Question about Husqvarna , No.455 Rancher, 20" Gas - Powered Chainsaw
Ignition systems on newer saws are a solid state all-in-one package. Disconnect the kill switch wire from the ignition pack to make sure that the switch isn't broken. Use a fresh spark plug to check spark with. An old one that is black inside is likely shorted. If still no spark, replace the ignition module. Use a piece of card stock to set the flywheel magnets to module gap, then tighten screws

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

Husqvarna says the initial carburetor needle valve settings are from lightly seated 1 turn CCW for both H & L.

Once flooded Huskys are very hard to start. This works well on my 359.

I found an IPL for your saw here:
Enter 394 as model number (no XPs, Es, just the numbers)
Serial number decode – for use with IPL
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week
I chose the 92-10. The coil and wire were manufactured as separate pieces. I found both at Jacks Small engines. It is interesting that the same ignition wire fits a Poulan at 1/2 the cost. About $86 for both pieces at Jacks. HTH
