Chainsaw Issues

[charliepff]

Since I always lirk I figured I would let you guys take a try at this before I try to fix it or buy a new one. I have a Husqavarna 350 chainsaw. Today when I was cutting I noticed it got really hot. I did not think that was good due to the fact it was about 25 degrees out the whole day. So I refueled it and left it cool down. Well when I came back to run it I cut about 3 logs with it and then there was a thud almost what you would here with the spark plug out and your finger up against the cylinder whole. When this happened I notice the plastic cover move. It would not then restart. So when I removed the cover I noticed the spark plug was out of the cylinder. I though maybe it was loose but I do not think that was it. I noticed all the threads are for the most part stripped out. I have had the saw since 2001 and it gets used extremely hard. I do not skimp on the maintenance either. Is there anything I should look for when I take it apart and is it even worth fixing if the cylinder is shot. Thanks guys ahead of time for the help.

Check with a shop and see if it can be bored out and a Helicoil installed. You can probably do it yourself if you are a bit handy.

sounds like your mix was off in the fuel.

the oil in the fuel is what helps cool the engine. Under oiled will cause it to run hot.

I did shake the mix up before I fueled it but it is old fuel too. I was thinking of the heli coil but I was wondering if I should look to see if anything else is damaged or anyone else have had this happen to them.

Helicoil will fix your head. Id pull the cylinder off and check for damage to cyl or rings too . If theres any scratching, a quick hone and rings will fix you up (should be under $30) Even if you got to replace the cylinder it shouldnt be that bad (around $100 if i remember what i paid for my spacing saw). Put the helicoil in when its off. Pulling the cyl off isnt hard and gaskets are cheap. Id also take a torch and burn any oil or deposits out of the muffler while i was at it. Id definitely try to fix it before i threw it out. I also only use husky oil and fresh "supreme" gas. Im not a big fan of cheap mixing oil.

A friend who is an Arborist told me that too; have done it for years in dirt bike, saws, trimmer etc.

Run Premuim gas, with a good quality oil(I use Husky or Stihl, in the little bottles to mix a gallon at a time). Chain saws are a 10,000+rpm motor. They're like a little race motor.

Thanks guy's for the suggestions. I usually do not run cheap gas. I did not take it apart yet but did price a head. The head was $240 dollars through a online parts store. That was just for the head. I am looking at Stihl specials and will take apart the Husky this weekend.

I know a guy who runs AvGas in his. Says it works quite well. I'm not sure about the legality or health safety of it, though. I personally use 92 octane with synthetic 2 cycle oil.

If you have used the saw well and long it may be advisable to take a serious look at a replacement saw unless the fix on yours is quite inexpensive.

My saw guy told me to run only high test gas, as it will run cooler.
