There was a recall from Husqy for the muffler retention bolts. That is why your issue is unresolved. Fortunately for me my dealer installed the recall kit when the muffler bolts kept working loose. As I recall they added a bolt to total 3 instead of 2. This happened for me about 2006 A.D.
The intake boot that clips together to hold it to the cylinder is notorious for burning up pistons and cylinders. The clip on the intake boot is not tight enough to make a good seal. They make a intake boot now that has a hose clamp that goes on it and holds it on tight you, might want to think about that before running it too long.
Intake clamp leak caused overly lean condition and stuck ring and scored piston and cylinder .You should remove plastic on clamp end and replace the snap clamp with a screw type.Don't cut off the pulse tit that enables the pump diaphram to operate.This saw will fail again unless you address this issue.Good camera work on what you did......
Thanks. I liked this saw and have the same failure -- due to 87 octane fuel combined with trying to do too much work on a big tree. This is, after all a harry homeowner unit, but like I say I like the saw and will do the overhaul.
Your welcome, they are good saws. I like the feel of it and decent amount of power. I do think they are worth rebuilding when the time comes. I have only ran it once for like 5 minutes after making this video, its not even broken in yet! Thanks for Watching!!!
@@fnaguitarplayer9 did you run it more? I wonder if an oem piston and are better than a whole new aftermarket kit. Someone on a review (might have been a different kit than yours) said the kit has 2/3 the power than the 15 year old worn out oem setup. But they probably did something wrong. You clearly know how to put an engine together !!!
@@fnaguitarplayer9 I restore Husqvarna saws for a hobby now in retirement and these are a nice unit however the OEM parts are starting to get expensive now. The new right side clutch cover case cost me AU$125.00! About US$80.00. I must have a couple dozen saws now all looking very showroom in my home garage! All the best.
Absolutely rough as guts repair job and 75 PSI is no good at all.. That saw needed a full teardown and complete rebuild incl new carb, plus other OEM parts. New Husqvarna bar and saw chain etc. These generally cost me a few hundred in parts to bring back to near new condition.
I would suggest using 2 cycle oil (like you put in 2 cycle gas mix) but I had some 20 weight oil I picked up real cheap and just used that, works pretty good. On bigger 4 cycle engines I'll use lucas or just plain motor oil to put them together with. Thanks for Watching!!!
How to destroy your bottom end while doing a top end rebuild. Beat the wrist pin out with a hammer without supporting the connecting rod... goodbye crank and rod bearings...😔
Pro tip: put fine sand in the crankcase. Make sure to fill up past the top of the bottom end bearing to help hold stuff stiff when you hammer on the wrist pin.
@@callmed.7171 a little bonking didn't hurt anything in this saw. Its a 30 dollar Chinese big bore kit. I would not do it on a tuned race bike / expansion chamber at 14k + rpm
@@callmed.7171 yeah for sure lowered its life expectancy. But I bet something else is going to cook it before that. Air leak/ lean fuel condition. Loose cylinder bolts /bad intake boot.

Awesome video very informative. Are you up for a brand collaboration. We are looking for youtubers to talk more about chainsaw repairing to help more DIY repairers in the community. Hipa supplies small engine parts and a platform that helps DIY repairers get parts easier and more affordable.
I would be interested in starting a TH-cam channel of my own doing that with a sponsorship. I have been doing repairs like this for years. Just have never considered film8ng it
Interesting repair, handy for when I have to do mine. Thanks for sharing!

I’ve poured 1/2 bottle of B12 and kept pumping it there carb and fixed several saws and weed eater 😊

I could see that happening, never thought of that, I will have to check into that! Thanks for the info and thanks for watching!!!
@@fnaguitarplayer9 it happened to my 350. Ran lean because of an air leak and destroyed the piston.
On the older poulan I used zip ties and new boot pretty often
FINE job and now all you need is a log or a tree! BLESSINGS!
Thanks I'm sure it will power through some logs now! Thanks for Watching!!!
And a new bottom end soon after beating that pin out.

Nice 👍
The factory piston doesn’t last long because of the plastic clamp on intake, need a small with screw clamp 😊

I buy used saws and first thing to do is remove muffler and look at piston
Where did you get the part?
Its easier to pull the cylinder with the carb attached.

How much was cylinder kit?
it was around 30 - 40 dollars on amazon. Thanks for Watching!!!
You went from a 45mm to a 44mm and a closed port to a open port. Why??? I don’t understand that. Less performance saw.
Unintentional downgrade bought a kit off Amazon to try out and save a few bucks was not aware it was a different size. Thanks for watching
@@fnaguitarplayer9 great video keep doing more thanks
If it does not run now and does at the end I would call that a gain in performance
@@fnaguitarplayer9 I have a 350 here in Australia however it does not have the push in fuel primer. I'm wondering what year yours is? Many thanks.
What kind of oil do you use to lube the pistion and other parts?

Did he install the piston pin retainer clip?
Yes I did, I did not show it, but I may have said I did it off camera, but yes, it did get put on!!! Thanks for Watching!!!
