I know this seems redundant and a pain, but absolutely needs to be done right before making changes. First, be sure your ignition timing is correctly set (the primary word there is correctly
). Anything done half-assed here will affect everything else as you go. Don't short-cut.
Then, follow a good basic setup guide, like this one
. Be sure to read the link about vacuum gauges. When you've done that, read some other tips on basic adjustments here
. Just gloss the whole thing a couple times to get the high-points and apply them.
Now - how does it run? Pretty dang good I'll bet. Where does it need more tuning? By this point the answers should be pretty obvious and fairly minor. Also, don't assume you need more when you need less or the same for a different period of time. For example, a stumble with a large-port and open manifold may not need more accelerator pump fuel flow, but rather the same flow over a longer period of time to let the engine 'catch-up' before the extra fuel is gone.
Enjoy the process, and post how it changes after following the basic tuning setup, and what you think it needs after that.
