Antiseieze Norm swares by it i do as well. A little dab on the threads to plug works great. Do not want it on the electrode. A little bit goes a long ways. As Norm said pretty soon you've got the sh^*** all over you!

I have a big tub full of anti-seize lubricant!!! Stuff is made by permatex, and yes, just a little will do. I put the stuff on my lawn mower muffler threads and man it makes a lot of white smoke!!!

You could always use a thread chaser or tap to remove the carbon build up from the head(engine top). carb cleaner can help too.

When we speak of gap, is that in inches?

Mistright1, I am down to the plug the wire or did something go wrong with the gas mixture, while just sitting there, other than the fact the weather has changed a little and I am at sea level, I am running with the stock carb accelerator setting, that I have not changed, but am willing to.

I am still getting loss of power not so much bogging down, but the power isn't where it was. It is like it is missing, or not firing exactly right, this occurs only when in motion and accelerating. Kind of a rough ride like you are riding the RR ties, but not actually that drastic.

Can you give me a gap spec. I should be using ?

The last tank which was I believe my fourth gallon was 30-1 per Kings,

I used Valvoline 2 Cy. Multi-purpose.

Gap @ .020-.024"

Sounds like you are running too rich, try the needle clip up a notch or two. (second from top or top notch).

Hi
I installed a B6HS spark plug yesterday night
Stock plug was LD Z8C
Both were gapped at 0.6 mm (0.025'')
First impression: climbed a hill easier than before (needed some pedaling help before)
Today, the engine needed more time to get hot
Then I had to adjust the idle screw more than a full turn to keep the engine running
Seems to run better at high revs, but that could be sujective
Peace
PD Insulator nose length was shorter in stock plug, but b6hs seems cooler (???)
