Husqvarna 445 Chainsaw Run, Bog, Die...Fixed!

[@daniellaris3772]

Been thinking about the small amount of tools you use on most of these repairs and then remember the Big ass tool box next to you. Thanks for all your tips. (I will remember to use my shirt)

[@TheGreasyShopRag]

Ya there are a small amount of tools that get used 99% of the time and a large amount that get used 1% of the time but I suppose those are just as important. Maybe you could duct tape a shop rag to your belly 🙂 BTW I've been thinking about another tool box update.

[@ab-pe2zs]

At the 2:38 mark more or less of this video, I got what I exactly needed. Was trying to replace the primer bulb in a 4 year old 445, and I just needed to know about releasing the carburetor assembly from those little rubber saddles, so that I could get it loose enough to get my fingers in and put the fuel lines back on the replacement bulb. Thanks for the video! Cheers

I really like it when you show the tachometer at the end. It shows that saw is running perfect.

[@jiffleming6500]

When it comes to chainsaw repair you are the MAN I learn a lot from watching your videos. Keep up the great work…P.S. The first thing I would probably have done would be to try to adjust the low or high jet Lol

[@TheGreasyShopRag]

Temperature and elevation can effect the need for adjusting the carb but those screws don't just move on their own (usually) so if the saw acts different in a similar environment then I assume something else is causing it. Sometimes just an adjustment is all thats needed but other times as in this video it can be a blockage in the carb. The trick is doing it enough times to have a good idea which way to proceed. Thanks for watching!

[@jimw6991]

I like your video. Since ultrasound cleaner only takes 5 to 10 minutes why not throw it in and ensure passages inside carb are clean? When you put tach on at the end, what are tuning rpm goals (speed at idle and WOT)? Do you think its necessary to do this speed check or is gettin 4 stroke sound (rich at WOT) good enough? @TheGreasyShopRag

[@nubymizer]

Just found your channel. I am not a tech but enjoy fixing small engines in my spare time. Its a new hobby. Your videos are absolutely incredible for a guy like me. By the way, I have wondered before if people bring in junk brands to your store or just the nice ones that are worth a lot. Keep it up man thanks

[@TheGreasyShopRag]

They bring in all kinds of good and bad equipment. Many times they are warned that we can only fix what we can get parts for. Other times they are warned that a small diagnostic fee could be worth more than the equipment.

[@scottfoster2487]

We has a local vetran that took his old husky into the local saw shop,they procedded to dismantle the saw and told him that is was junk, He went and went to a differnt shop bought a newer saw ,he then tumed around and me and gave the saw to me to do what ever with , I was puzzled because the saw had a nice fuel color and spark plug look amazing pistton was good ,Took the fuel line off and low and behold the fuel line was bad,so I re assembled the saw with a new fuel line and new carb kit, saw started and ran perfect,he was so happy I fixed and wanted to pay me ,I told him I will not take any money from a vateran.

[@TheGreasyShopRag]

I don't understand shops that do this. Either the mechanic sucks or they just want to sell a new saw. The thing is, we make more money on repairs than new saw sales so I don't get it. Good on you for fixing that mans saw.

[@TheKrayusKorianis]

I recently got a 445E X-Torq come to me for repairs. No spark. Fixed by replacing the coil. Then it just does what this video shows, but I did a deep clean and rebuild of the carb and still does it. Cylinder and piston look clean as well. Starts, runs and then dies. Even did a compression test and it's over 150psi.

[@TheGreasyShopRag]

You need to figure out if its dying because of loss of spark or loss of fuel.

[@jorgehetnandez1696]

Did you ever figure out what the problem was??

I had a problem very similar to this on a nearly brand new Echo 620P. I ended up finding that the Impulse Line had come off of the Crank Case fitting. It didn’t even have a clamp on it, but it does now as it takes a lot of disassembly to get to!

[@Black1994ImpalaSS]

Great video! I have a very similar saw. It runs until you shut it off and does it want to restart. The primer bulb never seems to get firm of fill. Removed carb and cleaned well, everything looked good. The bulb seems to seal. I sucked fuel from the tank without issue….yuk!! Put back together. Primer bulb felt firm. Started well and ran amazingly well even idled for 5 minutes while I moved the log with the tractor. Finished cutting . Tried to start and primer condition returned and would not start.

[@TheGreasyShopRag]

If this saw was on my bench I'd open up the carb and look at the micro screen. You could have a partial blockage.

