectly because it never richens.
