Hello,

I need a piston for a 351xp Husky. I wanted to order a Meteor one. Our Meteor dealer website say its the same piston for 350 and 351xp. On Husqvana IPLs are different codes. On Meteor website I have found only a piston for 350. Does anyone know if a 350 piston works for a 351xp ? I know its the same bore 44 mm, but the rest ?
Manny thanks!

Originally (late 1990s) the 350 and the 351 (not an xp) used the exact same 44mm open port top end - and this lasted as long as the 351 was made.
Some time after the 351 was replaced by the 45mm bore closed port 353 (late 2002 or so), they started using the 353 cylinder on the EPA versions of the 350, combined with a dished piston (to keep power output down to the original 350 level. That dished piston is of course best replaced by a 45mm 353 one.

Some late production 351s may have had the same 44mm closed port top end as the late 2149s did - but I have never seen any evidense of this (on the 351).

Sawtroll is right. If it were me & your doing the work yourself, just get that Meteor 44mm piston kit and do a muffler mod. I did this on a 44mm 350 less base gasket and had a nice boost in power. One thing for sure, if yours has the plastic ring intake clamp, replace it with the $15 metal ring/collar upgrade. Now is the time to do it. If yours already has one your ok, just make sure it fits tight on the intake. You should also retune the carb. especially after MMod. These are nice little home owner saws, yours being a 351 a tad better with magnesium case. Have fun.

Thanks folks,

I will order the piston, seems to be right OK. And you are right sawtroll, it is not an xp. The saw is not in my shop, a costumer asked me to order the piston for him, and he told me it is a 351xp. Knowing 351 preceded the 353xp, it was normal for me to think it is a xp too.
As for the muffler mod, I think the man would be more than happy to see it run properly without any mods. He is a homeowner. I will pas the information about clamp in case he has the plastic one.
What do you mean with ”less base gasket”? You removed the gasket and replaced it with silicon ?

The 353 wasn't a xp either, it was the 346xp that was the xp in that model family.

When you delete the base gasket you raise compression which in turn provides more torque. Dirko is the best sealer to use or 1194. You will have to check the clearance too (piston to head). I doubt you will doing this though since you don't own it. If he has the rubber clamped intake, theres a good chance it will suck air and score the cylinder. Very cheap insurance here. Just my 2-cents.

You are right again Sawtroll

.
I know that removing the gasket will increase compression, I was just wondering if should apply the sealant on the cylinder and housing as they are, or have to make a channel, something like a small Stihl has, for example. Then I remembered that Husky does not have that channel. I am more a „man of Stihl” now

, but let me tell you wild262 that 262xp was truly my first love, and it was at first site.

We do not do tunning to saws around here, but I put that on my to do list. In the mean while I try to „steal” as much as I can around here. You, people, share a lot of valuable informations here.
Thanks.

GCC The channel is not needed, just clean both surfaces well, and I allways degreese with alcohol to remove any traces of oil. I apply a thin coat like you would with silicone. Let cure for 24 hrs. to be safe. As far as a love for the 262xp, I would have to say I do too. Look at my user name

. I have an early one and still use it. Has all the goodies, Kolben S. cylinder, HDA 87 carb, Muff. modded, no base gasket, and ported. Runs right with my 272xp. Do you still have yours? I really baby this saw to make it last. Its a blast to use.

If saw has that plastic clamp please make sure to replace with updated metal clamp.

wild262, I saw your user name , thats was I dared to confess myself to you. Unfortunately I don”t have my 262 anymore, but its on my must have list. It really is a wonderful saw. IMO it is reliable and the most easer to repair saw. Some fifteen years ago I could disassemble and reassemble one with my eyes closed.
Right now I really own an a Stihl 200T, Stihl 020AVP, a Solo 606 and I kind of own a Husky 562xp.
