Default Re: Ignition advance

Yeah, I bought one so I know how they are adjusted but I have not installed it yet. I wrongly assumed that the adjustment had something to do with the sensitivity of the diaphragm. You are stating that the adjustment changes the length of throw to impact the amount of advance available. I know how mechanical and vacuum advances work in distributors but I did not know what the vacuum adjustment actually changed.
