husky 350 dish piston
« on: September 13, 2017, 12:37:00 am »
Hi,
I have a fairly nice Husqvarna 350, no pump bubble, it has the low compression piston and runs fine. I hardly ever use it, so I was thinking about the Hyway cylinder kit. From what little I've read they will pep them up some. My question is---does it pep it up enough to be worthwhile, I guess having a noticeable difference. I have nothing in the saw so all I would have in it would be the price of the kit. But if it only makes barley a little difference I'll throw some dollars at something else.
Thanks,
DPJ

I think you'd get better gains from a 353 piston from Meteor, and Caber rings.  Also, delete the base gasket or mill some off the crankcase riser to raise the compression after checking the squish clearance.  I've done this on a number of 350's and like the results.  I also have one with an aftermarket cylinder and found that I had to mill the riser quite a bit just to get decent compression.  Not a big fan of those cylinders other than they're a low cost way to try new things.

Well this cylinder has transfer covers that screw on and sure don't look like it would breath very well. I thought the cylinder transfers on the Hyway cylinder with the four openings just looked better to me, like it would breath better. Oh well, I'm usually wrong anyway so Thanks a bunch, saved me some Bucks. DPJ

            Hyway cylinder?  That depends on which 1 you want to go with.  If its more power your after, than Hyway also makes the 346xp copy.  This will give you more bang for your buck and needs no prepping up from what I have seen.  I have 1 of these bolted on a 350 as well, and is much stronger than stock 350 or a 353.   Its every bit as strong as a OEM 346 44.3mm New edition, and a slightly bigger bore of 45mm as well.   However, OEM prices have come down alot on there 346 xp cylinders too, and not much more than a Hyway 346 copy.  My last 1 was $110 from the dealer.  As for the 350 with 353 piston goes, I don't see alot of difference by using the flattop piston verses the domed when all else is equal at least in my cut times.   The biggest difference by far is the gasket delete.  "Weimedog" had similar results when he compaired his.  Since you have a good running saw, I would just delete the gasket and strive for 18-20 thousands clearance and update with the metal clamp kit, maybe a muffler mod,  and call it good. If its not enough then, you could upgrade to a 346 style jug.  But if you do, only go with oem, Meteor or the Hyway copy.  There are alot of 346 copys out there that have very crude castings and need alot of prepping most of the time.  The Hyway jugs made currently, I know are very good after buying 3-4 units. Two of those kits are still running today as far as I know.  These series of saws is my favorite homeowner line cause there so easy to work on and modify.  I think you will agree too.  Have fun with it.  :)

wild262 Thanks, that was the information I was trying to remember, was thinking of the Hyway Brand 346xp 45mm  type cylinder with the large tranfer ports. This saw was giving to me for putting a new coil and chain on his 435, didn't look like it had been used much. I took it completely apart to clean and check, looked real good, no wear,not very dirty, put back without base gasket, new carb kit an gas line, and a new muffler, hollow inside with a little pipe. It runs fine, seems more power than my 026 but it's an extra saw and I want to play around with it but only if it makes more power
Sorry for being long winded.
Thanks

Sounds like to me you got the better deal.  However they do have there weak points.  The worst is the plastic clamp around the intake collar that are prone to suck air over time.  Also, mufflers that vibrate loose and burn a hole into the oil compartment.  The 45mm's were the worst about this.  Get these resolved and you got a very dependable saw.  Too me there like the small block Chevy.  You can build them mild to wild.  Take care sir.

I forgot to add that you should get a muffler brace from a 346 and add it to your 350.  You have to cut one of the supports off as a 350 has no place to bolt it on to, but that only takes a couple of minutes.

350's are notorious for loose mufflers burning a hole in the oil tank or ruining the threads in the cylinder.  I've used larger diameter bolts but the brace works better for preventing problems.
