Starting up an old chainsaw.....

I was given a Husqvarna 345 chainsaw about 10 years ago and it has sat in my garage waiting for some attention. Based on the engine part number it was built somewhere between 2000-2009, the model#/serial# label is missing. When I was given it the owner said it worked great but didn't start one spring and it hasn't run since. Probably 12-15 years now since it has seen regular use.

I put some fresh gas in it and it didn't want to start. No surprise. Aside from taking apart the carb...any last ditch tricks to try and get an old 2-stroke running?

I was thinking of filling the gas tank with Berryman B12. I'll take the spark plug out and pull the cord a bunch of times to try and get B12 into the carb and let it soak. Then maybe let it sit a few days and then drain the tank and fill it up with fresh fuel. Squirt a bit of oil in the cylinder and reinstall the spark plug. Maybe it will start?

If it doesn't I'll take the carb apart and attempt to clean it out or rebuild it. OEM carbs are going for $140 and the Chinese knockoffs go for $40 which I'd rather avoid. Any tips or tricks? Thanks!
When you do fuel it up use some no Ethanol fuel. It tends to not gunk up fuel system after sitting out a season. I rebuilt the entire fuel system on my Polan. Starts on the first pull everytime.

Big Box chainsaws are never properly set up and are a problem until you set them up yourself. You buy something like a Stihl from a dealer and they are good to go. Now that Stihl is sold at places like Home Depot and Ace Hardware I imagine the same problems.
 
Check fuel lines and primer bulb to make sure they're intact. Dump the gas in it now and put a whole 2.6 oz bottle of 2 stroke oil (I like Echo Red Armor) in the tank and prime the begeezuz out if it to get the oil through the entire circuit. This will soften the more than likely hardened diaphragms. Dump all the remaining oil into a gallon can and remove the spark plug. Take a tablespoon of the oil and put into the cylinder and pull the rope several times to distribute the oil. You can check for spark at this stage. Do NOT put any solvent cleaners in it, that will not play nice with the delicate diaphragms. Put about a half gallon of gas in the can with the remaining oil. Set it all aside for a few hours and simmer. Fill the tank with the heavy premix and attempt to start on choke. When/if it pops, take the choke off and try to start it. If it starts, let it run for a bit then goose the throttle several times if it responds. Then run at full throttle and open and close the choke several times to get the diaphragms to flex. If you wear your arm out trying to start after all this, you're probably going to have to rebuild the carb. You can get rebuild kits for a fraction of the price of a whole new carb. Check out Chickanic on YouTube, she has some good info. Good luck.
Clever. Bet that could rescue some equipment nicely.

Home Depot doesn't sell Stihl, and Ace Hardware sets up Stihl chainsaws & other Stihl OPE for their customers prior to the customer leaving the store (with rare exceptions).
 
I would not trust our Ace to set it up and if they did I would rather do it myself. Probably cheaper at a proper dealer. Wonder if the ones at ace are exactly the same as the ones a dealer sells.
 
ACE is a Stihl dealer, and a Stihl chainsaw is a Stihl chainsaw regardless of the dealer that sells it.
Does Ace prepare them at the store location or at a distribution center? If at the store that could be iffy.

That said, I would get one if I needed it for work. Too expensive compared to my Poulan which has given me great service for occasional use one I set it up correctly.

I havent purchased one from ACE, and can't give a first hand account. From what I've read online, the local ACE store installs the bar and chain, fills the saw with fuel and bar oil, and does a test start and a demonstration of the saw for the customer. I will admit that unless they were running some great sale on Stihl at ACE, they wouldn't be my first choice for where to buy. I have a Farmer's Co-op and a John Deere dealer in my town that are both authorized Stihl dealers. My town doesn't have an ACE.
 
OP, a previous coworker gave me the exact same saw about seven years ago because he said he was tired of trying to get it to run. He isn’t known for his ability to properly care for his stuff so I said sure. Come to find out, it wouldn’t start because the fuel line was completely dry rotted. New fuel line and she’s ripping.
 
Most big box places don't "set-up" a chainsaw, rather, put them together (bar/chain), keep it at factory settings (most often on the rich end for high side) and let it eat. Most home consumers don't even know the benefits of tuning the carb after break-in anyway and manufacturers know this, keeping it simple right out of the box. Most saws are sent out to run well for most customers and not blow up running too lean without adjustment (and probably for the rest of the machine's life). Thats why big box sells so many. It's the service after the sale that makes the biggest difference to those that know and appreciate it.

More often than not, Harry Homeowner will leave E10 premixed fuel in his chainsaw after cutting a few limbs, then put it away for a year without doing anything to it. Then wonder why it doesn't start when he/she grabs it for some more limbs the next spring. Most don't even know what high and low screws are for, much less how to tune a saw to run properly by adjusting them.

That's not a real set up. The carburetor needs to be fine tuned. That's why the ones from big box are so poor. My Poulan ran poorly until I learned how to tune the carburetor. That takes some fiddling until you get it right. Runs great now. BTW all the brands including Stihl are made with chinese parts and are assembled in 3rd world places.

I agree. Since I am not 100% certain what all ACE does before handing the saw to the customer, the only way to know for sure would be to visit a local ACE and inquire. I imagine each store is a different experience.

Had a former co-worker go to work for the local ACE. Every saw they sold were put together, started and run til hot. The customer was given a tutorial and shown how to start the saw, then they would have to do it themselves before the saw left the store. Then the customer was instructed to bring it back after 5 tankfuls of gas to have the carb tuned. They were so adamant about doing this they told customers it would void the warranty if they didn't bring it back in. Everyone did. Pretty high level of service that none of the other ACEs around would do. I liked the place and shopped there from time to time.
 
At least it's not a Poulan chainsaw. You keep pulling and pulling and pulling until it starts. If it doesn't start with all the previous mentioned methods go with a new carb from Amazon or E-bay. Oh shoot this is from September he probably has it running or in the junk pile by now hahaha.
 
I have an old Poulan 3400. If it has sat for any length of time, I just about always have to clean out the carb to get it to run. From then on it runs great.
 
I'd take the thing apart before even attempting to start it. Carb is gunked, fuel lines need to be replaced, etc. Get it over with, then make sure you have a good source of fuel with stabilizer in it. That's a nice saw, and well worth the effort.
Partial clam shell type saw. plastic case. 42mm piston same as 346xp. they run fine if no vacuum leaks. Tune carb to 4-stroke on top end. Replace fuel line and filter, bet it runs.

Poulan Countervibe 55cc saw, all mag case, manual and auto oiler. slower, torquey, pretty bulletproof. No chainbrake.
