Vaccum advance/Lucas Dizzy
Before I start my search for a new replacement distributer, how do you know if the vaccum advance is working properly? I've tried blowing air through the line to the distributer. Even if you suck the air through the line, no movement of air either way. (**Note: Vehicle in reference has 2.5L engine w/ 2-barral Weber carb.)
1.) If the vaccum advance is shot, is it something that can be replaced without replacing the entire distributer?
2.) I have a Jacobs Ignition / Petronix Igniter - obviously there are no more points in the dizzy, so with that said...does the vaccum advance even come into play if I currently have the petronix setup?
3.) Should I need to get a new distributer, is it possible to still find a new Lucas distributer (part# 42618B 45D4)? Wasn't even sure if they still made them.
thanks!
