ignition advance rotor identification
I was wondering, I just got a factory pro advancer that is 6 degrees and it has a 6 stamped on it. now I assume that is to tell you it is a 6 degree advance, right? the one I was trying to pull off (anyway to do that WITHOUT an impact wrench??) has an 8 stamped on it... am I downgrading, or does the 8 not really mean anything?? and how have you guys gotten these things off?? thanks!

I don't believe they make a 8 degree advancer? I have a 6 degree on my Hurricane. Is the one you took off made a little thicker metal if it is its a stock one?

if I line up the 7 teeth (the LARGE ones that look like teeth on a sprocket) the indent that lines up the the advancer on the mount so it only fits one way) the indent is at about 4:00 on the one I took off and about 5:00 on the new one. is that the direction it would be to advance the timing? I am going to have to take them off and take a pic side by side I think. the stock one have any numbers stamped on them?? thanks a lot!!

I will see today if I can find my old stock advancer and see what numbers may or may not be on it.

Stock advancer
I found my stock advancer and yes it has a number 8 stamped on the top and that the only number or marking on it.
I can not find my factory manual at the moment to find out what the stock static timing is? The number 8 could be +8 degrees and the after market ones are + whatever stock is so maybe its at 14 degrees total with the plus 6 (if stock is 8+6=14) could be that way but maybe not?
The extra timing helps thottle responds but I don't think it would help top end power. also advancing helps a stock engine but a highly modified one may need less advance that stock.
