Engine dies when warm

Did you set the timing with the vacuum advance disconnected and capped off?
Sorry for the late response but I havnt been able to work on my car until today. I sprayed carb cleaner around the manifold and brake booster and did not notice a difference in rpm, is there a better way to find a possible vacuum leak?

Also I tried connecting the vacuum advance to manifold vacuum and the problem still occurs.

I did not set the timing with a light because the tab on the timing cover has broken off. I found TDC and got it as close as I can. While the car is in park I can mess with the throttle and bring it up to any rpm without a problem. Wouldn’t incorrect timing cause it to die when I do this no matter what gear it’s in? Like I said I’m still new to all this.
