Mastermind Meets The MS661 C-M

[Mastermind]

I just ran this 661 VS a 066 I just ported with a 461 coil........the 066 was just one second behind.

Hmm.....

 

[mdavlee]

I got a 46 and 66 laying around if you need it.

Have you put a 461 in that log yet ? with 28 inch bar it should be hanging with them pretty close ,till the 36 goes on ..............should change things a bit

Have you seen the thread of turning a 461 ignition coil to unlimited? Might be a possibility for the 661 coil?

How come the 461 coil on the 066? Just curious ya know .

WOW, I had to edit. A post from a whole different thread just showed up here.....

this wonderful site is blocking your link for me

 

[Stihlman441]

Yep cant see it as well.

Search
MS 461 "De-Limiting" the Speed Limiter
on google. The topic is on the FF forum so censored

 

[Mastermind]

I was banned from FF.....

**** that place.

Durand, I just wanted to try the 461 coil on it. It limits RPM to 13,500, and has a nice advance curve.

 

[komatsuvarna]

Gotchya! I knew you had a reason.

 

[Stihlman441]

Thanks for that an easy way to unlimit a 461 coil.

 

[Mastermind]

I can't read it........tell us about it.

Ok, credits go to joe_indi on FF, original poster. But I'll take over the content:

The speed limiter on the MS461 can be a nuisance at times.
#. Your old tach will not work for carb tune-ups
#. If you are used to setting your carb to any rpm above 13,500, its difficult.

In the MS461 the rpm sensing is done by the 3rd pole of the ignition module, which differentiates the 461(ignition module) from the 2 pole unit on the 460.

So, I just cut off the 3rd pole! Okay, not chopped off completely, but trimmed off enough so that this pole will not pick up any working magnetic impulses from the flywheel
And it works.

I held the pole compressed with a pair of pliers that had wet cotton waste on the jaws.This prevented the iron plates from transferring heat onto the coil inside while I used a hand held cutter.
Heat transfer will sometimes cause the copper winding to snap from expansion.

I didn't link the site because I assumed it to be not appropriate. But everyone can google it and look up the original site and info without any membership.

But it might help someone here.

It's a nice find! Thanks for sharing!
I don't know if they agree with what I've done by copying the content, here or on FF. But I'll take the chance considering it is public content on the web (ofc all the credits go to the poster), and saw specific, not forum specific.

Your welcome. But I see it as a more delicate matter. Every site has it's right of existence and publishing info off other sites without approval is something I wouldn't do. Giving a hint at where to find the info is ok.

But I am not the judge here, others will do that job!

Awesome info!!!!

I wouldn't normally do it, but considering the original link gets censored (and Randy can't see it and it could be important for this build). My post is just a copy with credits to the original source so it should be enough info, even in an official paper. And I didn't notice any specific copyright info on FF. Just trying to make it easier for everyone. Content can be removed if necessary but the whole forum is full with info copied from other sites without source, maybe not intentional but that's not the point. We'll see what the judges say
