Question about Husqvarna "Chain Saw - 16" Bar, 3 Hp

2 Answers

Starts but when throttled it dies. Will idle all day at idle.

I have replaced the carburetor, spark plug, reset the coil gap. I also removed the cylinder head and checked piston and rings, also removed the sump for seal problems and found nothing. I reassembled the unit and nothing changed.

I'm kinda thinking it may be the coil. It kinda looks like it's not advancing the spark as needed for higher speeds. This saw has me stumped.

After repairing saws for 30 plus years, this one didn't make much sense to me. It's the second time only since CDI ignitions came in that i had to replace the module. I guess it must drive the high speed timing out of wack.

Anyhow, replace the module and unit runs well.

It may be a faulty coil, but if you haven't tried it yet, I would be inclined to play with the settings of the plug.
Maybe a combination of adjusting the plug, and the gap between the contact and the magneto. If that doesn't do it, change the 'cheaper' contact first.
If problems Still persist, you may have to change the magneto.
Good luck with that, hope I've helped you.
Don't forget to rate ;) thanks

Troy-Bilt Hand-Held Blower dies when warm and throttle wide open


You reported that most of the items I would've suggested, you have checked...
Good job.
A couple more things:
  • Replace fuel filter, it's in the gas tank
  • Check and clean the Spark Arrestor screen at muffler, when they plug up, it's a major restriction to exhaust gas flow
  • And check and adjust High/Low screws at carburetor, video attached.
  • And clean or install rebuild kit for carburetor
Good luck...

Instructions
  1. Spark Plug and Sensors
    • 1 Park the motorcycle on its center stand. Remove the spark plug-wire cap from the plug by hand. Loosen and remove the spark plug from the cylinder head with a spark plug wrench.
    • 2 Gap the spark plug to 0.026 inches with a spark plug gap gauge. Reinstall the plug tightly in the cylinder head with the plug wrench. Reattach the plug-wire cap by hand.

    • 3 Detach the wire lead at the fuel sensor on the right side of the cylinder head by hand. Loosen and remove the sensor with a metric wrench. Clean the inner end of the sensor with spray cleaner. Reinstall the sensor securely with the wrench. Reattach the wire lead.
    • 4 Detach the wire lead at the exhaust sensor at the underside of the muffler by hand. Loosen and remove the sensor with the metric wrench. Clean the inner end of the sensor with spray cleaner and reinstall the sensor securely. Reattach the wire lead.
    Throttle and Carburetor
    • 5 Take a position where you can observe the throttle linkage at the left side of the carburetor. Twist the throttle grip at the handlebars slowly as you observe the action of the linkage.
    • 6 Tighten the cable adjuster at the top of the carburetor with a metric wrench in small increments so the linkage responds immediately as you open the throttle.
    • 7 Start the engine and allow it to warm up for three minutes. Locate the smaller idle-adjustment screw and the larger fuel-air adjustment screw at the right side of the carburetor. Turn the idle-adjustment screw to the right one full turn with a screwdriver.
    • 8 Turn the fuel-air adjustment screw to the right or left with a screwdriver as you listen to the engine's speed. Turning it too far either way slows the engine's speed. Find the point where the engine idles at the fastest speed.
    • 9 Allow the engine to idle. Turn the idle-adjustment screw to the left one full turn.
