Husqvarna 359 bogs with throttle on start.

[Greebe]

My Husqvarna 359 that I bought new in 2007 has been a great saw.

However just this week when I started it over several days of work, it is acting funny.

It almost always starts with 2 pulls, but for some reason the past few days when I take the choke off and give it some throttle, it bogs down and won't rev up. If I give it throttle a few times it will then rev up and be fine for the rest of the day and restart just fine.

Gas is fresh. I have only ever used the non-oxy/ethanol free gas and quality oil.

The temps were around 15F, and the saw was out about 15-20 minutes in that temp before start, and the saw was sitting in a bin on the tracksled traveling through the woods at about a 45 degree angle.

Also on inspection I notice I have lost a muffler screw.

All these years I have never had this problem. Any thoughts?

Thanks.

Might just be telling you it's due a service... carb kit, fuel & air filter, spark plug, & tune.
If it doesn't come right after that start digging deeper.
If it has the auto-decomp some came out with remove that asap too

At 18 years, it might need a carburetor kit, etc.

It may be as simple as opening the "L" adjustment screw a fraction of a turn. Sounds like it is not getting adequate fuel when accelerating.

That is very possible. I have always been careful with this saw, but haven't done any of that. It has always just run so great, so I figured if its not broke don't fix it. Awful.

I will look I to getting a carb kit. At one point last year it was leaking a little gas when it was on its side felling trees. That only lasted a day and went away. Seemed a bit odd, but the saw kept running great.

Wonder if there is a small hole in the fuel line, and could that cause this?

Thanks again.

Sometimes to buy you time. Open L up some. Helps if dias getting stiff till you can get a new kit in her.

Cutting some large Ash with her this week. Good saw, but I really need to get a bigger saw. Can't decide between a 372 XP OE or a 390XP. Would also like to be able to mill some of this Ash into lumber, and while the 359 is pretty strong, I don't thing she will be up for that.

Nice. Yeah I can try that as well.

I probably need to order a not Cat muffler as well. Poor girl has been choked by that thing all these years.

I just ordered a 390xp.

Now I need to find parts for form the 359 LOL
