Hello, had a fairly new 372XP Husq...I don't have the skill or strength to use it myself,  as a scrawny girl, but have a 20 acre wooded campground, so, we need it. I just got it out of the shop, they put on a new carburetor, cost 450.00, the saw was only 4 years old and not used excessively... After a few uses, it locked up, took it back to the shop, they said the cylinder was cracked and it wasn't worth fixing, they suggested someone mixed the oil incorrectly. I saw the oil get mixed, 8 oz oil in 1 gallon gas, so I don't believe that is true...our maintenance man insists they did something wrong in the shop for the carb repair....so, I had to buy a new one...ouch....going forward, is there any way to know if the cylinder cracked due to user error or repair error?  I will not return to that shop, but, if it was user error, I just want to avoid making the same mistake and don't want to destroy another beautiful  new chainsaw!  Thanks for your thoughts...

$450 for a carb or $450 for a new jug?

Actually,  I remembered wrong,  it was 385.00 to put on a new carburetor, they said it wasn't worth fixing the cracked cylnder...

wiam

Seems pricey. Wether it was a jug or carb.  Shouldn't need a carb at 4 years.

Something very fishy here. Improper oil mix does not crack a cylinder and $385.00 is waaaay out of line for a carburetor. Somebody dropped the saw or they don't know what they are doing.

I thought so, too.  Do you know how much a new carburetor should have cost?  Do you know what kind of user error would break a carburetor?

Are you saying the only way to crack a carburetor in a fairly new saw is to drop it?  thx

I hope you at least got the old saw back. It could have been rebuilt way cheaper than that.

It didn't cause your problems but 8 oz of oil to 1 gallon of gas is waay too much.  2.6 oz. of chainsaw oil per gallon is the normal mix.

I would not return to that repair shop to even say "Good Bye".

Oh...I will look into this, thank you very much, I appreciate the education, I read the oil container we had, 2 cycle oil, and it said to mix the entire container into one gallon....True, will not be returning to that shop

louiseM

OK, am feeling pretty stupid right about now, was figuring a gallon was 16 oz., so 8 oz of oil would be a 50:1

This is why I rarely go to the shops around here. They really have forgotten that good fair service is how you build customer loyalty. They just want your money now. Throw it out and buy another one, don't bother me with repairs. Please don't be offended, but my first thought was that they were taking advantage because you are female. Then I realized, the shops around here are equal opportunity, they take advantage of anyone they can, regardless of sex, so it is probably not that. :) I would give my left [anything] to find a shop I could trust, but the two we have to choose from are both [not so very good].
 I just called for some parts a little while ago and neither shop had them. They both said "throw it out and buy a new one, not worth your time to fix". My question is, how do they know what my time is worth, and why do they feel empowered to tell me how to spend my time?
 Keep looking for an honest shop, there must be one out there. (Let me know when you find it, maybe I will ship my stuff there.)

To answer your question about what could have been done wrong. When the carb was replaced if the rubber boot was torn or not properly sealed then your saw would run lean, and could lead to another failure. Not saying that is what happened, but it has been done before. 

If this shop is an actual Husky authorized facility I would contact Husky corporate and see if they are willing to do anything. My experience with them as a customer has been quite positive with repair work.

8 ounces to 16 ounces is 2:1

8 ounces to a gallon is 16:1. Common in years past with old tecnology oil.

Most newer oils are 2.6 ounces to a gallon, or 50:1.

I doubt you could even start a chainsaw with a 2:1 mix. And after pulling the rope enough times, it could lead to throwing the saw hard enough to crack a cylinder.

louiseM

OK, thanks.  I guess the oil I have is old technology, because the directions say put 8 oz into one gallon....good to know, I have that mix in a little 7 lb climbing saw..

To be honest I have never in my life seen a cracked cylinder from a saw.

louiseM

really?  interesting...when I pressed the repair guy to understand the cause he said "a ball-bearing broke,  and bent the pistol,  and that cracked the cylinder...if you want me to be technical"  (add condescending tone)

HolmenTree

Did you ever take or see pics of the damage......odd.....

Yeah im not confident in this shop.  When does a pro saw even need a carb and not just a diaphragm kit?  That price is insane.  Id swap a crankcase out for less. 


Pistons melt and stick to jugs.  A cracked jug sounds hard to do and i have also never seen one in the countless scrapped saws ive rummaged through.  If you had the oil mix you claim, id find it hard to damage a wrist pin or crank bearing.  Itd be swimming in lubrication!   Tear the saw down and show us pics. We can probably tell you how much smoke theyre blowin up your chimney.

When ever I get a shop to repair my vehicles, boat or whatever I always ask to get my old parts back.
Had a few excuses over the years, like "oh the dumpster got hauled away".
Always ask for your old parts back, only time they may refuse is over warranty work. But if it's warranty who cares .

The more I read this the madder I get. That 372 is a great saw and I truly wish I could afford one. Louise, do you do any other business with this shop besides saws? If so, I would cease, but you probably already have. 
 My son brought a saw to a local (supposedly with a decent rep) shop and they ket it for a few days, then told him it needed a new jug, piston, rings, etc. "Just throw it out and buy a new one". I threw some gas in the carb and finds it runs like a bandit. It does need a carb, (12 bucks aftermarket) and some other stuff, but it will run good when I get the time to fix it.
 Maybe I should start a saw shop.

An OEM Carb is around $60-$90 dollars and 15-20 minutes to replace. Anything over $150 is a royal rip. That's a start.
If you put an 8oz can into one gallon, that's 16:1 ratio....a bit much but isn't going to kill the saw, just going to smoke more that you want and eventually will carbon everything up making a mess.
IN the future a mixture of 32:1 would be 4oz per gallon, and 40:1 3.2oz SOME where in that range is safe.
I have never seen a cracked Cylinder...did he say cylinder or case? Seen a few cracked cases! And more than a few with the PTO bearing pocket ruined. That's a bit more expensive as the saw needs to be disassembled a few hours of work and almost $200 in parts, retail. Combination of parts and labor would push to the $350-$400 range using retail prices & typical shop rates. The kind of thing that kills those 372's cases are things like running the chain too tight, or running a really dull chain. The PTO side bearings... Won't expand on that. BUT run enough oil and keep a sharp chain along with proper Technic those 372 last. Be curious what year that 372 was built, that does matter a bit. Newer ones have some significant upgrades to things like the ignition and a few other things making them easier to live with.
