357xp problem

[mattyboy]

Hi,

 

After having used my saw every day for about 5 months clear felling sitka last winter I have used my 357xp only maybe 3 odd days in the last 6 months. At the end of the last day it all of a sudden started over revving so the chain would not stop and if i went to put the brake on the engine would cut out.

 

It has been doing this ever since.

 

Now the fuel I have is the same fuel I have had mixed for 6 months, sitting in my combi can. I have sort of come to the conclusion that this could possibly be the cause and its somehow messed the saw up. Im not a great mechanic so not exactly sure.

 

Has anyone had a similar experience or know definately if 6 month old petrol could have a bad effect and what to do?

Spudulike on here has the answer, it sounds like something that happens a lot with this saw.

The clutch has gone my 357 has done it twice.

Buy some fresh fuel and empty the tank as well!

The petrol will have destroyed the oil in the mix - after around 3 - 4 weeks, the lubricating properties are reduced. Take the muffler off to check the front of the pston.

 

The racing is a classic symptom of an air leak - check the rubber boot - lots in the chainsaw section on this site.

If you are going to be using the saw so little that the fuel mix sits for that many months then i would strongly recommend switching to Aspen 2 which is a ready mixed fuel which doesnt brake down like normal fuel. This means that it doesn't matter how long you have your fuel left in your can!

 

will probably save you a few pennies in the long run and your machine will run a lot better as well!

I can even fire the saws up in the garage without gassing myself if they are running on Aspen but don't really recommend it:thumbup:

I transplanted a engine in a 357 and it always races, is said boot the one between the carb and engine?

Yes, the carb boot, it is inserted in to a plastic holder that has the guide for carb adjustment and impulse line connector on it.

 

The older ones had a plastic clip that was a bit lame so Husqvarna clipped the clip off leaving about 1.5mm gap and fitted a metal band that improved things - there is also a plate that loctes on the uper body of the crankcase and forces the boot on to the cylinder. The nipple that fits in to the cylinder intake also has a tendancy to split so always worth inspecting. I seal with a slight smear of blue gasket just to get it right.

 

If the saw is the EPA model then the automatic decompressor can also play up and would plug the hole in the crankcase and fit the standard one. The EPA model is a US version esigned to meet their ever stringent environmental laws.

thankyou for your replies guys.

 

I have given it in to my local husqy repair man today so hopefully its nothing too major to fix. It sounds like an air like around the rubber boot thing area and maybe need a new clutch if its cutting out the engine every time.

 

Maybe leaving old fuel in there for many months has corroded the rubber boot thing. Is that right?
