Title: 346xp won't start
Post by: winland on August 25, 2013, 07:25:24 pm
OK, as the title says, my 346xp won't start.
I am not a mechanic in any since of the word, but not afraid to learn and tinker.
May need some "pre-school" advice.  Chainsaw 101 may be too advanced for me.

I have good compression using a compression tester
I have spark, using an ignition spark tester.
I have changed the spark plug.
I only use AV gas.  40:1 mix
Saw ran great a week ago, when last used.
Tried adjusting "L" setting and now back to original at 1 turn CCW
I have tried, starting it every morning for the last 3 days.
Usually get one pop and then nothing.

When adjusting "L", should the choke be on or off?

I removed the air filter to blow it out.  Could some dust have fallen into the carb intake and cause problem?

Can I use "starter fluid" to see if it will kick start it?
Do I spray in the carb or remove plug and spray and replace plug?
Any other suggestions welcome.

when was the last time it ran? 

if has not ran for abit then most likely your needle is stuck in the needle and seat , to prove this that your air filter off and  just dump a very small amount of your mixed gas down the throat of the carb, make sure saw is turned on and see if if it fires .

Now you could be the other way and be flooded real bad , if so take sparkplug out , make sure you turn the saw off so not to blow the coil , flip saw up side down so sparkplug hole is on the bottom and turns saw over easy , if flooded you should see gas coming out the sparkplug hole

Don't be using any ether type spray starter fluid in a chainsaw

Use mix in squirt bottle. Not ether starter fluid.

Fuel line is always the first thing I check.

I got a very nice 350 the other day for free, because it didn't run. All it needed was a fuel line.

Agree, check fuel line better yet replace it and filter if it's over 3 yrs. old.
Shep

Just caught something not mentioned by OP. Was your plug even wet after trying to start?
Title: Re: 346xp won't start

Yes, plug was "wet".

Last evening, I took the spark plug out.
Turned saw upside down, some mix did drip out.
Left it that way all night.
This morning re-installed plug.
Pulled choke out.
Pulled and it popped real nice.
Pushed choke back in.
Nothing, 8 pulls and nothing.

Yep, I've had to replace the fuel line every 3 years since 2001.

But looks like a flooding issue with the one. Still probably needs a fuel line though. ;)

Yeah, I can do this.

Using Firefox on puter. Not smart enough for a smart phone. ;)

Thanks, I'll figure it out.

I'm using firefox and no smart phone here either.  I always ask for the dumb phones when getting new.

I had to "bite the bullet" and took the 346xp to a more qualified mechanic than myself.
Found him on CL.  He is only a mile or so away from me.
Does a bit of dirt track racing and fixes cars/trucks/yard/lawn equipment on the side.
Figured I would give him a try.  What is the worst that could happen?... do not answer that!

He got it running.  Only part he changed was the spark plug, but he said that was not really necessary.
I should keep the old plug as a backup.
He checked the fuel lines.  Said they were good and clean.
He said that he "cleaned" the flywheel area and "cleaned" the clutch area and cleaned the air filter.
He said that the carb was a "gummed up", but I can tell he never removed the carb from the unit, so not sure what he might have done
to un-gum it.  Carb cleaner spray maybe, DNK.

Anyway he got it running and charged me a reasonable price. 
I brought it home and re-adjusted the carb settings and it is running good.

If I had taken it to our local  Stihl/Husky dealer it would have been gone for at least 2-weeks.
I took a broken 28" chain to them 8 days ago to be put back together and I still have not heard from them.

We now return you to your normal channel.

Just caught the tail end of this but I had a similar problem with a 346 but mine would run at only about 8000 rpm.
I even called a trusted mechanic and got him to listen to it over the phone, it worked well on the phone.
I looked at it later and noticed the only difference was the mesh air filter was off because I wanted to be able to see the carb adjuster screws and tell which one was which in case I was told to move a high or low jet.
I could see the mesh had some fines in it but no big deal, so I soaked the whole mesh with a carb cleaner and made it perfectly clean.
Hasn't been a problem since....

I do not think that the air filter had anything to do with this particular problem.
I remember trying several times to start it without the air filter on, so cleaning the air filter did not fix this problem.
There was apparently a "foreign object" of some size and shape that was in a place that it should not have been.

Wish I knew.

Maybe I am going to have to invest in an air compressor.

I pays to keep your saw/s clean! Especially one a good as the 346xp.

Me too, just to know what happened.   

Just like that 371 that would pop and not start. That was a weird one too.

I don't think an air compressor would help with an internal problem.

I still wish I knew what exactly was wrong with mine, I ran the saw for 2 tanks at 8000 rpms, then magically disappears.
Maybe something in the carb plugging a jet, I dunno.
