Hi from Australia... after taking the top off, I could see the fuel line had perished/split where it came up from the tank below and entered the carburettor. Looked in fuel tank, saw there was an excess of two or three centimetres, so figured I could pull a centimetre or so through. I'd never have figured out how to de-link the throttle linkage! . Your video helped so much, thank you! I didn't know how to get the carby out far enough to pull the split bit of fuel line off and slide the new bit over. Your excellent instructions saved me a trip to the local repair shop and a hundred bucks, or so I suspect! It took a bit longer, cos I didn't have a suitable hex screw driver, but managed slowly with an allen key. Thanks again! They are VERY good saws- have had mine through at least ten chains , two bars, and a sprocket.

Diagnosis is especially critical. Get it right and 50% of your job is done. The other 50% depends on your skill set and knowledge. Good video.

[@AllaroundNbackagain]

Glad you left all of the steps etc in there to see how it came apart. Mine is really bogging out so I need to go through it soon

[@jamesdondanville1008]

Awsome man..! thanks for taking the time to make this video... Swapping out my carb tonight.

[@williammoore5924]

Howdy, good afternoon to ya. I just received a 455 Rancher as a gift and needs some Cleaning and possibly new fuel lines. So, this Video was helpful before I attempt to Repair and or diagnose it’s issues. Good job Tks for sharing your time and knowledge.

Great Bang for your Buck Performance

appreciate the detailed video, helps alot.

[@willssmallenginerepairllc5060]

Just repaired one and they aren't too bad to work on. To diagnose a no start I have a squeeze bottle of mixed fuel that I squirt down the carb and then give the rope a pull. If it runs for a second that tells me that it has spark and compression then I will investigate the fuel system. I always pull the muffler on 2 cycle equipment to look at the piston too.

[@robertwhite853]

Why didn't you replace all the fuel lines they were all pretty old probably wouldn't it be?

[@marcduclos9789]

Thank You

[@stevenkelble5248]

good video thanks

This guy really knows his stuff I'd give him 5 stars

[@OffGridColoradoLiving]

Great video! I just liked and subscribed. Good luck on your channel growth.... These are very helpful.

[@SmallEngineDIY]

[@henryalvares7672]

first step pour small amount of mix gas in the piston and if fires up you know is fuel problem.

[@johndoe7268]

Thanks. I can do that.

[@micmichaeladflak6373]

My 460 stopped dead the other day. wouldn't restart. after removing the intake cover I could see she was wet inside the case. Spark tester was showing spark. then after pushing on the primer bulb I could see fuel seeping at the carb inlet tube and then realized my thumb was wet. primer bulb cracked also. she's 10 yrs old and I guess all the plastic lines have served their time. I have all new fuel lines, filter bulb carb kit coming from h&L $55.00 in total but hey she will be good as new. love these educational vids. thank you for your time and knowledge and sharing that knowledge with others.

[@cogentdynamics]

It would have been very helpful if you would have showed the fuel hose routing and which are ins and outs. Also your testing procedures on the primer or purge bulb. Thanks for the good video!

[@pipedreams57]

Nothing beats a good steel 5" VISE for working on saws, especially when it comes time to yank your guts out getting it started and adjusting the carb, LOL. Works great for sharpening too.

[@catpeople1958]

I actually had a vise mounted to my truck when I was selling oak firewood on the East coast. Best thing ever for sharpening. You got it! 😊

[@angelaprater2679]

Mix on gas and oil 50 to 1.on the Rancher have one. Good video thanks

[@stewartdaniels2874]

I had the same problem on my 455 rancher must be ethanol fuel I change it yesterday 👍👍

[@praetorianpatriot3267]

80% of all small engine no start issues is fuel related. The other 10% is electrical and 10% is carb adjustment.

[@scottthompson5516]

Enjoy your video's

[@SmallEngineDIY]

Thanks 👍👍

[@WilliamJones-sq8ln]

I have the same saw where fuel line dry rotted having to do basically same thing but it was, or seemed easier removing the carb disassembling the top handle/grab bar as well as the throttle handle but now re assembly was a pain as far as throttle linkage routing and back up inside throttle trigger this being my first time on the 455 rancher I could be doing it bass ackwards

[@mtsflorida]

Always put your air filter on and your bar and chain before pulling to start you don't want dust going into intake or sprocket coming off.

[@keithclark486]

Just the clutch cover will do?

[@pipedreams57]

Geeeezzzzz ! I have an older original 55 Rancher made in 2004 which has been trouble free and easy to service [stuff like the fuel lines and air filter is all that has been touched]. Looks like Husky really cheapened their 455 model and made it MUCH harder to work on. Mine did go under water one time during a flood. It ran ok when I fished it out but the coil went dead a few days later,..guess it got water saturated and shorted out. It has the original 20" bar on it and I have went through 4 or 5 chains but that is nothing. I never leave fuel or oil in a saw when I finish using it is the key to problem free service.

[@209porker]

I have a different model, a 135 but the carb arrangement is similar and showed how to remove so thanks for that. (Mine idles but won't rev so suspect fuel filter carb diaphram)

[@roymills415]

Hey Matt did you check your low needle setting, often if it won’t throttle up the low is set too rich. Should be 1.5 open from fully closed.

[@209porker]

@@roymills415 - Put a carb kit on it in the end and that fixed it and vowed to use non ethanol fuel which here in the UK plays havoc with 2 strokes that aren't used often.

[@roymills415]

Awesome !! Can’t find non ethanol here in New England, I make by own by adding water to remove the ethanol, only for engines I care about!

[@sting1111]

On my 450 I just pulled out the carb. It should not be that freakin hard to pull it out. They should have made it easier to service. I was worried I would cause an intake leak as I struggled getting it in and out but it runs fantastic after I cleaned the carb.

