Fit perfectly except had to bend a small tab at the back of coil flat.
Didn't have to do any grinding. Saw is reving to 13000 no load. Unscrewed the short coil wire and installed the wire from the limited coil. Next step is a mild muffler mod (any suggestions) and enlarging the high speed jet in carburetor to richen it up a bit. I have  seen 1.16mm as a possible size ?

I would be conservative with enlarging the high speed jet a little bit and then see how it runs so you can ease up onto the perfect size?

If you are the ham fisted type and go too large, you can always solder it up and start over?

You can close it off and go back if you go too far. I can't remember what step up is. 1.16mm is pretty big. I guess I could go look at mine and see what size it is.
