Stihl 038 ignition / chip / flywheel

[mortalitool]

Hey guys. hope everyone is enjoying this here nice new forum. Seems to have less BS than the others out there. So I thought id post up my question here.

I have a good old 038 super. I just put a new piston in it, new crank seals both sides. It starts up and runs good for a few minutes then will just cut out. i did notice it has a chip on the ignition coil. Could these possibly wear out over time? I noticed with a quick search on the Ebay for an ignition coil for an 038 that maybe an 044 coil would work as well? If i try this ( i have a few 044 coils ) would the 038 flywheel work ? It gets me wondering with the chip currently on the 038 that it needs an upgraded / newer flywheel ?

Is this true? What have some of you had experience with? The saw passes vac/pressure check. I will look at the carb, but do not think this is the issue...after a few minutes of running it, it immediately cuts out and shuts off and wont start again until cooled down. Leads me to think something with the ignition coil / chip.

Thanks.

Nick

I am not an expert. I think the black square thing is a RF noise suppressor. I hate to admit this, but I have several times now... I replaced a perfectly good coil on a saw that had a cracked spark plug. Exact symptoms you are having. I was checking for spark right after the "shut down" when I found the problem.

Well this is something I should definitely check! Never even thought of that situation. Thanks!

Welcome to old Stihls .That series of saws listed 4 or 5 solid state coils ,5 or 6 flywheels plus a complete points ignition system .What I think you might have is a Bosc ignition which uses a seperate trigger mechanism .

If so the coil is 1117-400-1305 and the trigger is 118-404-1004 if I read the numbers correctly. FWIW the later models all used SEM ignitions probably the most common you'll find .

As best as I can tell, it is like the 028. The replacement coil is the 0000-400-1300, which is on the 044, 029, ms290 and many others. Pop on one of your 044 coils and see how it runs.

Some of them did have the two piece ignition with the little black box. The one piece coils are the same on a bunch of different saws, from 026 to 044.

I dont know if you have to change the flywheel to go to one piece or not, and i don't have an IPL handy.
