Diagnose & Repair a Weed Trimmer that Won't Start or Run - Husqvarna Fuel Problem Fixed!

How to Diagnose & Repair a Weed Trimmer that Won't Start or Run. This weed eater trimmer came in and the owner wasn't sure what was wrong with it but said it would not start or run.
In this video I will walk you through the process I took to diagnose and fix the problem it had. In the end it had a fuel problem because the fuel lines were rotten and leaking and fuel was not getting to the carburetor. You will see how to install new fuel lines, a new fuel filter and adjusting the carburetor so this string trimmer will run at peak performance.

[@joydavis4087]

We have Husqvarna. We might be able to get it started, but it won’t run unless the choke is wide open. Thank you for this video. We were told it couldn’t be fixed.

[@gulfcoastmike3003]

Overall good troubleshooting. However, with all the bad fuel lines, I would have also replaced the purge bulb. That will be the next likely fuel item to need replacing. Cheap and easy to get to.

[@kcjazzcat7822]

I ended up replacing carb and the fuel lines. I am now using the Husqvarna 95 octane fuel. Works great. I was using regular gas and mixing the oil. I think it hurt the engine. Replacing all of that was worth the money.

[@sunflowermahea225]

Thinking the same

[@Matin_M]

Working on a neglected trimmer that had stale fuel in it for ages. I've replaced the fuel lines and filter, as well as the carburettor. I've gapped the spark plug and tested it for spark, and I've put fresh fuel in with the correct fuel to oil ratio. The thing will not start. It's practically brand new. I think my dad must have run it on straight petrol and worn out the engine.

Old fuel, age and Texas heat no doubt. Thank you, your explanations and great video super helpful! It would help to know what you listening for as adjust carb

Highest idle speed on the low side adjustment and same on the high side but after I get the highest speed on the high side I open the screw about 1/4 turn (counter clockwise) so it runs a little on the rich side to lubricate the cylinder... I have a video on how to adjust properly

if there's a dip stick somewhere on your engine do not use oil in your gas because its a 4 stroke

[@LaurencinStBrice]

Its 2 stroke not 4

[@johnnymariejohnson4293]

This is a 2

[@addmix]

You can have an oil system on a 2 stroke... Lots of snowmobiles, lawnmowers and other 2 stroke engines have oil systems.

My son put the wrong mix in the fuel tank for this exact trimmer. Would you recommend cleaning or replacing the tank? It was never ran with incorrect fuel, I caught it before he got a chance.

[@helpinguonline]

Just drain out the bad fuel from the tank and refill it with the correct mix Of two cycle oil and gas. You are wise not to have run it with the wrong fuel in it… Especially when somebody puts straight gas in a two cycle engine… It will ruin the engine. Keep up the good work!

[@micasa6744]

@@helpinguonline drain it out??? Tip it upside down? Syphon it, how?

[@helpinguonline]

if you mean how to get it out of the carburetor... after you removed the fuel from the tank (take the cap off and dump it out) you can press the primer bulb and that will run the old fuel out of the carb and pull in the new fuel that is properly mixed. that little bit won't hurt anything.

Use only ethanol free gas on any engine with a carburetor. First the alcohol with draw moisture into the fuel and second alcohol attacks all the plastic and rubber parts.

Husqvarna Bush Wacker... I have a heavy duty Husqvama Bush Wacker and I'll NEVER purchase anything made by Husqvama again!!! It was difficult to start from day one. I've had it for about 4 yrs. now and have already had to replace the carburetor (the 3rd yr.). Now, less than a yr. later, it won't stay running unless I have the choke on halfway. I don't even like the way that the design of the Bush Wacker's body, because if you set it down to refill the fuel tank, due to the base design, it falls over to the side. My first heavy duty Bush Wacker was purchased from SEARS. It Was made in China, but it lasted over 25 yrs. Now I feel like taking this Expensive piece of Crap and running over it with my 1 ton truck and sending it to Husqvarna's Head office...!

Have you looked at the piston and cylinder wall and checked if they are scored? There should not be any vertical scratches or scoring. If there is your engine is damaged and will not start or if it does it will run terrible

[@mytycain929]

How do you know if your machine is flooded and if so how do you fix the problem

[@helpinguonline]

No start… Smell gas… Air filter gets wet with gas… If you take the spark plug out it will be soaked in gas. The way to get it started without doing too much is pull it full throttle with the choke on and it may start otherwise you can pull the spark plug out and dry it and put it back in

I have a Homelite brush cutter from 1985. It ran great for 20 yrs. Then I put it in storage for 19 yrs.

It may be something real simple like a clogged fuel filter, cracked fuel line or it may be a little move involved like a clogged carburetor. To prevent this in the future be sure to always drain all your fuel out of the tank and run your weed trimmer til the gas is out of the carburetor when storing. If your carburetor is clogged you can clean it. Here is a video for you on that: kzbin.info/www/bejne/g6XKmJyQm8SrY5Y God Bless you and lead you! Let us know what you find out.
