Project Stumpbroke MS361

[nmurph]

361 MM = 30
361 Ported = 27
460 = 27

I just eyeballed it with the timer on the player.

So, it was a 11% gain with the porting.

Pretty much the same times I got.

A stock muffler :bang: would have made for a better wow factor in the first vid, but it is what it is.

Nice work, the 361 is a nice saw ,thats one model i dont have yet

Hey Stumpy,

Where does that passage terminate for the impulse line? Just a few mm into the body of the carb? Also, how did you go about swaping choke shafts? Simple unbolt one and bolt up the other?

Thanks, great job and a good read.

Yes it's just a few mm into the body. you have to drill in two places to get them to connect.

The hole on the upper right hand side needs to be drilled.

Then drill the passage that the screwdriver is pointing too until they connect.

The choke shaft does have to be cut (widened) to accept the larger butterfly of the bigger carb. other than that it's just a matter of swaping them out.

Thanks.
I'm a Husqvarna man but, he 361 has become my favorite all around Stihl. The 261 is a close second. There, I said it.:msp_sneaky:

I may be wrong but the 361 jug sure has a lot of similarities to a husky 372,have you got to do 461 yet ?

All I want to know is why they always put the stunningly beautiful models in these shoots? Why can't they have a regular looking "joe" cuttin cookies.... :msp_smile::msp_smile::msp_smile::msp_smile:

Nice work Stumpy....as always.

I have heard it repeated that a Husky engineer stole the plans from a saw (357?) and went to work for Stihl.

IMPRESSIVE! Nice editing on the video too.
I thought long and hard about porting a 361. I decided that a 440 is barely more weight and with a mm, quite a bit stronger. Anyone selling a 440?
Did you swap oilers? My 361s were very stingy with oil.

The 361 is the only Stihl I've ever wanted to own...

But that thought quickly went away the first time I ran a 562xp...

They do resemble the quadport huskys but Have much smaller transfer runners.
No, I've not had a chance to port a 461 yet

No the oiler is stock. The owner will be running either an 18 or 20 inch bar and it does fine with those lengths.

Nice work Chad

Just sayin,,,

Stumpy-- what did the compression run after porting?-- will it need an elasto start handle if run without the compression release?

It's over 200psi. Elastostart would be nice but it's not that hard on the hands. Just gotta make sure you mean it when pulling the handle.:msp_wink:

 

[F.W.P.T]

Wondering how fuel consumption compares? I've heard the ms460 is a thirsty one but how about the 361 after it's done up like that lil beast??????

 

[flyinlow]

Stumpy-- did you take a tach reading while the 361 was buried in the oak?

Yes, it was pulling 10,000 -10,200 in that vid. The 460 was pulling around 9,000.

BTW, Stumpy, don't be a stranger. It's good to see you around.
