Husqvarna 55 dies after few seconds (beginner)
« on: February 21, 2015, 11:52:13 am »
Hello everyone,

A few months ago I sought suggestions here on my first chainsaw purchase.
I bought a husqvarna 55 and have been using it with no problems whatsoever.

This morning I planned to cut a lot of wood and cleaned the chainsaw a bit, then sharpened it, covered it in some blankets and rode it over in my bicycle wagon to the other side of town (20 minute ride) where we have our other place.

I have been using Aspen-2 gas. The chainsaw shop I normally buy it from didn't have it last time I went to buy gas and suggested to take the Stihl chainsaw gas instead which works the same way.

I filled up the oil tank completely with chainsaw oil. 
The gas tank had maybe 1/4 of Aspen-2 left and I filled it up with the new Stihl gas.

I put the chain block on. Turned the chain saw on, pulled the stroke. Pulled twice to get the engine started.
 
Then I think just once to get it running. I heat it up a little by pressing the throttle some 3 times (with chain block on. This is the way I have been doing it for some 2 months now), then put the chainsaw on the floor and put up my ear plugs, head gear, gloves, etc. while the engine is running.
Pressed the throttle a few more times while walking from patio to the wood cutting area (40m walk) Then some 25 meters through the engine has died. I tried to start it again where I was, but couldn't.
Went back to the patio, and tried to start it again. But I had really big difficulty. Took a break for some 20 minutes. Then tried again (no choke). The engine would start, but as soon as I stopped pressing the throttle it would die. Then I would have some difficulty getting it on again. 20 minute break, try again. It would start then die after a few seconds unless I kept pressing the throttle. I tried for the last time, after maybe 1 hour break. First with choke, It started. Then normally, and the same thing - it would run until I stopped pressing the throttle continuously and then would have difficulty getting it started again.
I think once or twice there was a little smoke coming out after the engine started before it died.

I'm very much clueless about these things at the moment and would like to hear some advice from you guys.

Thanks a lot -- Adrian

Sounds like the low speed is too rich.  Try turning the Low screw a quarter to one half a turn.

Aclarke: Thank you VERY MUCH!

I turned the low screw 1/4 and the chainsaw started on first pull and works just fine.

aside: What is the best tool to adjust the carburetor? I unscrewed the whole top, then the air filter, then the part air filter is attached too and then used the universal key to turn it. What can I use without having to unscrew everything?

Once again, thanks a lot!

I would advise to stop blipping the throttle trigger with the chain brake on.  The clutch components are not meant to be slipped like that.

Glad it worked out!  Should be able to use a small screwdriver from the outside. Granted it can be difficult finding the slot of the screws in a blind hole.

Ok,

So my cheers were a bit early. Still not working properly.

I went out to cut some wood today. The saw started right away no problem, I barely finished cutting a long piece, some 5 cuts, before it went out again. I could start it right away the second time but just for few seconds. On my 40m walk from patio to cutting area I could hear the engine getting 'weaker' but with each throttle press it went back to 'normal'.

I then turned the low screw (Hmm, I just realized - which way is it ought to be turned!? being very new to gas machines I turned it counter clockwise) 1/2 turn (To make it 3/4 turn altogether) and it wouldn't start at all. I then went 1/4 clockwise and it started but got off after few seconds.

I appreciate the patience, and thanks for all advice.

-- Adrian

Ok, i've read a little about tuning carburetors and yeah, the Low screw of course had to be turned clockwise.
I've spent a day cutting wood today and no problems from the saw.

(fixed))
