tree monkey 661 turning 15k?!?!?

[mdavlee]

I've never had my tach not read a non resistor plug. The resistor sometimes messes it up.

You mean "NON" resistor plug correct?

Yes. Sorry

Linkages on the three carbs I tried this morning WJ 48, 69 and Bing 49, throttle linkage and plate bound around half throttle.

I'm moving on to my chain.

It takes some bending to make it work.

I think Scott ask about the plug for a reason but not sure?

It doesn't matter what is done to it to make it do what it's doing.
A wj69 is all he did so how could a plug or anything else do it if all he changed was the carb?

Because it has a limited coil.
How could all these different people put a wj69 on one and not get a unlimited saw?

I have no doubt it's turning what the tach reads but it's not from just a wj69 like we are told,also if the coil is not limited what difference would a spark plug make?

Put a wj69 on one and screw the high shut and it will still 4 stroke or burble wfo no load,how can that be?

I'm not doubting that it's turning what it is but it's not just from a standard carb.
Everyone has gotten 14k from a carb but over time it will slow back down,go wow does that happen? The only thing left is the coil so how can it slow it down if you have control over the fuel and air?

In my opinion with a limited coil a sparking plugged could vary results with the interference, but the temp of a plug could also alter that too if you have a cold plug getting very hot like a glow plug.
Resistor plugs are and used for many items that to prevent interference with rf waves, fets/ micro switches. They won't make really any difference in the most simple basic magneto ignition systems unless other electronic items are near.
A non limited coil I'm sure won't care too much what plug your running cause it's gunna spark as the coil tells it too.

I don't have a 661 here, but I do have a theory.
Anyone have pics of the flywheel, and coil components available to look at?

661 left. Dont have flywheel pic on my phone.

They have different bolting patterns? Left is mtronic, right is standard carb coil?

Iam just glad y'all are getting this straightened out so in a few years when I can afford a clapped out one I'll knlw what to do.

I wonder if the gap between coil & flywheel changes anything (other than the timing).

We need to be thinking what is different about this saw from the others we work on.
Scott mentioned there are some parameters to be worked with, not against. So what is it that is truly different?

Flywheel has north and south poles. Let's start there.

Oo cried the exact same way when he couldn't figure out how to fix the HDA199s.

Right coil is from a standard carb 261.

Hi Tom!
Do you have any idea why these saws "appear" to be limited?

Ahh.
So the mtronics plug into the spade connectors? Or is there a different generator for that ?

I don't recall anyone showing interest in the port or ignition timing.

lol shhhhh i have a idea dan knows