Hi and thank you for the video. I did all you showed and it is still bogging down. What is really strange is that turning the H or L screws does not have any influence. Do you know what else could be wrong? Thank you very much!

[@TheGreasyShopRag]

Maybe a fuel line or the filter. Maybe a big air leak in the engine. Maybe you actually have an ignition coil issue. Lots of possibilities.

[@jaroslavsimecek8452]

Great video. I've got a 445 that starts and runs for about a second and dies. Opened up carb and diaphragms in good shape, fuel screen clean, and carb was very clean. Exhaust screen clean too. I bought a replacement carb and saw does the same thing. I don't see any scoring in cylinder. Could it be the pulse not working to pump fuel? I'm at a loss on this one.

I’ve got the same saw same running issue. New carb, lines prime bulb, fuel and air filter and plug and it still doesn’t work. How do I do a crank case test for the crank seals without making custom plates to seal off exhaust and intake?

[@TheGreasyShopRag]

A thin piece of rubber sandwiched between the muffler and cylinder will work there. On the intake side you have to be more creative. I keep a supply of rubber stoppers. I also have some old carbs that I have filled with silicone. I just bolt them on and its sealed.

[@chrisandsteve5238]

I have a very old 445. Even with regular tunes ups using OEM parts, fresh non-ethanol fuel, etc. the saw is now very difficult to start. I’d like to try replacing all the fuel lines but don’t know how difficult that would be to do. Any tips?

[@TheGreasyShopRag]

Just checked, don't have a video showing that procedure.

[@alexfunke1]

what is the meter/guage that is shown at the end of the video? RPM reader of some sort?

[@TheGreasyShopRag]

Yes, its a wireless, digital tachometer.

[@chrisandsteve5238]

So my 445 has recently become difficult to start, hot or cold. Once it’s running, it runs great. Would you suggest a carb rebuild at this point or is there another diagnostic step I can try first? Thanks for the great videos!

[@TheGreasyShopRag]

You might want to look at the basic tune up routine first. Fuel filter, air filter, spark arrestor screen. Also observe the chain while pulling the starter cord. If it wants to move then you have clutch/oiler drive issues that will make starting difficult.

[@JOEEDE]

I’ve got a 240 that will start after priming and with the choke on. It will rev up and idle fine but then dies. Pump the primer again and it will start again but then die. I’ve put a new carb on but the fuel line from the tank is a smaller line than the other 2. Is that correct? I’m thinking the carb is running out of fuel.

[@TheGreasyShopRag]

Check that new carb. Sometimes aftermarket carbs use the wrong gasket and the impulse hole doesn't line up correctly.

[@steveriggenbach90]

I’ve been working on a 445 and setting the carb. During the initial setup nobody talks about the fast idle screw. How do you primarily set all the screws? Have a great holiday and take care.

[@TheGreasyShopRag]

Every piece of equipment will be different but the key factor would to not have the idle screw turned in so far that the throttle plate is now exposing any above idle fuel circuit. If you have to hold your finger on the trigger to keep it running then bring the idle up enough to release your finger. On the low jet, find that point between between lean and rich then add some rich, adjust idle screw as needed. Check for off idle bog and richen as necessary...adjust idle again if needed.

[@steveriggenbach90]

@@TheGreasyShopRag thank you. You’re the first and only person to give me info on the screw. I can adjust the hi/lo screws. On somethings that little screw was a pain in my butt. Have a great holiday.

[@markluxton3402]

I may be incorrect, but that fuel pump diaphragm doesn't seem to be the best choice for a chain saw. Rubber is a better pumper but doesn't like alcohol in gas. The Teflon ones are also good pumpers and can tolerate the alcohol better. The stiff plastic like one you used can handle the alcohol but is not as good a pumper...I have heard; better for trimmers. I am switching to Teflon as I clean my saw carbs. from now on.

[@TheGreasyShopRag]

Thats probably a good plan but in this case I didn't have a choice. There was one choice and it matched the pump that came new with the saw.

[@markluxton3402]

@@TheGreasyShopRag I only just learned of the differences, though I wondered why my kits had identical diaphragms but different materials. I find it odd that they only provide a Teflon fuel pump, but not a metering diaphragm. It looks like Walbro makes a long lasting metering diaphragm replacement for some carbs.. Better lasting primer bulbs. If "they" would just stop with the alcohol in the fuel, ruining carbs. and causing massive losses in both time and money.