[@mtsflorida]

I only saw you replace one yellow fuel line and trimming black fuel line, what about the yellow long vent line?

[@hugostiglitz4777]

My 353 won’t start. Any suggestions?

[@ianritchie126]

The first thing I do with any non runner is check compression then if that’s ok put a drop of fuel straight into the cyl , if it fires you know it has spark so it’s a fuel problem , could be other problems also etc

[@mtsflorida]

Two other components he didn't mention that go with compression, fuel and spark are air from intake filter and electrical circuit or cut off switch.

[@two-strokeworkshop1154]

How do you get that sound is the muffler that makes that kind of whistle

[@cobhc1986]

Just a quick tip, on the 455 and 460, I find it easier to remove and replace the carb if I take the whole handle assembly off. Just 3 screws and the whole engine assembly can be taken out of the handle. Makes it a lot easier getting to the bottom 2 screws holding the carb on.

[@SmallEngineDIY]

I'll try that next time...

[@caldreamin09]

I replaced my carburetor it looks like that went great no leaks everything looks good seems to work but my compression super tight now. I can barely pull the cord I took the spark plug out and rotated a few times put it back still way tight any ideas you have which may help I would really appreciate. Thanks

[@philliphall5198]

These are pretty good saws and just need service

[@SmallEngineDIY]

They are pretty popular around here.

[@earltharrisjr6955]

I replaced my carburetor with a Walbo kit from Amazon. The Rancher 455 fired up on first pull. However, when i pushed the choke in the saw was still running fast and when i squeezed the throttle it would bog down like it was trying to stall. What did I get wrong on the install? Do I need to adjust the carburetor?

[@SmallEngineDIY]

Sounds like the carb needs adjusting. Running too rich and floods with the throttle. Try adjusting the air/fuel mix on the high side.

[@garychandler4296]

I have one on my bench, not starting, but trying to; air filter clogged, so that first thing in the morning: it's Miller time! You checked the coil, but didn't check the plug next. I saw a guy rebuild an engine only to find out the plug was bad, funny as hell! I always say K.I.S.$. first, LOVE later!

[@wharris7594]

broken fuel line from the primer bulb. your welcome.

[@keeganfoster1792]

Have a old husky was using it to cut wood and it was idling on the ground and it shut of fast and randomly saw was very reliable too. It turns over but once every time pulled over it kinda grabs some some but then will turn fine then grab again. Any idea or help?

[@TheKrayusKorianis]

Check the air gap between the flywheel and ignition coil. Pretty sure the gap is gone.

[@robertmoreland1220]

Primer bulb do not push fuel primer bulbs pull fuel through the carburetor and return it to the tank

[@paulserrajr4914]

Why didn't you change the gas first?

[@TheUltimate65]

Dont forget and fitted the chain..

[@michelbrown1060]

Today after taking appart my Husky 240; clean, blow it clean, carb, chain, blade and carb. . . .It would run about 10 minutes and stop. . .like it did 2 days ago with plenty of gaz in it 🤨 so iIobserved what I was cutting. . . .Then I saw the Light 🤩This small Husky 240 does not like cutting in the vertical plane. . up in my arms. . .Probably that the big fuel filter sucker is too big and it does not go th the lower side of the gaz tank. . .In horizontal, it will empty it's tank all the way 😁 Halleluya HAAAAleluya Haaaaaaleluya Haleluyaaaaaaa🤩

[@AmericanRusticWoodworks]

Decent video but you really should have pulled the spark plug out of the cylinder first and checked it even though that wasn't it that's what you do first with a chainsaw

[@roymills415]

True…Spark tells you a lot about how engine is running, if you know how to read it…

[@OseanMossfeet]

you may have found the 4th component! Compression! THANK YOU! I think the idea to remove the muffler and check cylinder itself will be my fix. :) The usual 3 are: Fuel, Spark, and ... AIR.! ;) Good airflow is also beneficial.

[@budsbustbi6339]

i have 4 of these!! bad carb is the #1 i change them out and new saw!! i have rebuilt one on self!! the new gas eats the gasquits!

Seems like every few years you have to replace all your fuel lines.

They definitely get old👍

[@buddyindigo]

lol he just pretended to tune it.

[@davebarnessr.5805]

I’d dump the old fuel before I did anything, if it’s been setting a long time!

[@gypsydrumhorse]

Mine is same model. It sucks gas too fast and sucks it right out of the fuel tank. Carburetor has been cleaned and adjusted. Bulb is good, lines are good. It won't start again when the fuel gets sucked out of the tank. It sucks the tank dry. Makes me crazy....

[@gypsydrumhorse]

filters are good and clean

[@xxResistOrServexx]

fix it yet ? sounds like same issue i have . havent done tear down yet . had it over 5 years pretty decent saw until now......

[@roymills415]

Sounds like a bad diaphragm in the carb. It’s stuck open. Ethanol in the fuel reaks havoc on the diaphragm.

I use 40:1 in all my STIHL chainsaws

[@Boost_Addict]

Google:50:1 All STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil. Knowing the proper way to mix your fuel is the first step in keeping it running strong and long. Before mixing, read your product instruction manual for additional information on fueling and fuel mixtures. Award silence .....

[@kellyronaghan5587]

@@Boost_Addict I just feel I'm being safe with the extra little bit of oil that I use. Not like its gonna hurt it

50:1 is for the EPA, it's safe to run 40:1 or 45:1 ratio. A bit more oil will help protect the engine.

Its 50 to1 lol and if you are repairing saws for others you really should have a tachometer to set the idle rpms and the running rpms, otherwise you are taking a risk letting the owner blow his saw up not realizing that you arent really a saw repair shop !!
