starting is getting harder

and i am not talking about me in the morning...

just switched up the 009 with compufire for a 019 with points and the engine dies when you let go the trottle. it was running ok before, but i was said that a 019 was such a nice distributor for a smaller engine, so i gave it a try. i set the advance at 10° and it starts ok, but it won't run on idle. i haven't been able to run the car on the street yet, so i can't say there is a big difference, but i want it to idle like before. what am i missing here? i have installed new points and a new condensor.

any ideas of what might be the problem?
