Husqvarna 345e Hard to start and when it does start it continues to run (chain).

  • Anonymous May 11, 2010

    1 - Do NOT loosen a spinning sharpened chain then operate unless you want to remove a few body parts. I like my parts! 2 - If the chain turns at idle the idle is to high, slow it down. 3. - Hard starting is most often caused by flooding. How old is the saw? are you following the start procedure in the OM? Reply below please.

    the chain is to tight. next to the bar there is a screw that you can back off to get the chain a little loose but dont go to loose as the chain will fall off....good luck

I have a model 435 Husky that had the same hard-to-start problem--warranty service replaced the carburetor and it seems to work ok now. The chain that continues to turn can be fixed by turning the idle-speed screw (not the H or L jet screws) CCW a small amount until it can be accelerated then dropped back to idle to quit driving the chain. Hope this helps!

Hard starting

Starting any chain saw can be a bit finicky. How many hours has the saw done since new ruffle? Over about 10 and the saw would have run in and will need to have the fuel adjusted. What fuel to oil ratio are you running?

Just as a point, you might know this but I only pull the saw over 3-4 times with the choke in. Then try to start with it off.

Tricks to starting 435 husqvarna

There is no trick, push the primer button as many times as it takes to 3/4 fill the bulb ( you cannot over prime it no matter how many times you push it ) pull the red start switch out and at the same time lift up until it locks up, crank the engine twice or until it fires, do not continue to crank, push the red stop button down half way, crank engine until it starts and runs, blip the trigger to bring to idle.

How do you set the chain tension on a 345e?

The E version is tooless, so flip out the wing in the centre of the big cover fixing nut,slacken the nut off half a turn, now turn the knurled adjuster in the side cover, down to tighten, up to slacken, there are many schools of thought about the correct tention of the chain, but basically the chain should sit snuggly all round the guide bar, and with a gloved hand pull manually around the bar with out too much force, it should never sag on the bottom of the guide bar.

I have a relatively new 16" Husqvarna chainsaw, and I have the hardest time getting it started....sometimes I can't even get it started. Once I get it going, it usually runs fine, but it is extremely...

We have a Husky 435 (two year warranty) that was new last year. It would start and run fine for several days, then nothing--took to warranty service where they replaced the ignition module the first time. Ran for several more days, then nothing again--this time they replaced the carburetor and it seems to working fine from then on. Suspect that Husqvarna has had problems with our ethanol-blended fuels. If you still have warranty coverage, then take advantage. Hope this helps!

  1. Check the IPL for your saw to see if any special tools are needed.
  2. There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of starter cord or nylon rope be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
  3. Everyone I have ever removed had a left handed thread (tighten it to loosen it).
    Let us know how it worked for you.

Chainsaw (Husqvarna 345e) will not start due to start attempt without adding oil to fuel.

If this was started without oil in fuel, then the piston is likely scored, and the compression rings stuck in a smeared aluminum mess. You can remove the muffler and probably see the damage to the piston. It can probably be repaired though. Take it to a reputible shop, then read the owners manual and get some help to learn how to safely use and maintain your investment that you have in this saw.
