Makes me not want to ever rebuild my ‘92 Red-eye, lol

After reading through 20 odd pages of threads and going over a bunch of tech notes and IPLs I put this together hopefully it is helpful to somebody. The many fine folks here were invaluable in helping me understand as much of this as I can absorb so far
Pictures at the bottom of the post and corrections/additions welcome.

Thanks to Jacob J for the tons of good info on this topic.

Also attached is some interesting 064/066 documentation in a PDF that I hadn't seen here before.

There are at least two version of the 064 crankcase with different mounting holes for the ignition coils.

QUESTION - I have a flywheel 1203/1204 with a single keyway, when I line up the magnets with a dual keyway 1203 flywheel the single keyway lines up with the 1:00 keyway rather than the 12:00 keyway when viewed from the outboard side. So is this a limited or unlimited flywheel??

Thanks
Dave

44.86 is instructions for stocking parts for the new 064 models
43.86 is an introduction to the new 064 models with all the technical specs, etc.

Thank you so much Dave! I had already listed my 064 for parts on EBAY out of frustration when I came across your excellent work. I had boxes of 066 parts so I replaced my flywheel, mounted an aftermarket unlimited coil, changed to a 066 recoil cover and started the saw!

Very nice

For sale?

For sale?

Yeah, let's get two sent over.
Cash or PayPal is the question.
They look nice and fresh.
The sticker shock should kill us

Aussie shipping is always the deal breaker. $$$$

Yeah eventually when I get bored of seeing it on the shelf!

Otherwise known as a flat top. Just so you don’t get laughed at next time you call it that lol

But unfortunately I don't think it is what is known, over here anyway, as a "tin back" (very early model) or I'd make Tom an offer and keep it here in Oz.

Haha thanks mate!

Tin back is probably more referring to the 064 with the metal air filter cover. This one is plastic. Not 100% certain but I don’t know if the 066 came with the metal air filter cover

 

[RedneckChainsawRepair]

This was at a local pawn shop years back. What you refer to tin back? Was even a arctic.

Nah…a real flat top doesn’t have a decomp

 

[Bob Hedgecutter]

Nah…a real flat top doesn’t have a decomp

Agreed- the decomp puts it in that last variation 1996-98 before the humpbacks arrived.

064 /066 threads are just about my favourite. Well done Tom for giving it a bump

 

[bulletpruf]

Can you use a 1122 400 1209/1214 – 066 double keyway flywheel on an 064?

Thanks

I’ll be bringing this thread up later once I get all these 064/066 parts cleaned and inventoried. I plan on building a few saws and selling/trading the rest. I think I have 5 different flywheels but no dual key. Only 1 10mm crank, the rest are 8s.
The case halves are confusing…3 different coil mount configurations, same pt#. . I’m guessing the 0700/2900 are 064. 0762 is 066? There are a couple others…stay tuned
