Husky 3120 wont rev - stalls - did a carb clean up and no difference ??!

[chainsaw_louie]

Well folks, I got Good News! The saw started and ran today!  Hurrah!  To celebrate the occasion, I cut up a bunch of firewood. It idled and revved just fine.


The last thing I did to it was remove fuel tank vent and blew it out with compressed air.  My thought was that it was clogged but the air blasted it free and cleared whatever obstruction there was.  When I got the NEW vent, it too had a lot of resistance so I put the original one back in figuring resistance is normal and the saw started up with a few pulls.  After some turns of the low speed jet and then set the Idle and it was ready to go. 

I never put in the carb kit, but will when it arrives, just cause after 2 years it cant hurt.  It was back ordered.

Never replaced the fuel line - did you know they charge $18 for the Husky fuel line Holy Mackerel! I got one on order for the future

Thanks for all the help to figure this out.   I sure learned a lot about how to take care of this machine.   Would there be any interest in posting a flow chart of troubleshooting steps to get a dead saw running?  I could put together a first draft and the others people could suggest additional steps.   It just seems like it would have been an unfortunate waste of money if I had of had the piston and cylinder replaced as someone outside the forum suggested to me.  Am I the only chainsaw dummy here?

Anybody knows where to get Husky parts in the NY NJ CT area, which has a good stock of parts?

Glad you got er going. When that kit comes in, if it's still running good, personally I wouldn't mess with it. If it ain't broke, don't fix it............One thing still puzzels me.

  You never did say if it ran good with a loose gas tank cap. That would have vented the tank. If it didn't...............I think something quirky is going on! And it happens. The saw is running fine. The saw is not running fine. Those are the type of problems that drives people crazy. If it was really crud in the carb, hopefully it kept going. Put that kit on the shelf for later and run the stew out of it!

  No.............the rest of us just don't have the nerve to admit it.

At this point I recall that I did not get a good test with a loose gas cap, .  That was a bit of a challenge for me due in part to the position of the tank - and not wanting to spill the gas.  My cap O-ring is bad and will leak a lot if left loose.  This test would have been an easy way to verify a vacuum pressure problem.  I'll be sure to remember it for the future.  Thanks!

Hey Fellas,

I came across this parts diagram/book on the Husqvarna site, they got these for all their machines.  Its a great help, it has the complete schematic of the saw including clutch, as well as all the parts to the Walbro carb - including that mysterious white plug, I was talking about...

I wish I had seen this diagram when I got the  3120xp
