Photo of the PTO side with the clutch cover off will confirm if you are building off 064 or 066 cases.
Was the cylinder held on with 5mm or 6mm bolts?
The chain brake flag is for narrow starter so you are on the right track.
Id be looking for an 064/640 starter that had the elastostart pull handle fitted for a non decomp 066 (or 064) cylinder. ;)
 
It has a decompression valve in the cylinder. 6mm bolts hold it down. I can put a elasto start on it. I found a 064 starter assembly on eBay. It’s in rough shape so I’ll have to work on it but I’m still looking for a better one. Hope you can see the chain brake. Sorry for the angle. I did want to take the handle off.

Was the oiler- not so much the chain brake I was aiming for- but the photo you provided shows no brass nozzle or oil line- so not 064.
Did you do a case swap/bottom end swap on this saw- looks a little like you are fitting a shallow starter to newer cases and M10 crank stub.
Can you show a photo of the oil filler cap that includes the front of the crankcase, to check if they are early short cases or later longer ones.
 
I haven’t changed anything. It’s still the short cases and the oil pump doesn’t have the hose on it it has the little rubber o-ring at the top. The crank is a 8mm that’s why I couldn’t get the poly flywheel to work it’s too big.

Was only a guess at 10mm off of the first photo provided. Perfect though, each conformation of type/model helps eliminate possible problems.
Early 066 with a decomp is a rare beast.
 
I’m looking for a double key flywheel for it. The # is…. 1122-400-1209/1214. I have a unlimited coil. Unless you might have a CDIC-A limited coil. The number on that is… 1122-400-1307. It is NLA from Stihl.. if you or anybody would have that coil and is willing to get rid of it then I have a 1209 single key flywheel that would work on this 066.
 
Surprised nobody has mentioned weather a 064 recoil will work with the 1201 flywheel.

I know it's been mentioned on other chainsaw forums. You might try a search.

If the link is verbotten on AS can a Mod remove it. I cut and pasted the post #22 below the link.

"Good thread Huskyboy,
I got three 1122 shelf queens 1986 064, 1992 066 Mag red light and a 1997 066 Mag (last of the strong 066's before they went EPA detuned in 1998).

The two 066's I OEM rebuilt a year ago and had offers $800 CDN for each of them, I couldn't sell they have since been serving my tree service.
The '92 066 is running a 064 flywheel, rewind housing, top cover and a 268XP top handle. No dogs and replacing the dual outlet muffler with the '97 gutted standard muffler saved almost a lb. The '92 066 weighs almost as much as a 046.
It's my ripper saw with 20" ES light.

The '97 066 is a real surprise to me, I thought my older red light was the stronger of the two. But after its rebuild and running 28"-36" it's a real torque monster. I'm very happy to have the last year model of the strong upgraded 066's.
Oh BTW my '86 064AV with race ported cylinder and 084 carb I'm not sure yet what to do with it."
