"I have just put a 454 into a 29 ft bayliner. We have the engine running and tomorrow I will be setting the timing properly, but I need a good starting point for the jets in the carb. It is a Holley marine model 4160. It came from a big block Ford. The engine currently belches out black smoke when you start it, or goose the throttle. I know I will have to take it to the lake to really set it up correctly, but I am looking for a good starting point. Anyone have any ideas?"

"Unless they have been changed, the stock jets should work fine. On that black smoke; is the choke opening all the way? If so, the accelerator pump might be a bit too aggresive (rare). Holley sells a tuning kit to adjust the amount of squirt.

If you backfired it at all replace the power valves. They will be dumping fuel if they are popped.
