Default Re: Too much timing?

I left my timing at 16, which is what I set it up a year or so ago. I plugged the vacuum port on the back of the carb and connected a rubber vacuum hose from the intake manifold to the distributor. The truck idles smooter when I hook the full vacuum up to the distributor, as the timing is further advanced.

Once I get above 800-1000 rpm, it seems to be the same as before.

I consistently run mine at 3K rpm and shift around 3,400 rpm when hauling a load. I still might install a gear splitter one of these days. Shifting from 3rd to 4th it drops 900-1000 rpm and when you're hauling a load, it struggles to maintain.
