Help identifying stihl 460 or 440 ?

[DND 9000]

@thinktwicez71

your ignition module is 1122 400 1314 on the MS 460 (marking 1122 and below that 1314)

@PA Dan

That's a coil from a 660. It should work just fine on the poly flywheel 460. Heres a list of 1122 coils from @definitivedave's thread on flywheels/coils.

Well I popped the muffler off , the piston doesnt look horrible or near as bad as I was expecting , but the back of the cylinder bas me a little concerned , do you think those are scratches on the cylinder wall or aluminum smears ? I will take it apart I just wanted to pressure and vac test it first tommorow

Those look like NWP rings (not a fan!) and the cylinder wall doesn't look good at all.

Scrap that piston and rings. Get a Meteor piston and non FCast rings.

BTW, that does not look like transfer to me. If I had that, I'd hit it with a dingle berry hone.

Dingle berry hone...lol! Got any pics of one of those?

Yeah the lower portion is transfer , I just noticed way up in there it is scratched . I'll see if I can clean this up and make it acceptable to use with a meteor . Hopeing I can reuse this oem cylinder because I'm not fond of aftermarket cylinders

It's a ball hone with cow dung for lubricant

How about the intake side of the piston?

 

[thinktwicez71]

Here is all around it

Damn. The jug can't look too bad, unless someone slapped a new piston in there. Even then, that one's been run long enough that the scratches on the intake wall don't seem to match. Maybe it was an illusion.

You can definitely see the damage from when this broke loose. I bet that's when they stopped using it.

I've also never taken one apart with rings like that.

Nothing is broke off there , it's like a spot that didnt get carbon on it

I'm with Brad - I'd toss that piston and rings.

Dan is correct - that coil will work just fine with your 460 poly flywheel.

That's just carbon.

I believe it did have carbon on it and it broke free!

And smeared down the piston. Most of the scoring is right there.
