I like this guy, no nonsense but all the information you need, I get tired of guys showing you how they unscrew a bolt!

[@chainsawace1777]

Thank you for the nice comment and the view. Have a great day.

[@boltsowner35hhhd]

Love the up close shots. Best comprehensive video i've seen on KZbin about Husqvarna

[@chainsawace1777]

Wow. Thanks so much. We're just getting started with this whole KZbin thing. We have lots of cool things planned, like rebuilds and restorations, along with how to repair videos. We hope you stick around to see them.

[@carlbeckford-uf6yx]

Very good video

[@chainsawace1777]

Thanks for the visit. Really appreciate you.

[@Stihl-Alive044-nc8op]

I enjoy your videos.

[@chainsawace1777]

Wow. I really appeciate that. Stick around we have some cool things planned.

What cleaner are you using sonic cleaner

[@Joe_Blo]

Got a video on how to install an antigravity unit on a 455? I like mine. It's like a Cummins Diesel in the wood. But I'm getting old. It's heavy and hurts my neck & back & elbow & knees. Wahhh! -Pro saws are good for around 2000 hours. A 455 is likely good for close to that (except the fuel system) due to metal reinforced crank case and large crank bearings, if it's taken care of. But even if it only lasts half as long as a pro saw, it's only running for about an hour per cord. If you cut and burn 10 cords a year, it'll last 100 years. If only 5 cords, 200 years. If only 2 cords, you bought the wrong saw. They're a good used saw to buy too. You might get lucky & find a well cared for one from an old codgers estate who died from a stroke or snapped his back in two all alone in the woods while heaving his fat toad firewood saw around and was eaten by wolves or coyotes. If so, buy it. Bonus: After one season cutting firewood, you'll be built like a brick outhouse from the workout you'll get. It you'll need lumbar surgery.

[@chainsawace1777]

Great comment! I love the Husqvarna 455 as well! Thanks so much for watching and taking the time to comment!

[@mikeobenland4395]

I know you made this a couple years ago but thank you! Quick question, when adjusting the carb do you need a special tool?

[@chainsawace1777]

It depends on the chainsaw. Some older saws just required a small screwdriver. However, newer chainsaws require a special tool, but different brand saws use different tools. Here is a tool kit that has about everything you need for adjusting carbs. HIPA makes this one. Very good quality: amzn.to/3woopbF

[@qwerty90615]

Very good video. What solution is used in your ultrasonic cleaner?

[@chainsawace1777]

I use LA's Totally Awesome All Purpose Cleaner. It works great and does not discolor the carburetor. Thanks for watching. Really appreciate it.

[@leehenry6397]

How do you get the primer pu mp out

[@chainsawace1777]

It clips in. Press each side of the clip, from the back side of the primer and it will come right out. Thanks for watching!

[@chainsawace1777]

Thanks so much!

[@gunterbecker8528]

Sir,how do I remedy the black substances on my sthil saw muffler? Its a fairly new saw as well ! I'm running 98 octane gas with a 40:1 mixture,using sthil oil ! Thank you in advance Gunter

[@chainsawace1777]

Hi, thanks for watching the video. Your problem is you're running the wrong fuel mixture for a STIHL. All STIHL Chainsaws and other gas burning handhelds run a 50:1 fuel mixture ratio. You are doing the correct thing in running a high octane fuel. The higher the octane the less pre-detonation of gas in the cylinder. Just make sure you switch to 50:1 mix and your clogged muffler should clear up. Again, thanks so much for watching.

[@chainsawace1777]

I just noticed that you said it's STIHL branded oil that you're using. I've never seen that ratio sold by STIHL, but I may have just missed it. Anyways, switch to the 50:1 mix. Also, the best and cleanest burning oil mix you can buy is the STIHL HP Ultra Mix. It's fully synthetic and comes the in the silver bottle. The orange bottle mix is the standard oil and does not burn as clean as the silver bottle hp ultra.

[@dennisingalls6706]

Just noticed your bar for holding the chainsaw prior to starting it did you design that or was that commercial? Could you possibly take a picture of it and supply it thank you.

[@dennisingalls6706]

Did not receive an answer to either of my questions with regards to saw holder and or sonic cleaner

[@chainsawace1777]

Sorry sir. I missed it. The holder is a bicycle clamp. It fits the bar of a chainsaw or trimmer shaft perfectly. Here is a similar one on Amazon. amzn.to/4aWLws5 Thanks so much for watching!

[@chainsawace1777]

What was your other question?

[@dennisingalls6706]

Thank you for the response. I’ll have to find a bicycle holder. Mr 2nd ?Was what you’re using to clean carbs in sonic cleaner

[@philliphall5198]

They come with the sorry fuel lines and primer bulb period Lucky they last a year 😮😢😢 Carb kit and line’s with new filter every year unless you buy the good stuff 😊

[@chainsawace1777]

I hear you. Thank you for taking the time to watch my video. Have a good day man.

[@SomeGuysSawShop]

So, great job but a compression test doesn’t actually tell you anything about the cylinder, it just shows the rings aren’t stuck and you can tell that without a tester. I personally have saws that are completely scored up but still show 150+ PSI of compression, just something to keep in mind

[@chainsawace1777]

Thank you. Good info. Appreciate the feedback.

[@andybecker2693]

I would save yourself a lot of trouble and just look inside the cylinder by using an endoscope. You could also just take off the muffler. Compression tests can lead you down a rabbit hole.

[@plowmaster1206]

Where do i find that vice?

[@chainsawace1777]

The exact one I have appears to no longer be available. However, a friend of mine bought this one a couple of years ago and it worked great. Here it is on Amazon: amzn.to/3HHnFQV Thanks for watching. Really appreciate it.

[@plowmaster1206]

@@chainsawace1777 appreciate the link and reply.

[@philliphall5198]

Wish we had better fuel line, seems none of it will last 4 years 😢😢

[@chainsawace1777]

Absolutely true. If that long. Thanks for watching.

[@sawyerbennett8227]

That is a terrible fuel filter. Had the same one and it came apart. Junk. Get OEM

[@chainsawace1777]
