I have a super xl AO 20401307. I am not quite sure what is wrong. I have no spark at all. The saw was my father's and I want to restore it and be able to use it and pass it on to my kids. It has a points setup which look good and I have cleaned the contacts well. I am not sure where to go next. I am more than happy to replace the complete ignition system just having a very difficult time finding parts or the information on what I need. If someone could please help I would be greatly appreciative

The first thing you should check is the on/off switch. They are known to fail. It could also be a frayed wire grounding the coil as well.
To check both, disconnect the on/off switch wire at the coil and check if you have spark.
You should also check the plug wire where it is attached at the coil. There is a threaded barb in the wire well on the coil. Sometimes they become loose over time. If it feels loose, unscrew the wire counterclockwise nip about 1/8" off the wire and screw it back in.
While your in there, make sure the wire from the points to the coil isn't grounding somewhere as well.

First I'd like to say Welcome to HoH! We have a great bunch of very knowledgeable folks here & we're all willing to help. Have you tried a new spark plug?I always say to start with the simplest & easiest thing.If that is good,or you've already done that,then I'd say the condenser is bad.There are 2 different ways to go here - 1) you can get a new condenser,but a new one could be bad too as they can go bad just sitting around 2) you can go with an electronic chip which will eliminate the points & condenser.There is one exception with the condenser & that is to buy one that is tested as good from Bob Johnson in Maryland,N.Y. Seeing that you're going to keep the saw it'd be advisable to get an IPL from Leon who is our administrator here,it's free. Edit:also follow fossil's advice above & check out all wiring.

I have replaced the plug with a brand new CJ6 plug no spark, I disconnected the switch no spark, all wiring looks to be in good shape, no fraying or anything. I removed the whole points and coil bracket? and cleaned it all and ensured good clean mounting no spark. Removed the condensor and made sure that was all clean as well as surface contact area no spark. When I test the points with ohm meter I do get continuity when closed and open when open. I am not exactly sure how to test the coil or condenser.

The condernser cannot be tested with an Ohm meter contrary to popular belief.It's very rare that a coil goes bad.I'd put my money on the condenser being bad.You can buy a chip that replaces the points & condenser on eBay for $12-$15.

That chip is the right one.They're simple to install too.

Just wanted to give an update. I purchased the chip from Amazon. It arrived last night and I installed it this morning. The saw is up and running and sounds great. I will go out and purchase a chain for it today so I have one. Now that I have it running my plan is to take it apart, clean it, scuff it, paint and clear and would like to find a stencil for the bar.

I have a homelite 33"?? Bar. Does rhat bar go to this saw?

Most likely that 33 in.bar is for a C series saw with the F014 mount.Your saw uses the D096/D196 mount.If you could post a pic of the bar,especially the end that bolts up to the saw it'd be great.A 33 in.bar would be too much for a 58cc saw.If it is indeed an F014 mount bar & you have no use for it,I'd be interested in buying it.Glad to hear your saw is up & running!

I see you figured out how to post pics here,hooray! I know how to do it,but difficult for me to explain.Yes,those bars are F014 mount & will not work on your SXLAO.If you'd like to sell the larger one send me a PM.

Glad to hear your saw is running.Beside a bar and chain,invest in a pair of logger chaps if you haven't already.

I would also suggest that since you are planning on taking the saw apart for a complete restore that you get a NEW condenser and set of points and install. I've got engines that are several years old and the points condenser still good. Normally an ignition system will produce a spark with a open condenser (no capacity in UF) but the spark will be weak, no spark if the condenser is shorted or breaking down. I keep a chip around just for testing a saw to see if it has issues other than points condenser.
Chips are great for testing (do not have to pull the flywheel to test) but not for long term reliability in a chainsaw. (I thought the chips were the greatest thing since sliced bread until I started actually using saws that had the chip mods)

Okie,I've got chips in saws where a condenser is no longer available & they're working just fine.I have a friend on AS who uses them consistently without problems.Maybe you're having problems with the chips due to overheating because it's not mounted where it'll cool optimumly,or a poor ground?I also have saws that have an Atom chip that have been on the saws for well over 30 yrs.Of course the Atom chip was much more reliable than the Nova chip (IMO).

Yep, them old NLA atoms were lots more reliable. And the Nova's were mounted in the airstream and properly heat sinked.
The vendor replaced few and they failed and they finally started doing refunds and indicated they were going to stop selling the Nova dues to high failure rate. They were being used (tested) mainly in the old Mac saws, 1-40 through the 250's.
I have some couple of the old NLA Atoms that I save back just for subbing (testing) points/condenser and when the saw is running good I do the points/condenser replacement.
Might be the way I hold my mouth when using (testing) the saw that causes the Nova chip failures.
