Carter bbs problems

Tore it apart again today. I bought some gasket material and made my own airhorn gasket out of the better material. I then checked the gasket that goes between the main body and the base and found this. you can seeat about the 2 oclock position the gasket does not compeletly that square notch. The old gasket covered it. So I got out the exacto knife and hole punch and made a new one.
Re assembled and put back on. the problem is not as bad now. so I was able to actually keep it running long enough to spend time carefully squirting carb cleaner on the throttle shaft ends. When applying spray it goes from 900 rpms to about 1500.I guess thats where I'm getting all the extra air from, worn out shaft bores:BangHead:
