Husqvarna 1100CD - No spark

[Sean Littlefair]

After spending a way too much money, I've rebuilt a 1100cd Husqvarna. New crank (old one keyway was buggered), piston, rings, bearings. Just got it fired up today.. my first ground up rebuild. Managed to start it, and had it idling nicely, ran for about 10 minutes, then just died. Has no spark at all. even after disconnecting the on/off switch. Has a Femsa CD Electronic coil in it. I guess if I get spark in the morning then maybe it is the coil? do chainsaws behave like automotive coils, as in they do not go when hot? My question is, if it is a crook coil, and I can not get a replacement, would somebody, like a auto sparky be able to repair such a thing? I also have a Husky 480 parts saw. Assuming that coil will not fit. Any suggestions welcome.

Bit frustrating spending about $500 on parts and a few days labouring in the workshop trying to fix it... could be worse i spose... could end up playing golf instead!

No.. definitely no sparkle form the plug... bugger!

Did you swap out the plug for a known good one?
Coil hasn't shifted (loose screws from the rebuild) ? Gap is correct?
No faulty insulation on any of the wires?
Coil can be tested by someone that knows what they are doing with a multimeter- but are not really a serviceable item as such that they can be stripped and rebuilt.
I believe it is possible to swap over to 2100 ignitions- but it involves a flywheel swap to suit and you know the odds of finding a donor saw here eh?

Just sounds odd it fired and ran for a few minutes and then quit after the rebuild, makes me think something rattled loose or found an earth that was not ideal.
Did you have any luck waiting for it to cool fully to try again?
Getting pretty old those saws now, near as old as me!

Thanks, I will try those suggestions. Been busy at work. Must get back into fixing the old chainsaws again
