stihl 009L HELP!!!!!!

[WoodyWoodsWood]

I recently came across two stihl 009's one is an 009L. The 009L was the first of the two and has good compression. I need to figure out how to check the coil for spark. Any help or even input on the saw would be appreciated. Thanks.:deadhorse:

First off, in the future, you'd get more responses if you posted in the chainsaw forum, rather than the milling forum.

But since you are here ...... take the spark plug out, then reconnect the plug to the wire and hold the threads to the cooling fins as you pull the engine over. Should see a blue spark as the coil fires -- but it may be hard to see in bright daylight. Shade or indoors works better.

Don't forget to try a new spark plug, too.

Thanks on both notes I will give that a try

for those of you that have a tacho, there is even no need to remove the spark plug as the tacho will register if you have a spark. It also helps stop flooding the engine when you have left the kill switch on!

I never thought abut that, BobL, but suppose it would work. :yourock:

Also, since he has two 009's, he could try swapping coils, assuming they use the same coil.

And if the coil is not working, it could be due to a leaky ground wire, not the coil itself.

Would a timing light tell me anything at all? Because I checked with one on both saws and got no flash.

Dunno, I've never tried a timing light on a saw. Prolly pretty weak spark just spinning the engine by hand.

Nah - timing light requires using an ignition system that uses a battery. The coil alone makes lots of Volts but only a small current so it will not light a timing lamp, but it is picked up by an electronic tacho.

I'm notorious for forgetting I've left the kill switch on and flooding the saw so now I watch the tacho every time I start.

Those inductive tachs sure are sensitive. I've noticed that merely moving my hand across the tach can trigger a reading. While I haven't tried it, I don't doubt that a tach could pick up the spark signal when starting the engine, as Bob described.

Must be your magnetic personality

A timing light will work on a saw if you use an external battery, I got fire on one of my Mccullochs. But still nothing on those 009's. Guess they have some electrical prollems. Any sugestions now?

So you are saying that you have two 009's, and neither seems to have a spark ? Hard to believe both coils are bad, but anything is possible.

Short of buying a new coil, check to make sure the wire that runs to the kill switch is not accidentally grounded, 'cuz that would kill it.

I agree, last week I sold one that you had to slide in back and forth a few times to get it to fire, not one of Stihls best designs.
