Glad youze guys got that all figured out.

One thing that bothers me is the term advance timing.

Unless someone has figure out a way to strap Miss Cleo onto one of them modules it is against all laws of physics to have an action before it happens.

What they do is retard the timing and when advance is needed the timing is retarded less all the way up to 1;1.

Any questions class?

Umm - the spark happens in advance of the piston reaching TDC. Care to explain how this violates the laws of physics?

Of course it assumes that the piston actually will reach TDC after the spark happens, and maybe it won't - I dunno, I never ran a Sachs.
 
Well since there is no way to be rid of you, at least be useful. Get over in the Christmas giving thread and give away some of those saw parts you've been hoarding. :laugh:

So when advance is needed, it retards it less, which advances it more? Sort of like when you advance timing?

OK can I just bring them over? Set up the chess board.
 
You play chess do ya?

It's the game of Kings.

OK MR. Wizard,

let us make some elementary assumptions,

1. we are talking chainsaws

2. the current is generated by rotating magnets

3. the magnets don't move (centrafugally they are static and molded into the casting)

4. the flywheel is mounted to the crankshaft

5. saws don't have onboard current storage (battery) OK some old macs did

6 an event can not happen before it happens.




Sure with some fancy programming and an onboard power supply you could conceivably make a spark happen before the event of the magnets passing the pick-up.

I don't see it happening.

Go back and read my post again, you can NOT have an event before it happens.

Clear as mud?

Lol - I know exactly how the system works. The magnets and coil are typically placed so that the spark happens a certain number of degrees before TDC. Therefore if the spark happens when the magnets pass the coil it will happen before TDC, no? This is wizardry?

In reality this is a cyclical system. I could place the coil magnet relationship anywhere relative to TDC (including after TDC), ignore, say, the first 2 revolutions of the crank, and still have the spark happen "before" TDC (but on subsequent revolutions). This stuff isn't really that complicated, and no laws of physics are violated.
 
Just terminology, but when people say "it advances the timing" ????????????????????????


Oh forget it I forgot who I was jawin' with.

The sentence is obviously not complete unless one is told in comparison to what. You could assume it means it gets advanced relative to the present time, but you would need flux capacitors for that. This is just a spinning magnet on a crankshaft.
 
more than likely the 661 will be set to run way to lean and blow up like the rash of 660s we had a few years ago that kept blowing up right of the box with almost no hours on them. like everyone says man it sure cut great for that last minute or so the chitty chitty clunk.

Are you an engineer or a lawyer?

Perhaps a Quantum Physicist?

**** I could have been one of them, just grab my bag O' weed and sit around stating it could be this or it could be that.

We are talking 661 here, not something that could be and I will stand by my statement that the system does not advance the timing past the real world event.

That is what I'm stating in a nutshell the system retards the timing and can advance the spark no further than the event of the pickup signal.

Get it, got it?,,,,,,,,,,GOOD!
