tree monkey 661 turning 15k?!?!?

[tree monkey]

I've seen and ran other 661's with the WJ 69 and they wouldn't turn that rpm, regardless of how much it was leaned out.

well now you have.lol

@Redbull661 you painting scotts shop also ?

 

[tree monkey]

we are testing to find the limitations of the coil. it is certainly not rpm. there are some "fixed" parameters you need to learn to work with, not against

 

[tree monkey]

Resetting ahead of time?
just curious, not trying to stir the pot

no, we don't ever reset the coil. there's no need to.

This post says a lot.


What your sayin is, if you just swap to a regular carb. You ain't gunna be able to turn serious rpm

all we done was change the carb on the woods port saw you have all seen vids of. changed nothing but put a wj69 on it.

They aint buyin it Scott!! Lol!!

 

[tree monkey]

well it's the truth

So then these coils are not limited? But it limits itself with fuel with the mtronic carb?

yes, been saying that for a long time

kinda like what we talked dan about the flywheel is limiting the voltage going to the mtronic carb

 

[dall]

the fuel solenoid can only open so far with the voltage produced by the flywheel /coil

 

[tree monkey]

the system can and will feed more fuel to the engine then it can burn. that's been tested

So is the default on the solenoid closed? It would need to open more to limit the saw with fuel. Not less...
It could very well just be programmed as a governor at 13.5 or whatever. If it turns faster than the programming allows it opens the solenoid fully to limit the saw.

I've had a carb on one several times and could screw the high shut and not get anymore rpm and so has several other people.

That's what I was thinking Scott. Makes sense

Yes, but lots of fuel doesn't make rpm

 

[jmssaws]

It's not as simple as putting a wj69 on it or everyone that's tried it wouldn't say the same thing.

Yes, but lots of fuel doesn't make rpm

Which is why the mtronic needs to be defeated. Right?

It's easy to defeat mtronic, but a fully unlimited 661 isn't as easy
