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
