Saw wont start upon crank. Has compression. No spark. Do I need new coil, on/off switch, or brush kit?? Any light on this would be appreciated.
Experienced gardeners share their insights in answering this question :
The 266 has a two peice ignition system, the electronic pack at the lefh hand side of the flywheel is nearly always the one that goes bad, the air gap should be set at 0.3mm, the coil on the right hand side is never usually at fault.

If the spark plug produces a spark and you are still having difficulties starting your chainsaw, it`s time to check the gap. The spark plug gap is an air gap between the ground electrode and the center electrode. If the gap is too small, the spark struggles to ignite the fuel and air mixture.
If you have an electric chainsaw that won`t start, first make sure that the power cable is connected to the mains, then check whether the cable and plug are damaged. If they aren`t, the problem could lie in the motor which, for example, may have worn or damaged brushes.
Husqvarna 266 SE 20″ 66cc Gas-Powered Chainsaw.
Product Description. A reliable, rugged and powerful saw in 60 cc class. One of Husqvarna`s classic all-round saws for professional applications that require high power, making this saw especially suited to felling tasks.
The Husqvarna Group (Swedish pronunciation: [ˈhʉ̂ːsˌkvɑːɳa ˈɡruːp]) is a Swedish manufacturer of outdoor power products including robotic lawn mowers, chainsaws, trimmers, brushcutters, cultivators, and garden tractors.
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
With a firm grip (i.e. left hand on top handle and foot through rear handle) pull the starter cord 3–4 times, or until you hear the engine `fire`. NOTE: Do not pull starter cord more the 3–4 times while on full choke to avoid engine flooding.
Smart Start is one of Husqvarna`s unique technology because when their chainsaws are installed with it, it means it`s extremely easy to start.

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