It takes VERY little to get 6°. I set it with a degree wheel.
What I saw was very impressive in the videos. I request that you post another thread and pics of the timing advance method with pics and the mod you did to the muffler. I wonder if anyone else who has already posted would like the same?:msp_wink:
Pics of a muffler mod are in the thread I did in 2011. There's a link on the previous page.
To adjust the timing, all I do is to thin the key that's cast into the flywheel. You need to thin one side so that the flywheel can be rotated counter clockwise 6° while the crank stays stationary. Then, simply lock the flywheel down by tightening the nut down.
Brad,
I second the motion for pictures on the timing advance.
I've seen your muffler pictures but I too would like to see a couple pics of how you do the timing advance. I completely understand the concept -- just not sure how to do it accurately? How do you get a good reference off the shaft as small as it is? If you have the degree wheel under the flywheel what do you attach it to? If you have it above the flywheel you have to take it off each time you want to file a little more off so how do you get it realigned correctly each time?
As they say, a picture's worth a thousand words, and here I think a couple shots of your process for doing the timing advance would be very helpful.
Thanks.

P.S. Don't you mean 6° counterclockwise?
