044 starting kickback coil flywheel

[langdon19]

Hi all
I just purchased an 044. The pull handle was bust and the owner said (watch out it kicks back on the pull cord)
He was certainly right, got a pop on choke, went to fast idle and bang one pull it ripped that bust core through my hand. Compression was good so bought saw.
Have been advised it’s a 044 12mm in a 440 handle set up.

All looks good, keyway is fine.
Does anyone know if the flywheel/coil is incorrect

 

[langdon19]

Looks like jug has had little use, mine are have heaps more grim

 

[langdon19]

Only thing I’ve found is the spark plug was loose
Maybe it’s how the owner started it with not much pull handle left

Two things to also look at.... starter pawl is not engaging into flywheel correctly. The carb has a leak at the needle seat that is increasing compression.

If flywheel key isn’t sheared off then it could be hydro locking

Could also be a buildup of carbon in the combustion chamber.

Muffler screen blocked?

Change the coil to one for MS460/MS660.

They have a delayed spark advance built in to the electronics.

I forget the Stihl part number.

Don’t use aftermarket as they don’t have the delay feature.

Also drill the decomp bleed port a bit larger. 1/32” or even 1/16”.

Some 044s didn't come with a decomp valve. Mine didn't. Another option is to put an elastostart handle on it. Works much mo better!

Will 7-10 psi on the carb fuel inlet tell me anything with the needle and seat?

I’ll pull muffler and have a carbon check

I can also swap the starter set up with my other 044 I think.

 

[langdon19]

No I have no decomp valve and neither should I need one I assume. If something is wrong I’d like to find out what it is and correct it, I was presuming spark going off to early.

Unplug the spark plug wire then, and pull like normal, see if it acts any different.

Legend, why didn’t I think of that

Yes, It will tell you whether fuel is being forced into the saw possibly causing hydrolock. The carb should hold 7-10psi indefinitely.

I do not know a whole lot about the 044 440 models, were never that popular in my neck of the woods.
However I do know the part number you list for the flywheel is correct for perhaps the earlier period of the series run (at some time they changed to 1214 standard and 1215 Arctic), there was a technical bulletin to support all that- but I am not about to go through boxes of paperwork to find it!
Pretty sure there was a 1200, 1200A and a 1200B but I cannot off the top of my head tell you what if any differences there were between the three.

Looking at your photographs though- that cylinder looks WAY too clean in relation to the flywheel and surrounding areas of the other photos and maybe this saw has been made out of a parts bin. Could be a mixture of old 044, newer 044 and even some 440 for good measure (tank assembly and flippy cap fuel- screw in oil cap).
That is an elastostart handle- the busted one, never seen one do that without breaking the rope first....... if it is a Stihl factory one and not a knockoff copy of a Stihl one. But you want to replace that with an OEM and ensure the recoil is clean, lubed and in good working condition before you try firing it up again.
I know when my 460 bites back, the 70cc range of Stihls can certainly make you take notice! Pulling that broken stub and having it bite back- just looks painful!
