Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction abates and remove the card. Ensure nothing contacts when the flywheel is rotated.

No fire on echo pb200 leaf blower


I would check to see if the spark plug is firing first off and if it is ok check the plug wire and make sure there is no damage to it. If that is ok then you probably have a bad coil. You can use a spark plug tester and see if you are getting fire from the coil if not you will need to replace it. If you change the coil be sure to note the air gap between the coil and the flywheel then set the new one to approx. the same distance. Hope this helps.

How do i adjust the coil on a echo pole saw to get the right gap to make it fire. and also is there a way to check the coil to see if it is firing


The correct air gap is 0.3mm, slacken the ignition unit screws, slot a feeler gauge passed the ignition units metal core, turn the flywheel around to allow the feeler gauge to get sandwiched between the units core and the magnets, now re tighten the screws. If the machine still has no spark, i fear it is a new ignition unit required.

Need the air gap between the ignition coil and the flywheel for an Echo PB-251 leaf blower


All magnetos work best with minimal air gap. Gap it with the thinnest piece of paper/plastic that you can remove from the gap. Spin it, examine flywheel for evidence of rubbing. If it's good, start it and zoom it a couple of times, shut it down and check again.

Air cap on ignition module Echo PB-413H blower


The air-gap between the ignition coil module and the magnets of the flywheel is a close tolerance. It is adjusted to about .010"-.012". This is approximately the same as the thickness of a standard size business card. I double the cover and let the magnets on the flywheel (lined up with the coil legs) pull it in tight 9compressing the paper card) and then tighten the adjustment screws. The screws have been known to vibrate loose and the gap would be lost. You can use threadlocker on the screws (optional) or just tighten them down well. Too large an air-gap is bad, but the closer the air-gap, the stronger the spark.

Replaced coil an still no fire out of wire kill wire is not hooked up


Hello,
My name is Dane and I am going to help you solve your problem. Ok, there aren't many things that can cause you a problem here. First, I have to say to check that spark plug. Make sure it's correctly gapped and not cracked or fouled. Now, check that the flywheel is clean and rustfree. Make sure you have set the coil gap correctly.

To set the gap for the coil, get a regular business card and use it as a feeler gauge. Turn the flywheel so the flywheel magnets are away from the coil. Loosen the bolts to the coil, and pull the coil back, making the gap as large as possible. Rotate the flywheel so the magnets are next to the coil. Slide the business card in between the coil and the flywheel magnets and loosen the coil bolts. If your coil has 2 legs, make sure the business card is under them both. Make sure the coil is even and just snug against the card. Now tighten down your coil bolts and spin the flywheel to remove the business card. Turn the flywheel at least 1 complete turn and make sure it doesn't contact the coil. You're done!!! Put it back together and try it again. It's not unheard of to get a bad new coil. Don't think just because it's new it has to be good.
Well, I think this should get your problem fixed. Thank you! Dane

How do you test the ingition coil on a echo 16 inch chainsaw?


Remove the ignition switch wire from the module. Set the module pole gap by turning the flywheel magnets under the module poles, insert a thin business card into the gaps, and loosen the module screws to allow the module to contact the magnets. Tighten the screws and turn the flywheel somewhat to release the card. Turn the flywheel one full turn to make sure the gaps don't close up at any point. Test for a blue, snappy spark at a fresh plug gapped 0.020". If nothing or very weak, replace the module. Hope this helps!

Igntion coil on echo trimmer went bad, replaced with echo blower coil . there is a small difference in design but now have ignition. Engine still won't start.


Make sure the air-gap between your used blower coil module and the magnets on the Echo's flywheel is about the thickness of a regular business card. That is about .010"-.016". The gap HAS to be present in order for the module to produce the spark.

I need coil and spark plug gap settings for echo hc 1500 type E2 hedge trimmer.


0.026 inch, or 6-8 mm is the plug gap.

The ignition coil air gap range is 0.012 - .016"" or .3 - .4 mm. This is the gap between the flywheel and the ignition coil.

An easy way to gap your coil is use a normal business card between the coil and flywheel, tighten the screws and remove the card.
