Inside the Husqvarna 555

[MacLaren]

As far as weight, I would imagine it would look good as in another thread regarding a 560XP the OP stated it was 12 pounds dry of fluids........BTW, that was surely some positive reppage I sent your way. I just cant imagine why someone would/could negative rep such a wonderful thread...........:msp_sneaky:

When you get the numbers off the 562 you need to also get the timing for the strato opening. To do that you will have to remove one of the transfer covers and watch for when the strato cutaway appears over the bottom of the transfer port window - that's when the strato port starts to flow into the top of the transfer ports.

I expect that the strato timing will be around 10 degrees longer than the intake port timing - that seems to be the case so far.

The longer strato timing is probably an EPA consideration to give a good gulp of air to the cylinder, however it short changes the intake timing. The engine isn't able to start making crankcase compression until the strato port closes (when the cutaway disappears below the transfer port), thus having the intake timing shorter than the strato timing appears to be an emissions consideration. I found that matching the intake and strato timing gave me the best results.

Check the alignment of the transfer covers while you are at it. They didn't align to the ports very well on my 450 and I had to elongagate the screw holes to get the covers in the right position.

Another thing to check is whether part of the piston skirt blocks the strato intake (especially at TDC). You may find that you can trim the piston cutaway a bit to increase the flow.

Probably just a couple stihlheads getting all jealous. :msp_biggrin:

Don't worry, Mitch. I just sent you enough to more than make up for it.

So whats the 555 replacing, The 359??? Seems I got cornfused with the 555, 560, and 562.

359 is correct! :msp_smile:

 

[sunfish]

Dang, that's a great lookin saw!!!



I don't understand the negs???

 

[SawTroll]

The 359 I assume.



Running 3/8 full ch .058 20" and loves it...

Surely pitch and standard bar length will vary between different markets, but I have to admit that the 555 doesn't interest me much - I wait for my 560xpg.....

Anyway, the powerhead design looks like the saws will balance a longer bar than the weight indicates......

Well, I sure hope I wasn't one of the 'miss clicks'. :msp_mellow:

Mitch, I would bout bet money thats what it is. I looked at my settings the other day and I had 80 notifications. All likes. I bet the system messed up.

Comparing a modded and used saw to a new bone stock one doesn't make any sence anyway - just forget it!

It makes no sense if it looses but perfect sense if it wins







I've run the 2156 before BTW and I'm pretty certain the 555 with come in first loser
