If it runs best at 12* then leave it there. As long as it doesn't ping it should be fine. Most any engine will not run well at 0*, there has to be some lead time to get the fuel burning.
Yes i just wanted to make sure. I new it would be advanced just wasn't sure how much with the mild cam it seems to idle fairly well but until i get it on the street for a test drive then i can do some final tweaking.
I tried advancing it to like 20 and it seem to idle better around 12 or 15
I also will be hooking up my tack tomorrow so i can check it at other rpms as kimmer said
thanks for all the help guys this place is a huge learning curve and very informative 8)
