A little muffler mod on my 555 this afternoon.

Nothing fancy, pryed up the hood with a pair of pliers and just enlarged the exhaust hole to about twice the size it was, then readjusted the hood. Hope this opens her up and runs a little better than it already does. We will see.

 

Yep, sure did, should be good to go.

 

What are you guys using for fuel in the 555 ? Just curious. I am on my third gallon of fuel in my 555. Getting a slight throttle hesitation at the start of the cut. Used the Husqvarna premixed fuel for the first gallon and the saw ran perfect with no hesitation. Been using 93 octane w/ Husqvarna 50/1 oil since then.

 

"Been using 93 octane w/ Husqvarna 50/1 oil since then"
That is what I have been using. I have ran about 8 or 9 tanks through my saw so far, No problems yet.

 

Its not really a problem, just seems a little off when I first hit the throttle from idle...slight lag. Thanks for your reply.

 

No problem.

"Used the Husqvarna premixed fuel for the first gallon"
I asked my Husky dealer about this stuff when I bought the saw, just out of curiosity. He said he would not use it that he thought did not have enough mix in it, said he had went round and round with his Husky rep about it. Too expensive for me anyway, so who knows. Sure it is good stuff, just sayin.

Your dealer is probably correct. When I was pouring the premix it looked pretty darn clear. I was thinking hmmm.. does this sh#$ have any oil in it. I just figured that Husqvarna extends the warranty to 4 years if you buy the premix fuel so it must be ok. Anyway no more of that for me either. Like you said way to much money.

Let us know how you mod works out , I'm interested to hear

Jim

 

Sure will Jim.

 

I have not noticed any hesitation with mine, not enough that It caught my attention anyway.

 

Thanks I am going to check this out

 

Do you think this is something I should try ? Or should I just bring it in to my local dealer under warranty ?

 

Some folks run amsoil at 80:1 or 100:1 ..some here even use to run it at that level
It could look clear but since it says 50:1 you have to wonder.

 

I saw the mastermind 066 thread on AS and I decided to never go less than 40:1 which I have always run except 2 gallons of 50:1 last year. Tried some 32:1 and am back with 40:1 as I saw no difference and to save a few pennies on oil.
