Ok folks new to the group and I'm hoping someone has the answer .
I have done the 300 distributor swap and it has been doing my box in and I'm ready to check myself into the nut house.
I have a 59 edsel with the two speed mile o matic and 223 motor
I used a duraspark for a 74 Econoline with the GM module
So after issues with the GM module going faulty and stalling in gear unless I had a very fast idle and a faulty distributor with to much free play in the mechanical advance I tried a different brand module and a replacement distributor it's certainly better nice slow idle and no stalling when in gear.and will rev nice
Now my latest issue has me stumped
The mechanical advance is actually retarding the timing and it's only when the vacuum starts to work that the mark's start to line back up.
With the timing set at 6'btdc it will retard past tdc to something like 4'atdc before it starts to come back as the vacuum takes over
Is this normal for this type of distributor
I currently have the vacuum line on the 1904 carb with the scv but I can drill and tap the inlet if required to go direct
Thanks for any suggestions
