I just tested the pizz out the 394 in some 20" ash ( least it looked like it)  and I am thinking it was carb issues.   Before testing it started ran like crap shut off and not start. Right now I got it past all of that working on the L and I and H is set fat in the 11's cutting nicely IMO. 

What is the max rpm's on a 394?  Not going there, but like to know.

Doing some reading on husqvarna 394 coil.

This stuff sound right?  Chip?? ?? ?? ?

Suitable Replacement Husqvarna 394 (1992-01) Ignition Coil & Chip



Husqvarna 394 (1992-01) Replacement Ignition Coil & Chip

The Husqvarna 394 (1992-01) ignition coil [module] has an armature and is U-shaped with two ends [sometimes three ends] facing the flywheel. The coil also has two sides. The primary side has thick wire wrapped around one leg approximately 150-200 times. The secondary side has very thin wire wrapped around the primary windings approximately 20,000 times. The flywheel has two imbedded magnets, a north and a south pole. When the magnets pass the U-shaped iron cores on the ignition coil, the primary winding builds voltage up to approximately 200 volts. Then, the electronic control module trigger breaks the current and sends it to the secondary side of the coil building voltage up to 20,000 volts used to fire the spark plug.

The Husqvarna 394 (1992-01) ignition chip is a trigger device that determines when the coil needs to fire the spark plug. It works by breaking the current from the primary side and sending it to the secondary side of the coil. This transfer steps up the voltage to fire the spark plug. The ignition trigger replaces points and the condenser on most chain saws having just two magnets [north and south]. If a flywheel has more than two magnets, then the ignition chip trigger will not work.

Note: On Stihl models 031, 032 and 041 these coils have a spark advance built into them and the ignition chip will cause misfiring.

To test the Husqvarna 394 (1992-01) ignition coil, disconnect the ignition switch wire at the ignition coil. Using a good quality spark tester, pull the starter rope with a good fast pull and check for spark. Removing the spark plug makes this process easier since it reduces the resistance when pulling the starter rope. If no spark is visible, remove the Husqvarna 394 (1992-01) ignition coil and sand the bottom of the coil. Also sand the mounting surface where the coils are attached to ensure a good and proper grounding of the ignition coil. Note: On some saws, the ignition coil bolts onto a plastic housing with a ground wire running to the cylinder or crankcase for a ground.

Good deal on the coil.

Still digging up info for coil options.

((( = coil with part number of 503901201 from husky, trade for a 394 coil;

=  Your coil would actually work on a 394...it's a 254 coil.

=  It would be the same coil as the 394 and some other older Husky saws. I don't know if the coil on the later 395s is limited but the last new
395 I had in my hands (2006 model) had an unlimited coil. It wouldn't be hard to come up with one if you bought a saw that did have one.

It's the same style mounts as the ignitions on the 268 272 51 55 154 254 257 261 262.  )))


Now this might mean you have to retime the flywheel like on the 3120 swap.  I dont know.  But there is a out now.

anyone know or tried this on 394?

394 put through it paces again today in the ash logs.  Coil never gave up.  I think it was just carb issues IMO.   Fattened her up and she is ready to go back out with owner to see if he can get the coil to stop on him or not.   I'm betting not, but who knows, time will tell.
