Per JJ  The flywheel side seal (9640 003 1600) is the same seal as the PTO side on 024/026/MS-260/MS-361/034/036/MS-360 saws. The PTO side 084 seal (2250) is proprietary to the 084/088/MS-880.

JJ redneck 084 seal puller   -  A seal puller in those saws isn't necessary. Just take a tuning screwdriver, heat the end up orange-hot, and bend the last 3/8" over 90 degrees. That make a fine seal puller for 084 seals.

084 Ignition trouble
« Reply #154 on: January 23, 2015, 03:18:18 pm »
I've got a 084 that's acting like the timing is off.
It's kicking like a mule when I pull it over, fires, and then floods the cylinder like it's
misfiring or not firing in time.

It has the single notched flywheel 1124 400 1200 which becomes a 1124 400 1203
and this is the coil. I don't know if this is the right flywheel coil combo.

I'm of getting my arm ripped off by this thing.
It's got a brand new OEM top end, complete new fuel system on it also.

Coil gap affects timing a little? But I was thinking a bigger gap retards the timing?

I had a nice 084. I don't remember it kicking in the past?

Last year I went to start it and it hurt my arm and shoulder real bad a couple times before I got it going. It has Elastostart but it got me anyway. I was thinking that I wasn't the man I used to be and wasn't pulling it fast enough? It actually started with the normal amount of pulls.

I sold it!

Perhaps the flywheel isn't the proper p/n?

copy paste  The coil part number 1124-400-1308 is no longer available starting sometime in 2010.

There are three ignition module produced for the 084:

1124-400-1305 Unlimited Ignition Module which requires the Trigger 1118 400 1001 (First Production)

1124-400-1306 Limited Ignition Module (Second Production)

1124-400-1308 Unlimited Ignition Module (Third Production)


Nothing on flywheels yet. But I remember 2 of them at least.

copy paste more info. flywheel is a 1124 400 1203 dual keyway.   The dogleg coil uses the "P" keyway. The 3-bolt coil uses the "B" keyway.


I had one that had a stand alone coil without a trigger. But cant remember which one or fly it had.
