Stihl 064 Ignition ???'s

[99busa]

Hello all of you tech guys, I am having problems with my 064. I have recently resurrected this old girl from the dead. It is currently giving me some ignition issues. It was running great for about an hour or two since i built it. Now it quit running. I replaced the old nasty coil wire, and very carefully looked at the yellow and black wires that go to the kill switch, and everything looks good. While i was putting it back together, i kept checking the coil for spark, and it is intermittent. It seems to come and go with tappping on the little module mounted onto the coil. My coil is part # 2 204 222 999 and then it has a small module that the black kill switch wire runs to. I assume this is the rev limiter box?? Is it possible to remove this module, as it seems it is intermmittently faulty. My coil is the three screw mount model. I couldn't find the 064 coil pdf that someone had posted earlier, so i'm lost as far as what flywheel/coil setup i have. (I found the PDF, and my coil isn't there???) It's running right now, but i know it isn't right, because it would fail the spark test while bolting the flywheel cover down, or tapping on the module area?? Any ideas will be much appreciated. Thanks

More Info??

The saw decided it wanted to spark, it started and ran great for a couple of cuts. Then it would start dying when letting off after a cut, but it would restart. After a few times of this, i'm back to no fire?? The coil and module are bosch. I tried it with out the module, that i presume is the rev limiter, since it is tied into the black wire.

Here you go.

Where are you finding part numbers on the coil? The only thing I can find is LIDA and the Stihl Logo. My flywheel has 2 part numbers on the back 1122 400 1204 and 1122 400 1203. On the front the only keyway is cut at position P. I have looked at the old thread and ignition chart but the two part numbers on the flywheel (one key) baffels me. Also I just wrecked a starter pawl and rewind assembly because of WICKED kickback. I bought this saw in a basket and am trying to put it back together. I didn't see how it came apart.

The 1122 400 1204 flywheel only works with the CDIC rev-limiting coil, 1122 400 1303. It's different looking than the usual coils- it's bigger and shaped like a shoebox. Since your flywheel only has slot P, it's the 1122 400 1204.

So what you are saying is I've got to come up with a 1203 flywheel for the LIDA coil? Is that the 2 slot wheel. BTW...thanks Jacob, I do appreciate your help.

 

[99busa]

According to the Chart my flywheel takes a Coil that is Not Available anymore. The dealer said nope. Can anyone tell me what the small module is mounted on top of the coil? The small box confused the dealer even more?

Here is more info for the illusive 064 coil ? I have the flywheel part #
1122 400 1201 a and the coil has 2 204 222 999 on it. I have bought a coil that i thought would work, but it is only a two mounting screw model and the second hole does not line up. My coil that fits has the middle mounting screw offset from being in line with the coil post. My ebay searches have scrounged up pics of a 1122 400 1311 it looks like it would fit if i mounted it upside down. My coil frame looks like that, if the middle mount lug was offset to the other side. I know i'm rambling on, but it's hard to believe there are so many options. Any help will be much appreciated.

 

[99busa]

Any ideas??

Here is a pic of the coil im looking for. The coil that doesn't have the coil wire is the one that i can't find. It also has the small black wire that went to the small black mystery module??

Coil on top 064 is what I think JJ is talking about when he says shoebox coil.
Lower ignition on 064 has no numbers on it, so I don't know what ignition it is.

If your flywheel is 1122 400 1201 then you probably have the 1122 400 1300 coil. The small black box is a "trigger unit", which acts like a condenser in an electronic system. The trigger unit typically is part number 1118 404 3400. Although I'm perplexed as to why some of the 1122 400 1300 coils are fitted with a trigger unit and some are not. I've went through many 064s with the 1122 400 1300 coil that did not have the trigger unit and ran just fine.

The coils that you're showing in your picture though (99busa) look like the 1122 400 1311 (top) and the 0000 400 1300 (bottom).

The coils in Gary's picture are 1122 400 1303 (top) CDIC and 000 400 1300 (bottom). You can see Gary's case on top has both mounts for using multiple types of coils.

Jacob, does the 1122 400 1204 flywheel work with the 1122 400 1311 coil?

Jacob, does the 1122 400 1204 flywheel work with the 1122 400 1311 coil?

Mark- the only way to make the 1204 flywheel work with the 1311 ignition is to rotate the flywheel around about 160 degrees from where it's keyed. The timing is way off for the 1311 or 1300 universal modules. The timing is way off because the CDIC coil has an unusual timing circuit in it. It takes a long time to fire.

I have made the 1204 flywheel work with both the 1300 and 1311 coils but it's a major pain in the butt. I kept mounting the flywheel, trying to start the saw, taking it apart, moving the flywheel, etc. It was miserable. It took me about a good, full hour.

 

[Meadow Beaver]

Oh, well I switched the 400 1300 coil and 1201 flywheel off my saw. I put the 1311 coil and a flywheel that says it's a 1203 and 1204 on the back.

 

[Jacob J.]

If it says 1203 and 1204, then it's a dual-slot flywheel, correct? The 1204 is a single slot flywheel timed for the rev-limiter coil.

That's what I would have thought...but it's a single key flywheel. It rips, I've got it on stock timing with this setup.

It looks like this:

Ok, some of the flywheels made for the interim (i.e. that period of time after they were phasing out the CDIC coils on the 064 and 066) were marked 1203-1204 but were timed for the 1311/1300 coils. I have both here as well. I also have a straight 1204 flywheel that's timed for the CDIC coil that will only work with that coil.

Alright, that makes sense, I was afraid I made a mistake pairing the two up like that.

Can 1122 400 1204 flywheel be modified to be a dual slot?

Hi all.

I have a 064AV with an 1122 400 1204 flywheel and faulty 1122 400 1303 Prufrex CDIC ignition coil.
I've ordered a 0000 400 1300 replacement coil.

Are the (1122 400) 1203 and 1204 flywheels essentially the same, apart from the dual slots on the 1203 flywheel?

If so, is it safe to "find" the correct position for a 1204 flywheel and 1300 replacement coil through trial and error? i.e. Without blowing the engine, or myself, to pieces.

Any advice is appreciated.
