Took my Echo Chainsaw in to be fixed.

[Chris142]

I have always stored my stuff with Fuel in them. Never had any carburetor problems. I do run them every few months thinking that this may help keep the fuel from gumming up in the carb.

Ran my Echo chain saw about 4 months ago. I had tru-fuel 50:1 in it because it does not contaim methanol. Last time I ran it I let it run out of gas instead of storing it full.

Went to use it today and it won't run right. It bogs , stumbles and just doesn't have any power. Acts like a Holley Carb on a v8 with a bad accelerator pump. Step on the gas or in my case squeeze the throttle and it dies. I'm sure a small jet in the carb is plugged up.

The truth is that I can rebuild Car engines, Car Differentials and even Car Carburetors but I have no luck with Chainsaws and weedeater stuff. If I work on it then it's definatly broke.

Took it to a local shop that specializes in out door stuff and is a Stihl dealer. We will see how they do.

I was having a similar problem with my Echo weed eater. I used some Seafoam (1oz per gallon of my Echo fuel mix). Within 15 minutes I was able to get it to throttle up without bogging. The more I used this mixture, the better it ran. Maybe I was lucky...

Well if it runs but doesn't run well, I would have dumped a dose of Chemtool or something just to see if it could clear it up since it wasn't running right to begin with - just saying

Chemical instant fixes are not what you need. You likely need a new fuel pump diaphragm...very easy fix...

I have never had any luck with addatives plus I don't know how something like b12 would effect the lubrication.I hope its simple like the fuel pump.

StaBil Marine Forumla has a lot of cleaners and is great stuff. Run a tank of gas with it added.

You just need to change your mindset/toolset from big hammers and crowbars to tiny screwdrivers and delicate touch!

Stihl synthetic two stroke oil in the white container.

The chainsaw that I bought last century starts within 3 pulls every time after sitting for a year or more with [censored] gas!

Just for grins, how cold was it? I store all my stuff with tru-fuel in it, and they don't like the cold when I fire them back up. Once I get the normal mix in them, they work fine. If it wasn't very cold, I agree with the previous posts about a torn diaphram in the fuel pump. They will ususally idle OK, and have decent low speed and then fall on their face at higher speed/load.
On a separate note: If they are acting up like that, I usually shut my saws down before something gets busted. If you run something like that saw lean for too long, you'll torch the piston.
The weed whipper I hate, goes wide open until it runs better or blows up!

It was 40(f)ish. The thing did idle fine just wouldn't rev up w/o a lot of throttle pumping.

Shop says the Carb needed to be adjusted, I didn't know these carbs were adjustable other than idle speed. We shall see how it runs.

I bought an Echo CS346 a few years ago. First thing I did was take off the muffler to remove the catalytic converter then I removed the plastic caps that cover the adjustment screws and set up the carb to match the freer flowing exhaust. There was a noticeable difference compared to when in stock condition.
