If you have a chain saw

Over the years I have owned 3 different Stihl chain saws and all of them at one time exhibited poor operation at high speed after having them a number of years - the problem each time was a spark arrest screen that was located in the exhaust muffler - the screen became clogged and restricted the exhaust making the saw operate poorly - happened again the other day - saw wasn't running good so I opened the exhaust and sure enough the screen was all blocked up - took the screen out and the saw ran like a champ again - just thought I'd pass this info along - what does this have to do with hunting - heck you might use the saw to build your tree stand -

When you buy a new chainsaw you usually get a spark plug wrench with a slotted screw driver on the other end. That slotted screw driver is to punch a hole through that spark arrester screen just after you take your saw out of the box.

Common sense at its best . Good one man .

I moved this from the fishing forum to "Off Topics" just because.

I thought he was going to post about spearing thru the ice in WI. They use chainsaws to cut out blocks of ice.

It seems "he" thought he posted in the Hunting Forum. Hard to tell "his" intentions around here.

Best preventive cure for that is using a good quality synthetic 2 stroke oil from Amsoil, very little cylinder, plug and exhaust fouling.

Yep, that and good high test fuel. Also the screen can be cleaned. Had to do that on my leaf blower after having carb problems and poor running. Poured some lighter fluid on it and lit it. Then carefully took a torch to it to finish cleaning. But I do like the idea of just punching a hole through it lol.

Cleaning that screen should be part of your regular maintenance. It takes 2 mins to clean that every once in a while.

S.

Dont know of any forest fires having been started by faulty saw spark arrestors on a saw--EVER! Its certainly something Id never in my lifetime worry about.
I do recall one fire started by exhaust stack on an old dozer that had rotted through.

I think what happens is the saw doesn't run right and the first thing guys do is start messing with the carb adjustments - only to later find out that the problem is a blocked up screen - that's what happened to me - I just take the screen out and leave it out -
