What “general test” have you
run and how”? Have you watched any
youtubes or troubleshooting info as at the link below and others in the
area? Good Luck! The cost of a coil is off the Chat and a
Killer if it’s not the problem.

Ck the flywheel key close!!!

I installed a spark tester, which installs between the spark plug wire and the plug itself. There's a small bulb that lights when you pull the cord. I verified the tester works correctly on my Echo trimmer.

I also removed my coil and tested it with an ohm meter. It read within spec for the coil, assuming my information was correct about the spec. However, this morning I read on this forum that someone said a resistance test using multi meter is inadequate for newer coils that have ignition circuits embedded into the coil. I need to rule out the kill switch, but thinking that there is no other option other than the coil. The fact that the coil is 1/3 the cost of the blower really stinks.

PS - I did see the video you shared, which is where I got the coil specs.

1. You did ck the flywheel and key for a good fit “Correct”?

2. I use the same plug tester,
with no spark but got a small Bite to my hand “turning by hand”.

3. I sanded my magnet and
coil “brown vs rust" and fired up afterward with no explanation.

4. Will your magnet hold a ½”
socket? Is the gap approx .010? Can you reduce gap closer?

5. Info on-line sounds like
the coil is an issue. What does Echo say? Will their Rep Shop test it? At that price it should be a sound good/bad
test.

Good Luck!

1. I never removed the flywheel, and it was running before, so I know timing is not the issue.

2. If the energy isn't strong enough to light the tester, it won't fire a plug.

3. Magnet is clean, no rust or dirt.

4. Magnet is strong.

5. Dealer told me it was hardly worth the investment to repair. Suggested I verify it isn't the kill switch, then buying a new coil would be the cheapest option. He can only replace coil if he actually does all the work. Nice.

Thanks for your responses.

So did u or did u not test it with an inline spark tester?

U said u did and got a spark?!?!?, so your problem is not ignition.

I would spray a little starter fluid and confirm if it runs. if ok then fuel problem - check either carb (or fuel hoses that slide in and out easily- need new) or leaking shaft seals (look for leaking fuel\oiil collecting dirt under the flywheel and starter pull cord coils), or if cylinder screws are loose.

Did you get the blower started? having the same problem, no spark on new plug but resistance on coil is within specks. Next move I’m going to test the kill switch.

New coil and plug still no spark
