What's on your bench now?

Was it the oem plug? What manufacturer? I’ve only encountered one loose plug on a chainsaw and only checked cuz it wasn’t running right.

 

Just commenting on your post, wasn't trying to point anything out...but I will now. There should be 2 electrodes, you were missing one.

 

I stand corrected. Thank you.

 

This mess of an Echo 750 that is getting new seals and fuel lines. Any one have suggestions of a gasket maker for the case halves that also serve as fuel and oil reservoirs? I've used motoseal for cylinders before but will it hold up sealing a fuel tank? The paper gasket is NLA and looks like a nightmare to try and cut.

 

I think Motoseal will work...I know Yamabond 4 will.
Edit: now that I think about it more, I seem to recall those sealers maybe don't like full on long term contact with gasoline.
The only thing I'm familiar with that actually states that it is for gasline is Seal All Automotive sealer...I've never used it for case sealer though.

Porters use motoseal and yamabond for base gasket deletes without issues.

 

Yeah it works great for that...its that gas tank detail that I'm not sure about...probably be fine, but I'd wait for one of these guys who has actually done it.

 

I've bought over 30 of these new style am Husqvarna pull handles

It took 4 years but I finally managed to tear all the rubber mounts
Johnmm on ope cuts down 262/288 spring mounts by 2 coils and runs them on his jonsereds husky 2 series equivalents
I'm going to try it
But the runner mounts don't bother me.

 

What brand plug?

 

NGK CMR 6H

 

Yup and it's called a ground strap just like you said...

 

Your model T might have had a "ground strap"...modern engines use plugs with side electrodes...look it up, you will not find a plug manufacturer reference a "ground strap" on a plug.
Straps are what you got beat with when you brought home yet another F from school.

 

Omg get a life...

 

Looks like you are both right.....

 

Right back atcha Skeet...you were the one that felt the need to comment/bring it up again.

 

Nope, they call it an electrode there too...just like I did in my original comment...which apparently was the secret pass word to pandoras box.

 

Side electrode, you
Ground strap, Skeeter

ground electrode, ngk....

Both ya have half of the nomenclature correct lol.

 

I think what’s interesting is the dissection above they call the the threads the corrugated ribs and explains why.

It’s a similar concept to bushing design on high and extra high voltage transformers. A resistor is built through the geometry.

In this loose plug you can see where the heat and the discharge was before it all Chat the bed

 

Maybe...was that illustration right from NGK? Cuz the one I posted was...and it said "side electrode" just like Honda teaches in tech school...not that I'm not totally over rolling around in the weeds with y'all over this...you can call it a lightning rod/strap/thingy for all I care.

 

To me its the flat thingy that the center thingy sends the blue to.

I looked up anatomy of a spark plug and the few I perused said it was the ground electrode. That said, it matters not to me. I knew what you meant and what skeeter meant.
