Mastermind Meets The MS400 C-M

[Mastermind]

I hate using my phone to do these threads....I lose pictures, have trouble seeing the thumbnails, and I can't type worth a damn on it.....but

We're gonna compare the MS400 to the MS362 anyhow.



The 400 is built on the same chassis as the 362...but rather than a 59cc unit, it is a 67cc machine.

In for the plastic handlebars.

 

[Mastermind]

This is the 362 jug and intake.



And this is the 400.



The difference is at the strato ports. They are a little bigger on the 400.

 

[Mastermind]

The carb side....362.



400



Yes....the carb is bigger on the 400, but the strato butterfly is the same.

 

[Mastermind]

The 362 carb....



The 400 carb.

Big difference in the venturi.

 

[Mastermind]

Ignition modules.

400



362



Everything is the same except the last group of numbers.

 

[Mastermind]

362 jug....



400....

 

[Mastermind]

Gotta help Glenda in the kitchen. BRB

 

[Mastermind]

Backing up a bit.

I've heard a few people say working on a 362 is a pain in the ass. Not at all.....just gotta take it apart, and assemble it correctly. The 400 is the same....

 

[Mastermind]

Like I said....pictures all out of order and crap.

Build dates and stuff.

 

[Mastermind]

Dry weights.

 

[Mastermind]

362....



400...

 

[Mastermind]

Different mufflers too....but only the outlet size is different.

400



362

 

[Mastermind]

Another difference here.

The 400 has a heat shield, the 362 doesn't.

 

[Mastermind]

Absolutely no difference looking at the front of the saws.

 

[Mastermind]

Crankcases.

400....

Also notice the magnesium piston.




The 362....

 

[Mastermind]

Ok....now the slugs. LOL

400...



362...

 

[Mastermind]

The MS400 is a 50mm bore, the 362 is 47mm.

A 3mm larger piston made from aluminum would have required a different crankshaft with heavier counterweights I suppose.

By making the piston from magnesium, they were able to use the same crankshaft.

That's how they built a 67cc saw that is lighter than many 50cc units.

Genius.

 

[redline4]

So if a guy had a roached 362, could a guy swap slug, jug, intake and carb right on it? It looks that way to me.

 

[Mastermind]

Now, for the cylinders. I can see the 400 being a game changer for Stihl. The front entrance for the transfer ports is big enough to allow some serious power.

400...



362...
