Default Re: Vacuum Advance and why to use it on the street

My last smallblock acted the same as Erics when I attempted to use the VA. Locked out it ran wonderful. For the last several years I have not used any VA on my engines and most of my Dizzy's (dual points) don't even have a Va canister option. The MSD unit I have is the only one with a canister on it and it absolutely did not want to co-operate with me. Totally undrivable. If I knew it was beneficial and might prohibit a melt down and could make it work I would try it but so far it hasn't resulted in any issues not using it. I hammered it up and down the interstates from Alabama to Kentucky and the Smokey Mtns for hours at a time and never worried about a thing. Hook up the va and it won't pull a greasy string....
