e ignition coil is ok since it starts fine. Anyone know what it could be?
Experienced gardeners share their insights in answering this question :
Hi,OK. The kill switch breaks the circuit to the plug. Since you replaced the kill switch, assuming it is good (did you test it with a multimeter?), the problem has to be in the wiring to the plug from the switch. If the plug gets power all the time, then the circuit is complete all the time. I’d replace the wires from the switch to the plug.Hope this helps. If it does, I’d appreciate a 4 thumbs up. Thanks,Handie Andie

In a kill switch setup, the switch is normally not creating a circuit, which allows the engine to start and run. When you want to shut the engine off, the switch is depressed and held. This creates a circuit to ground which shuts off the engine. The ignition switch is turned on or off to control the ignition circuit.
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel will evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.
When a kill switch is engaged, it prevents an electrical circuit from completing. When a button is pressed, the kill switch can disengage, completing the electrical circuit, and allowing the necessary electricity to flow to the car`s ignition system.

Kill switch doesn't work, how do i fix it? – Husqvarna 350 18 Inch Gas Chainsaw 52CC Fully Assembled Brand New 18"
The switch connects directly to the coil body of the ignition module. You may have to remove the left side cover to expose the ignition module. The switch, when off, connects this wire to engine ground. There may be debris in the contacts of the switch that prevent contact. You will have to remove the air cleaner assembly and maybe the carburetor itself to access the switch. Good luck!
My chainsaw has no spark, I have checked the spark plug and it works on another unit, i guess it may be the ignition, ho0wever as it is a small coil I have no way of checking. can the coil be simply tested, otherwise can one be purcahsed.
Yes the coil can be tested. you would need to know the proper specs but with a multimeter you should be able to get a resistance value from your plug wire to ground. With my experience 10000 – 30000 ohms should allow it to run. If this is no help one common thing is your kill switch. A wire should run from the coil to the switch, if this wire is shorted to ground it will not run.
I have an older Kubota tractor, model B7100 HST. Was running the tractor and had electrical smoke/short? Took the dash off and noticed that the regulator was fried and melted no other apparent damage. I assumed the problem was within the regulator……..bad mistake. Bought a new regulator. Hooked up all the wires and started the tractor. Seemed to run fine and shut it down. Used the tractor for about 10-15 minutes the next day noticed smoke once again coming from under the dash. Shut the machine down. Everything within the dash wiring bundle was fried. I mean really messed up. Wires were melted together new regulator was toast – literally! So I assumed once again that there was a short within the dash wiring bundle since none of the damage occured past the main connection between the dash and the wiring bundle that leads to the rest of the engine, starter etc.
I ordered a new complete dash wiring bundle, and new regulator. Hooked it all up and turned the ignition key and smoke just started again. Unhooked the battery immediately. Seems I caught it in time without doing any damage – I hope. The only thing I have not changed within the dash is the ignition switch. Spoke to one of the machanics at Kubota and I suggested perhaps it was the igntion switch? He didnt think so but didnt really know what to suggest. He suggested looking down the entire length of the wiring bundle for any wires that maybe have worn through and “gone to ground”. I have looked but nothing is apparent. I should also mention that in all instances NONE of the three fuses within the dash have blown. The fact that none of the other part of the wiring harness past the dash main harness connection makes a person believe the problem is occuring within the dash? I’m thinking of replacing the switch.
Any advice would be appreciated.
It does sound like a dead ground inside the ignition switch and I don’t know why the mechanic didn’t tell you that since it’s not the first time they have heard about this issue.

Check and make sure the wires are plugged into switch.If that don,t work it has a bad switch.
Why will my saw not start, good spark new plug fresh gas
Sounds to me like a plugged up fuel line or old fuel in the fuel line. You may be able to clear it by spraying some starting fluid into the carb to pull the old fuel through. You only want to do this 2 times because this has no oil in it. Another suggestion it to remove the spark plug and put some of your fresh fuel mix directly into the chamber. About an eyedropper full should work.
Poulan pro 42 cc 2 cycle chainsaw ignition coils keep burning out
It is not common, but there are so many poor quaility units out there it does not surprise me.
I have a 2.5 turbo craftsman chainsaw that I just rebuilt the carb. this chain saw was given to me and was not working when I was given this gift I knew it had worked before knowing the people that gave me the chainsaw. I got the engine running with the rebuil then it would not turn off. I had pull the plug wire. though maybe it was the switch, but the parts store tested and said the switch was fine. I checked to see if it had come undone from the ciol, but it had not. I disconnected the switch and it will still start then while it was running I tried to connectthe two wires going to the switch thinking it would turn off, but it did not. what do you suggest?
Hi, if you short the kill switch terminal on the coil and you still have spark then the earthing circuit inside the coil is fried. If this is the case the only way to fix your problem is replace the coil. Regards Phil.
