I looked up a flywheel and get part number1140 400 1209. Has been changed four times. 1200, 1204, 1207, 1209.
The 1302 module looks right. Make sure there is a ground to the case.
You may not get a spark using a drill. I always use the starter when checking spark to turn the flywheel fast enough.
As far as the magnets, should only need 1 good set to fire non mtronic, just like any other regular ignition. Will have to remember to check this on the next 362 I get in the shop.

A fly wheel is nothing but a disc with some magnets. Why would Stihl need to change it four times?

That's a Mtronic saw, right?

 

[pioneerguy600]

Wasn`t there about 4 different versions of the 362? My 362 was the early carbed saw, it has been so good to me that it has stuck around and I prefer it over my ported 036 PRO and MS360.

In the title OP states its not Mtronic....early reg carb. My dealer had 2 auto carb 362's on the shelf but I asked him to order the non Mtronic which he did. There are several threads on this issue right now.

The new coil you bought is it OEM or China knock off?

stihl from the stihl dealer part No.1140-400-1302 and it is working

 

[stihltech]

Maybe I missed it, but you are trying the spark with the switch wire disconnected at the coil, right?

Well, then the only thing left, is the flywheel.
What do you mean the coil is working now, there is spark?

 

[Ed Penney]

thanks for your reply will check the earths i did sand the place were the coil is bolted to the crankcase but will do it again and get back to you again thanks petemack

Should be grounded on the cylinder not the case. In some cases the base gasket or sealer will negate the ground.

How are you checking for fire ?

If all else fails stick a nail in the spark plug boot and yank it while holding the nail with the side of your hand on the cylinder.

The best way is to check spark in the dark.
