I realy love both saws they wher great saws took a wile to get use to go from 550 from 346xp and whene the 550 first came out they were having lot of ushues hard start once hot never start if choked onece started. I am doing a 346xp with 47mm big bore never seen 346 with orange side cover of corse i use a silver cover on my 359 eco tec saw nother saw that was awsome no one talks of was the 357 that was a awsome all around machean
The smog saws are sort of chasing their tails. If you reduce NOx the exhaust tends to get dirty and if you clean up the exhaust NOx goes up and that means heat goes up and then you have to deal with the extra heat. It's unfortunate that part of both Stihl and Husky's solution to the heat was to increase the clearance so much. Even completely stock that isn't going to help the top end life any, especially if you're running a low viscosity oil. Plus with the high average cylinder temperature and a low flash point oil you'll get nasty deposits which won't help. Interesting that Husky is using Zama carbs, considering their current owner.
Yeah Robert Cupp....we're good people that know good channels! Have a great day and stay warm.......it's cold down here in Houston but that's southeast Texas for ya.
Did you have the 346 cylinder bored and re-plated to achieve the 45mm bore? Since the factory Husky 45 mm cylinders have the removable transfer covers and what not
Hey Jack, does the 44.3 mm topend just bolt on the OE 346xp like you saw in the video or is modification needed? I love your saw comparison videos bye the way!
Barry hi. The bolt pattern is the same. The port for the pulse circuit may not be the same rouring. Better verify whether you need the early version that goes through the manifold or the later version that uses a hose to a nipple anchored on the drive side by the transfers. Thanks for watching.
So I have a mint 346 NE that I planned on keeping forever. I just stumbled across a like new 550xpg mark 2. I don't need two 50cc saws, Im not sure if I should keep the 550 and sell the 346, or visa versa. Which would you keep?
Coco Bolo hi. That seems like a question you would have to answer for yourself. The Mark ll is the same physical size as the 562. Up .7 of a pound on standard 550. HP increase on the Mark ll is .3 of a horse. The 346 is smaller physically. They feel a little better for maneuverability since they are not so long like the 5 series saws. I'd suggest using them both back to back and see which one cuts better, handles better, and feels better in your hands and then sell the other one. Also many things are not known. Like if your going to mod the saw at some point; if your partial to old school equipment, etc. Best of luck either way. Thanks for watching.
@@hotsaws101 Yeah I was surprised how big the 550 mk2 is. It also seems a good bit heavier than the 346. I had decided to stay away from auto tune, but I couldn't pass up the price for the 550. Thanks for the info! Im going to test both saws tomorrow.
I had no idea there was a full wrap for the 346xp. Cant find any info on it. Can you tell me any more about if this was original or adapted from another saw?
So after some more research, I see that your micro howler 346xp is unique, the “full wrap” was never offered on the 346xp. Yours seems to be a custom job. Maybe made from two half wraps welded together? And while it does add weight as you mention, I really like it.
Fred hi. The factory did not make the full wrap handle or a decent set of dawgs. I made both these two items for this 346xp myself. Thanks for watching.
Robert hi. I am an equal opportunity offender. I like some things about all saws. Conversely, I wish the design of some things were different/better about/in all saws. My job is to help the client end up with a machine that they cannot wait to go and use - one that they are smiling from ear to ear while doing so. It is not to complain about the equipment choice that the guy made. Thanks for watching.
Hey Jack just like to hear your opinion on auto tune vs mtronic have a 562 and a 261cm have had both apart 562 cause it was a 2011 and know One could fix until about 2013 dealer failure and 261 because my buddy at the stihl dealer gets me blown up saws cheap and I rebuild them, both saw run perfect today but mtronic saws seem so much easier with less places to leak air..?
Jessy hi. Both work good when they work good. Both suck when they don't. "mtronic saws seem so much easier" ? The transfer port caps and intake manifold design do add to the air leak potential in the Husky saws. Both the big two smog saws seem a little on the lighter duty side as compared their predecessors. Thanks for watching.
Kerry hi. They are limited by a predetermined upper rpm threshold. A preset if you will, that is built into the Auto-tune system. If the operator can slowly & incrementally squeeze the trigger, I would guess that somewhere around 14.5k the saw would reach the upper limit and start missing. This would put the net around that 13.5k number which is what the tach reads. Thanks for watching.
Sensei948 hi. It's alright. They run around 150 new, before broken in. Sure hope your not using either of the Husky mix oil choices. That won't help the process. The ringlands will get gummed up. Thanks for watching.

Thanx Jack!
Thanks Jack! What mix ratio do you actually use with Motul?
John Bernstein hey good sir. Nice to see ya here. Familiar faces different places
Yeah Robert Cupp....we're good people that know good channels! Have a great day and stay warm.......it's cold down here in Houston but that's southeast Texas for ya.
John hi. 2% with the best overall mix oil that I know of. Thanks for watching.
Thanks Jack.
Wow, 16,000 rpm! I've never heard of any stock saw revving that high. Is the 346 the highest revving production saw?
J T hi. As far as I can remember, the '99 346 was the highest revving saw out of the box. The 246 moved right along as well.
Thanks for watching.

Exelent comparison Jack. Do you prefer husky work or stihl work? What grade gas do you use. And whats ur prefered bar and chain oil?

What’s the Max Rpms you can get out of a stock 550?
