661 R&D

[Chainsaw Jim]

The 661 8 pin runs are about 8 seconds and were neck and neck with the 056 hybrid. 066 was about 2 seconds slower.

Wow

 

[RI Chevy]

How are you liking that Mtronic?

 

[jmssaws]

661 is 9.1
066 9.2 9.1
056 8.3 9.7

 

[RI Chevy]

That sounds about right.
I wouldn't kick any of them out of my arsenal. Lol.
They all ran great!

 

[Chainsaw Jim]

The youtube counter doesn't go down to tenths so I'm forced to use words like "about" and "almost". Lol

Is this your personal hotrod 066 ?

Yes it's mine.
Just a work saw like the rest.
I didn't think the 661 ran as good as it does.
Got a 28" on and a wj35

Lots smoother.

You have the holly dominator carb on that saw ? or was that another one ?

066 has a wj35 stock carb and so does the 056 saw

 

[jmssaws]

That right. Feels slow but it aint

And you still have potential gains to go still with the 661 ?I like the saw ,but not the elec carb stuff ,be cool to see if can get gains with carb change .

It certainly sounds better with a regular carb. Gonna try it in a minute.
Lot more snappy

I can certainly beat it I'd think.
It's only in the high 16o's for compression and has pretty short bd.


I'll check rpm
It has no upgrades,coil and boot are old school and the muffler is almost stock with a tiny screen

 

[jmssaws]

Only thing I changed is put a standard carb on and it gained but the muffler was broke on my 066 the first time I ran them
It's not broke here and I think it gets the 661 by a nose

 

[RI Chevy]

Sounds good. Does it feel stronger with the regular carb on it versus the Mtronic?

Definitely stronger with a standard carb.
Gained some needed rpm

 

[RI Chevy]

That's what it sounded like to me as well.

 

[jmssaws]

Looks like I need to back the timing off a touch.
