total advance ?

I've never been a big fan of vacuum adv either.......it seems like that part throttle cruising (like up a gradual hill) is exactly when it will like to ping.....drives me crazy. I always thought most cars I've dealt with liked more initial than the factory recommended anyway. Somewhere I saw an article on how they showed people how to limit the total mechanical advance by welding on some tabs on the weights and then slowly grinding them down......it's sort of a foggy memory of it. Anybody see that?
