Husky 350

[Clint Eatswood]

A friend of mine gave me a Husky 340 that he said didn't work. I diagnosed it and it needed a new chain brake handle and clutch spring. I like to tinker so I decided to turn the 340 into a 350. I got rid of the plastic intake boot clamp and replaced it with a metal one. I got the 350 base plate, and piston and cylinder. I opened up the transfer ports slightly, reshaped the intake and ground and polished the exhaust port. I did not change any port timing as that's above my qualifications (for now). Fired it up today and seemed to run ok. I cut 2 cookies out of a 12" pear tree I cut down last year and it seems to be strong. One question I have is has anybody come up with a innovative idea to prevent this saw from rolling over on its right side aside from felling dogs? I searched but couldn't find anything meaningful.

Thanks for the input.

it is amazing how well they tip over isn’t it? You will probably solve the issue by finding some felling dogs to modify for it. Maybe someone knows of some that are a direct fit.

Same with the 346xps…pita in my truck. Need to make a little saw rack like I had in my ‘77 Corolla hatchback (work truck) in the mid ‘80s

Thread 'Built an OEM kick stand for a 346xp'

I love the saw @t4driller built but I hate that it falls over constantly. It's ridiculous. I really didn't like any after market Spikes and wanted it to be low profile. I wanted something that looked like Husqvarna made it.

@TreeLife sent me two 562 spikes and my plan was to combine one with the 346. I cut both the 346 and 562 spikes and welded them together. The bottom of the 346 tank has a ridge and it needs three points to balance. The shadow in the center in the rear is the ridge of the tank Anyone have access to a water jet? They'd be easy to...

Very cool! Have plasma torch and can heat treat, so.
Is there a link to a write up?
May just play with cutting a spike and coming up with a pattern. Then, take it to a local shop with cnc.

Spikes from a 357XP or 359 are direct bolt on and hang down lower giving a kick stand effect. With a bit of grinding and hole wallering, a set from a 372XP can be utilized with a roller chain catcher making it stand up more gooder. I have one of the flat/pulp wood ones on my 340, with a Stihl catcher.

Thanks for the ideas. I assumed this itch has been scratched before.

I reckon so...

There's some info at that link. I have no idea why the link showed up like a picture, or screenshot.

Click on it, it will take you to the thread here.

I bought a brand new (OLD) one in the box on Craigslist, never had gas in it. Cut some saplings, next year, rev full throttle and die. Changed carb same thing. Checked that intake thing, is tight in place. Someone said the screws from underneath, that hold the jug to the base can be an air leak. POS saw, never put anymore labor into it but it's only had a few tanks of fuel.

Stihl might be the answer. Just kidding, I do like those 350’s but they are rollers like the 346. You’ll never need to worry about the fuel cap leaking on your garage floor!

 

[Woodwackr]

I have a bunch of extra Husky 61 and Shindaiwa 695 dogs so played with one of each.
Test case is a 350 that was easily accessible.
Should work.

 

[Clint Eatswood]

I ended up taking one off a 372 and "wallering out" the holes and cutting a notch to fit the case. Have a 372 chain catcher coming to make it "more gooder". Had to quote you Stump Shot, you're my kinda people.

 

[Clint Eatswood]

I added a 346 muffler brace so this thing is hopefully good to go. Waiting to run it through its paces

 

[Clint Eatswood]

Got the toppling issue resolved. Thanks guys.

Backstory on this saw. A buddy of mine handed me a Husky 340 in a box and said it didn't run and I could have it. The chain brake handle was stripped and it had a broken clutch spring. I decided while I was tearing it apart I would convert it to a 350, because why not. I like to tinker. I ordered the cylinder base and a hyway 45mm piston and cylinder kit. I eliminated the plastic intake boot clamp and installed a metal one. I sanded the base and eliminated the base gasket bringing squish down to .026". Should have pretty good compression, right? Wrong. The saw runs but is unimpressive. I have about 2 tanks through it. I don't have a compression tester but I'm gauging the compression by letting the saw hang by the starter cord. Takes about 4 seconds to fall to the end of the starter rope. How many tanks does it typically take to seat the rings enough to get decent compression?

Have you tuned the carb?. I have a pile of 350s, great little saw!
Did you get the flat top piston or the dished piston?

I tuned the carb where it revs nicely from idle and 4 stroking cleans up in the cut. It's a flat top piston.

You might have an air leak somewhere. I have rebuilt two 350's by a slightly larger top end, usually used on the 353. Both run flawlessly, but it was not easy. he strap connection from the piston to the intake manifold was never a flawless design. I modified that on my two 350's with a machine screw and nut and it worked:

Not an easy fix as shown and it took some careful drilling. Most guys probably just use a Stihl hose clip strap instead.

390xp intake clamps work great on these.

If it was an air leak it would be screaming, sounds like it's kind of a dog.
To me it sounds like it's rich, I like to lean out the high speed screw till it no longer 4 cycles, then turn it back out until it just starts 4 cycleing.
