Does anyone here have one of these lying around unused that they'd like to part with or know where I can find one? I've got a little 017 that I've rebuilt, but can't run it because the flywheel has been spun on the woodruff key rendering the saw a paper-weight.

Thank you!

STIHL PART 1130 400 1200 - Google Search

Done that dozens of times - not coming up with anything workable. Did you find something you can point me to doing an internet search?

There was an ignition module change mid-production on the 017 that caused a change in flywheel from what I've read on other forums. With the help of the Stihl software, I can see that the parts for the module and flywheel changed together, but I haven't looked at other nearby parts (maybe tonight).

I can't believe that Stihl would have re-tooled the housings for that little saw with the module change, instead making the new module and new flywheel fit what was already there. So, here's my question/theory:

Do you think a newer module and flywheel on an older 017 would work? I can NOT find the 11304001200 flywheel, but I can find the 11304001201 everywhere. The newer coil is readily available too. So, for about $45 in a module and a flywheel, do you think I might make her run again?

Not 100% sure but i think you can just swap in the new flywheel and coil from a MS170. On another forum guys were saying they upgraded a 017 from points to electronic by using MS170 flywheel and coil. See if a picture of a 170 coil looks like yours. The 170 does not have an advance curve in the coil so it can be a direct replacement for a point ignition.

The two ignition modules look slightly different, but I just realized that I have an MS180 that has the two "newer" style parts on it that are the same as the parts you mentioned for the MS170 (the coil and flywheel - SAME part numbers too) that I'm considering putting on the 017.

I'll swap them to see how the fit goes in a few days, see if I can get the correct gap between the flywheel and module, and see if the saw will run with those parts. I'll report back what I find...

Here is a snip out of a tech bulletin.

Fish, you're on the right track! I FINALLY got to trying this swap and this is where I am right now:

I looked VERY closely at the two flywheels when swapping them for this test, and I really can't see any difference in the 11304001200 and 11304001201A units. Moving the 11304001201A flywheel from the MS180C to the 017 runs the 017 quite well, but I am concerned about acceleration, which was the reason for the upgrade by Stihl in the modules and flywheels in the first place from your post above.

I'm going to get an 11304001201 flywheel (not the A extension - can't find what that means anyway) and do a more "permanent" install and test the saw. I'm going to upgrade the coil to the 11304001302 version too. I believe this will solve the problem of not being able to find the 11304001200 flywheel.

Yep. See my post #8 above. I've still got some work to do (and testing), but I think this is going to work

Sam,

How did the conversion work for you? Am in the same boat when it comes to a broken flywheel for this saw. Thanks!

I received the new coil and a used flywheel (P/N: 11304001201A) for the MS-180. That was the saw whose parts I was trying on the 017. The coil did not fit the 017 - the mounting holes are not in the same place. The coil for an MS-170 may or may not fit the 017, but I just don't know.

As for the flywheel, that worked fine. The MS-180 flywheel fit on the taper and key perfectly, just like the old. Since that was as far as I could go, I tuned the L and H screws, and called it a day. The saw runs great!

I suspect that a coil and flywheel from the MS-170 might work, but I am not going to buy more parts for a saw that now runs. It's worth noting, in case it wasn't mentioned above, the reason the coil and flywheel were upgraded for models after the 017 was to improve acceleration (better timing I suspect).

Look at photos (I haven't done this yet) of the 017 coil and the MS-170 coil versus the MS-180 coil. There's a reasonable chance that the coils for the 017 and MS-170 are the same, while the one for the MS-180 is slightly different, but I just don't know.

Hope that helps! S

So I'm in a similar but different situation. I have an older 017 that I bought a replacement motor off Amazon for it. I got the 38mm version and discovered the coil mounting holes are different. Evidently there is and older and newer version of the 017. I believe the newer version changes the mounting holes for the newer style coil. I think it was mainly done to get more airflow around the coil as the old cylinder doesn't even have any fins under it. I know the parts guys I talked to said the older coils weren't very dependable. Anyways I was reading this trying to find out if I needed to change the flywheel as well as the coil, sounds like my old flywheel will work just need to get the newer coil.

Sorry for the delayed update (busy as usual), but this conversion did work in the end...
