Ignition trouble

Mike mandry · Mar 16, 2004

Hi guys,

I have 2 Poulan S 25's

1 with points & 1 with a CD ignition.

I am currently going through both of them.

the one with points has a strong spark & sparks at a relitivly low cranking rpm.

The other one, with the CD ignition seems to have a much weaker spark & you really have to pull it over fast to get anything out of it. You can see the spark consistantly in a dark room, but it just does not stack up to the other one.

I have had the one with points running, but not the one with the weak spark (have never tried)

Both of these saws are like new with very little use. I am just cleaning them up, and puting carb kits/fuel lines/filters & etc in them. You know the usual for a saw that has been sitting for some time.

In your opinion, do you think the one with weak spark is going to run OK, or am I wasting my time on it.

I have checked the obvious (air gap, plug wire & etc..) & all seems well..........

I would give it a try. Ign. modules give very little problems. Usually they work or they don't. Later Butch

Make sure the grounding is good and not corroded or covered with grease, oil, paint, etc... Are all the connections good?

To Mike:

Mike, had a saw that would throw a weak spark and sometimes no spark. I checked out the whole ignition system with a digital Ohm meter. The secondary side of the coil was open and thought I needed a new coil. I got to fiddleing with the thing and found that the coil wire could be taken out of the epoxy coil. I removed it and found that the end of the wire was burned. I trimmed off a bit of the wire and carefully cleaned out the coil where the plug wire was inserted into. I found a small brass like contact at the bottom of the hole where the wire went. I clean up everything, squeezed in some dielectric grease to insulate things and keep the water out. Check it with my ohm meter and had continuety, along with a good spark. The saw has run ever since. Just a suggestion. Lewis.

Thanks guys,

I'm going to give her a try this weekend.

I just have to put the carb back on & its good to go.

I'll let you all know how it goes.

No - go guys, I guess the spark is to weak.

Anyone know where I can get a good used coil ??

It has to be a CD, not points, as they are not interchangeable. The mounting bosses are different.
