Engine Dies when timing is advanced

[Josh Bostic]

Hello, my neighbor just purchased a 1929 Tudor and has been working on it for the past few months, we have worked out all the typical bugs and getting ready to drive this fall. The most recent that has us both confused. After dealing with a very worn out distributor he has replaced it with a brand new one that included everything (points condenser plates, body, shaft) install and timed the car ran great for several test runs until today. Now it dies almost instantly once you advance the timing about 3/4 down, if the timing is retarded all the way up it runs fine. Any ideas or suggestions? Thanks!
