Mastermind Meets The MS661 Again

[treeslayer2003]

i am of the oppinion that any sthil that don't start in two pulls has a problem.

 

[coltont]

I concur. It's just amazing how the dammed thing just wakes up all of the sudden once it's warmed up

 

[Moparmyway]

Any pics Randy

Sure.......

OK, cards against the chest I see .............
Hows about the latest & greatest in a video ?

Not really Danny......I never want to build saw engines that aren't able to work for a living. A chainsaw is a tool, and should able to be used all day, everyday, no matter the temperature, or enviroment.

Next level refers to the amount of time I put in to learning about each model to be sure I'm getting good solid, repeatable gains.

I like to think we take porting chainsaws to The Next Level.



No.......I mark em all......if I remember to.

When do we see the new stickers?? And serial numbered cylinders? I want #100000.

Modded....

Definitely something wrong with our 660 then.... our backpack blower yes. That thing is a champ.

 

[MustangMike]

That's almost as fast as the 044!

 

[komatsuvarna]

That 661 even sounds way healthier than a 660.

...and its carrying the mail to boot!

 

[gunnusmc03]

That 661 is a beast

Will all 661's be ported the same as this one now Randy now you have found the sweet spot

 

[Mastermind]

It depends on what the owner wants. If they are ok with the Devcon in the intake....then, yes, this is what I will do on them all.

There's just no way to get these gains without shortening the intake duration.

l don't see a problem with Devcon, its one of those things that only work well if correct preperation is done and from the pics Randy has posted on this l think he is utilising/installing it very well. You gotta do what yo gotta do with performance and l think its great how his approach evolves as tue market releases new design and tech. He has always had the 'make what is already there better' philosophy rather than to 'reinvent the wheel' so to speak. These 661's are great build saws, l want one!

 

[Mastermind]

There are a few other saws that have too much intake timing.......

This opens up a world of possibilities to me.

I can hear your brain ticking over from here Randy

Can you smell smoke? That's the rust burning off the gears.

Reminds I need to get off my butt and get the jug off mine and send it down to you to cut the chamber and base.
