I have an ea81 I know for a fact the vacuum advance on my distributor is bad. The problem is I cannot find a suitable vacuum advance to replace my current one while i send it out for rebuild(have to get to work) So whats the DIFFERENCE BETWEEN ADVANCES FOR MANUAL AND AUTOMATIC? also is there a difference between advances with california emissions and without? They're no advances available for my 83 GL brat but I believe a 83 accord will work but the only one i can find is for an auto trans and the brat is 4 speedmanual and also my daily driver til my machinist finishes retrofitting my other subarus control arms
