Chainsaws

Tracy and Frank,

I would guess that it is probably the fuel causing the carburation problem, a small amount of moisture will cause the problem with the carburator. I would probably recommend trying a tankful of the canned pre-mix, just to evaluate under the same conditions if that makes a difference.

The difference in the three filters, are a 40 micron filter, and 80 micron filter, and the standard felt filter, and Yes if the air filter is getting wet, and icy then that also could give you the same symptoms, so I would probably try under the same conditions for a test only, and definitely Not during cutting, when you could get any dirt into the carburator, try running momentarily without the filter, just make sure everything in the carb compartment is good and clean before running without a filter, and see if it bogs down then its probably the filter.

I was told by Husqvarna that the 80 & 40 micron filters were for wet conditions, ie, cutting wood when its snowing, etc. and the standard filter could ice up in the winter. I have Not experienced that myself, but I do keep one of my chainsaws with the winter kit installed (which has the air intake partially blocked, also has an air bypass that pulls heated air off the engine cylinder into the carb compartment, and has an 80 micon air filter installed.) I have not had a problem yet with this saw in the winter.

I hope this helps!

Tracey,

Thanks for the feedback and Info, I will be very curious if the cold air kit does work for you. Maybe since the carburator is so cold, it doesn't atomize the fuel and air properly before it goes into the engine, but thats only a guess, and of course once the fuel and air are inside the engine, If the engine is warmed up you should have no problem with ignition.

Is your engine one of the new autotunes ? If not, I would probably also try tweaking the "L" low idle adjustment maybe an 1/8 to 1/4 turn counterclockwise. But wait till you get the kit and see if that makes a difference, if not try a little tweak.

Just remember how far you turned it so you can turn it back to the original setting if it doesn't fix the problem. Also you probably have limiters on the screw adjustments, so you will not be able to adjust it very far from the original settings.

I hope this helps.

PS. Also don't forget in the summertime or when the seasons change to remove the winter kit.

Yes it is the auto tune. As soon as the parts get here I'm planning on helping my neighbor cut some wood so ill let you know how it goes. Thanks again

DJ,

Most of the Winter kits have 3 or 4 parts, you will have to look up accessories for your specific chainsaw model, and it may be listed towards the back of your chainsaw operating manual.

But on mine, I have four pieces, a new air filter which is an 80 micron mesh, and replaces the felt filter to prevent moisture from freezing on the filter and blocking it. Second part is a 1" rubber grommet, you remove the plastic round embossed knockout inside the top cover, this will allow warm air from the cylinder to be pulled directly into the carburetor. And,  In the summer or warmer weather you install the rubber grommet in the hole you created to block the air and prevent overheating in the summer. Third piece is a large, aprox. 4 x 5 " blue cover that fits onto the outside of the starter housing, and blocks some of the allowable air that gets pulled into the engine by the flywheel, and fourth piece is a small finger like piece that also gets fastened to the blue outside cover, and extends through the starter housing, and into the air scoop which is next to the flywheel, this blocks some of the turbo air in the air scoop.

I hope this helps.
