If you only run synthetic 50:1 premix canned fuel it eliminates most of these problems. I prefer and use both the Stihl MotoMix and Echo Red Armor. Either that or find ethanol free premium 93 octane pump gas for your own mix. The ethanol in modern pump gas is the culprit for most of these small 2-stroke lawn and garden equipment failures. I have 3 chainsaws......Stihl MS-391, Echo CS-490 and this Husqvarna 435 X-Torq. I learned a trick to get these started because they don't start like the Stihl or Echo and never has even when it was brand new. If mine doesn't go following the instructions on the sticker exactly I have Plan (B) that almost always works. Wedge your boot/shoe in the handle and pull up the throttle lever with your foot. Hold it wide open full throttle with the chain brake off and also the choke off. Make sure you are on solid ground and your bar/chain is pointed in a safe direction away from anything you don't want to cut or damage. Now pull on the starter rope. It will usually go after a few pulls while doing that. I will say my spark plug was ridiculously over tightened from the factory when new just like yours. After I broke it free to measure the gap with a feeler gauge to make sure it was 0.020", I put Permatex 80078 anti-seize on the threads lightly. I only tightened it up as the same tightness as any other small gas engine. It doesn't have to be as tight as they make it at the factory and will lead to problems later if you don't loosen it and re-torque it to a reasonable firm hand-tight.
Also learned another trick with this Husky I just remembered. Before you shut it off let it idle for :30 seconds to 1:00 minute before hitting the kill switch. I believe it stabilizes and preps the carburetor for the next start. Every time I have done this my Husky always starts up on a few pulls. I think the reason these saws get such a bad reputation is because owners don't take the time to learn and overcome their little quirks.
Great video. I know how much effort is required to create and share videos, so that's just you so much. If anyone needs to know how to Clean the carburettor, there are other videos with more details.
@@michaelwerger3722 yes it does, idk why I didn't show that on the video. Without doing that cleaning a carb is a waste of time. Any debris will get pushed against the screws and put back in the carb all over again. Very important step!
Nice video. Thanks a lot! You mentioned to keep the sequence of lines for the kill switch. This is not required as the lines just need connection to kill the engine. So you can connect either way.
I owe you a beer. Took me an hour to get this beeetccch out, lol. Tell you the truth, although I like my Husky's (they start dependably) compared to my Stihl's I'm less impressed. I have a 435e and a Rancher 460 - and both are harder to take apart then my Stihl 250 and ancient 026. Plus the Husq's have a couple of plastic parts that can break - I've never broken anything internally on a Stihl.
You didn't clean out the bottom half of your throttle body, there is a screen there that filters the gas before it comes thru where the needle valve is...
I know! 🤣 I did do it off camera, but failed to mentioned it in the video. Someone else mentioned that too. My mistake! I appreciate you pointing it out!
It's been run quite a bit. Owed by a contractor and all his machines are spottles! Even his plate compactors are clean. This saw was at a different shop for almost a year and still wasn't running properly for him and they charged him over $200!
The best thing to do is to slowly turn in the Welsh screws and count the turns. Where it was set from factory should be best, sometimes open them slightly. Turn in until lightly seated, then remove them. When its back on the machine, the only other thing you want to check and adjust is your idle. You can slowly adjust the Welsh plug screws if needed in very small increments to smooth it out.
As a bit of a baseline starting point factory it comes 1.5 for high and 2.5 turns out for low. I had to adjust mine quite a bit because whoever tried to fix it initially had it maxed out and this got it so the saw would start up again and was really close to what ended up being the best adjustment after I got everythibg bsck in order. Good luck. Thanks for the video they are appreciated.
Hey man I tried all this and it runs for like a second at full throttle anything you recommend to try or just replace it i even tried boiling it in lemon juice lol
