I'm not sure which, if any, 064's had the see through tank, that photo might be a 066 tank.

As far as the coils go, if you're saw has good spark and you don't need them, someone here would probably buy them from you.

If you bump this thread tomorrow a bit earlier, more folks will jump on board.

Thanks, how would I know if I had the red-light addition?

I think the Red light was rare on the 064. I think it only came out in 1990, just before the 066 took over.

On this photo of a RL 066, see the red dot above the carb adjusting holes (black square) near the air filter cover. Thats the red light.

The air filter is very different on the early ones. It's more like a 026 style where the later ones are the standard oval filters like a 044-088.

" A picture is worth a thousand words ".....no I don't have the red light. Thanks.
 
I too just recently picked up a used 064, so I've been doing alot of research myself. I called my dealer to run the serial number and he said it's not in the system. As far as I can tell mine is a 1984/1985 model s/n 116542800. As others have said the early models have the opaque gas tank and the newer ones that were manufactured concurrently with the 066 flat top have the transparent. The red light was only on the 066. If you have the early model like mine good luck, it's hard finding info.

Everything I read says the 064 came out in 1986.

As far as the red light I got this info from another site: "I worked for Stihl Canada as a tech rep in 1989 and even met Hans Peter Stihl personally at the time. In 1990 the 064 "Brain" was available with the red light technology which a year later in 1991 became the larger cc 066 red light. "

If JacobJ would chime in here, we get to the bottom of it.........

I was told it could be from '85 to '97.....great!
 
Some 064s came with the same rev limited CDIC ignition found on the 066 RL. However, they did not have the red light. When switching to an unlimited coil you have to make sure and use the right flywheel. Some flywheels have two keyways, allowing them to be used with both coil types.

Looks like the shape mine is in!!! What did you pay for it? I picked mine up for 475.00 w/ a 28' and 36' b/c.

Does the limited coil have a specific p/n? Or how can the new bee tell?

I have also seen 1986 listed as the first year of production. But, I've also seen manuals with earlier dates ?? I could very well be wrong, everything is second hand information. Something else I just noticed, some of the 064's have the front hand grips with the deep ribs. Mine has the smaller, smoother ribs and those came out later on. Why doesn't Stihl publish a list of what serial numbers were made in what year?
 
Like I said, in the beginning, I was given 2 extra coils. When I look at the numbers, one didn't have any legible numbers, and seemed to be bulkier, and more square. The second one was smaller, and more round, and its #'s are 1122 1311. Not sure what this means?

My 064 parts list doesn't list that coil out of the 3 listed.
A google search sent me to another site which says 1122 400 1311 is a non-limiting 1994-96 module for the 066. It will also fit the 064.

I don't know about the other coil you mentioned.

It might be time you learned to post pictures.:jester:
 
This is going to be overkill to most, but interesting to some.

Quoted from another site by Windthrown, who some of you may remember from AS before he moved on to other things......

There is a lot of confusion over the 066 'red eye' or 'red light' model saws. Also a lot of confused between the Red Light 066 and the similar limited non red light 064. Even in what has been posted here. You can run an early model 066 red light with the aluminum flywheel with one of the later aluminum flywheel unlimited coils. All the US 066 AL flywheel models should only have one key in the flywheel. I had an AL flywheel on my Red Light 066, and I still have the later Iida coil model from it. It ran fine. The limited coils were commonly pulled and replaced with unlimited ones to run better. This was because the red light coil module would fade out over time and limit downward on RPM's (like 12.5k down to 10k RPM). The non-limiting coils do not have the extra wire and LED lead though. Some 066 red lights were Magnums (mine was), meaning they had the dual port muffler for increasing the 7.3 HP 'regular' 066 to 7.8 HP.

I have the Stihl 066/064 factory ignition module tech sheet that lists the 6 most common aluminum and poly flywheels (there are a whole series of them) as well as all the matched coils. However, there were 9 options in all. There were at least two later models of AL flywheels on non-red-eye 066 before they flipped to polymer in 1996. The red light 066 was only made for a short period of time. They were only made on a very early flat top 066; there was no later model 066 using them. There was an RPM rev limiter in the coil and an LED lead running from the coil to an LED light at the side of the saw. The light lit up when the rev limit was reached and the coil was cutting out. This was so that you could tune the carb H screw to lean it out just until it was cutting out, and the LED light was flashing. For that reason these saws had engines that were fairly bullet-proof; it was nearly impossible to score the engine with the limiter in them. Only straight gassing did them in. Or the bearings went out, as was the case with mine. The swapped out red light and later models of 066 with the AL flywheel and unlimited coil had a common problem with spinning the flywheel side of the crankshaft off because of over revving. So Stihl made the flywheel side of the crank thicker in 1996 and replaced the aluminum with a poly flywheel. They also changed the ignition modules to to advance the timing at high revs on the later poly coils. The AL flywheel coils are straight-line timed ignitions; they do not have an advance curve in them like the poly modules do. The CDIC coils also had a timing retard in them at low speed for easier starting.

In the above post, the 1303 module was in the 064, and not the 066. The red light 066 coil module was a Prufrex CDIC, Stihl PN: 1122 400 1307 (similar to the 064 module, but it has the LED lead). It was changed to an Iida unlimited coil module, Stihl PN: 0000 400 1300, in 1993 and retained the AL flywheel. That was changed to an Iida unlimited coil module, Stihl PN: 1122 400 1311, in 1994. The 0000 400 1300 coil is a generic coil and is still used in some of the new larger Stihl saws. The 064 also had a CDIC coil put in them from 1989, but there was no red light limiter LED. Note that only the 064 AL flywheels have two key slots. This is to accomodate different types of ignition; one was for electronic ignition, and the other was for analog points and condenser ignitions. On these flywheels, B stands for Bosche (old points) and P stands for Prufrex (new electronic).

LOL.....you might be right:msp_smile:. Well, I pulled the fly wheel cover off, and couldn't see any p/n on the fly wheel, but the coil looks real new, and the numbers are 31 9358 (Stihl)....
