Differences between Stihl 046/MS460

There's no need to drag my name into this...

Well you're the walking encyclopedia of stihl stuff.

Here's the Service Update from when Stihl went to the "Optimized" cylinder and piston for both 044 and 046. I believe this is the point where the D-shaped combustion chamber cylinder for 046 went away.

Amazingly enough, Stihl rated the newer cylinder and piston as having more power.

Thanks, according to that Service update it looks like they changed them 1-1-00. I found a 046 for sale that the person bought in 2000. It may be either one since it was so close to the change over.

Thanks for the info. Based on what I've gleaned, I'm gonna be on the lookout for an 046. I'm gonna wait for a "you suck" deal though.

You'll have to look long and hard to beat this sucky deal:

Looks like a fairly good saw. For the $350 its a good deal. check it out -tune it and cut with it.I modded the muffler on my 460 in order to let it breathe. There's more power & rpms waitin on you.

i have what i thought to be 046 piston here
looks to be 3/16ish pin height diff?
skirt length bout same

Might be an 048 piston, or 272, 281, 045 with the 52mm top end, and there are more but I can't think of them.

i will get a p/n later

064? Look up putting an 064 piston in an 046.

Different ( better) coil on some early coils

Yes, the 3 leg 1309 coil was the performance ones
also used on the 088

Here's my 046 Mag after a major restoration:

I later added a dual-port muffler. One mistake I made was to loan it to someone I thought was a friend. He never returned it. That's about the dumbest move I ever made in my life. This saw kicks butt.

The 1309 coil on the 088 is different than the 1309 coil on the 046. Curvature of the laminates on the 088 coil sweeps more because the 088 flywheel is much larger.

Jacob, what about the 1309 coil for 066mags?

For the Poly flywheel 066s it's a great coil. You have to be careful with that on the metal flywheel saws because it has an aggressive timing curve. I've got one on an early 066 I just built for myself and it rocks,
for a customer it might be an issue because it makes the motor run a little hotter and if someone is cutting in particularly hot conditions or milling, it could cause problems.

The 1309 also has a higher failure rate than other poly flywheel coils so that's a factor as well.
