Old Echo 330 EVL Air Gap

Hi ,


I'm working on an old Echo 330 EVL chainsaw with the two coil system . There are also three magnets on the flywheel together in a row . The saw was sparking some , used a tester to test it and it shocked me a little . Ignition coil was up against flywheel and there was dirt and grease between the coil and flywheel. I took the flywheel off and loosened coil , cleaned flywheel and coil , put back together and set air gap between flywheel and coil with a business coil. Also , cleaned all other connections ( wire , bolt ,etc. )for better contact. Now tester shows that it's not firing . What is the air gap on these saws ? I took spark plug out and used a 1/2 air impact gun to turn crank in order to test as the rope spring is missing . What did I do wrong ? Never worked on anything with two piece coils .Thanks for any and all help .

TomIn,


Thank you for answering my question . May I as where you found that information ? On the internet ? I have one more question . How thick is 0.4 mm (0.016 in.) compared to a normal business card thickness . I was good at math , but that was years ago . Do I have the gap to big with the business card ?

Thank you,
Whizkid

A business card is app.-- .012 and it is not a critical measurement.
One suggestion is to "resurrect coil"--I have not tried this on the two coil setup, but I don't see why it wouldn't work:
Remove spark plug and put a few drops of oil on piston. Leave plug out and spin motor over with--preferably an electric variable speed drill motor. During this procedure, you will be turning the motor counter clock wise and may loosen flywheel retaining nut. I would not use an impact wrench.
You want to spin the motor at app. 2,000 rpm for about a minute or so and I have repaired several coils in this manner.
Others were toasted.
 
If coil leg(s) were against flywheel or there are tracks on flywheel magnets from coil legs,check bearings in saw same may be worn/bad & crank shifting on compression stroke changing coil air gap,IF this is the case you're beating a dead horse as far as coil air gap.

After that goto habor freight,walmart,sears or auto parts store & spend a few bucks for a sae/metric feeler gauge instead of playing guessing games with cards OR goto a hobby shop,model rr shop or craft store that has k&s metal displays & buy 1/4"-3/8" wide X .010"-.016" brass/aluminum strips or 4"x10" brass,aluminum or stainless sheets in sizes wanted,cut a strip from each,paint one end for each size a different color,slip strip between coil legs/flywheel & tighten coil against strip,when strip gets damaged/wrinkled cut a new strip from sheet,I'm still useing orig brass sheets I bought over 40 yrs ago.
 
Another thing to check is for bare or cracked wires, especially to the kill switch. Use a new or known good plug to test for fire. I use the drill method. Make sure the coil is grounded good too.

IME, Echo of that era is not known for having a lot of ignition issues.
 
(quoted from post at 20:30:44 02/08/14) What does spinning it counterclockwise do for it?? I haven't Hurd of this before -obviously
When checking for ignition, engine must be spun over. Counterclockwise is the direction in which the engine runs--facing the flywheel. At least all I have worked on.
A few years ago, I had a concrete saw that needed a $150.00 coil !! I read this procedure on a forum, so I gave it a try--still works good today!

What you're doing is getting the engine going far faster than you will pulling it over for a far longer period of time. It gives the coil a chance to work, if it will work. I don't know about "resurrecting" it, but it is a test to see if it's going to work at all.
