60 Chevrolet pickup 235 not running right

[Original60Apache]

Hi everyone, I recently finished the restoration part of the 60 and the 235 that is in it doesn't run right. It's a '55 235 with a one barrel Rochester. We had it running fairly well but it had a slight miss once every 4-5 seconds. So we decided to swap plugs since they looked close to fouled, and we took a little sandpaper to the distributor points. We put it back together and sometimes it would start and sometimes not. Once running it ran rough. Then after adjusting the points to .019. After that we fired it back up. It idled well but once we brought up the rpms, it would act like it had some rev limiter at somewhere between 2000-2500 rpms. We did notice there was no vacuum advance working and it seems to act like the timing is off when it revs up.

Thanks

Nate
