Thread: Tri-Power Carbs build.

The .042 should be about right for the outboards, I'd try about .048s in the center to start.

Leave the accelerator pumps otherwise it will lean out way too much when you kick them in.

I normally set the float level just a bit lower than stock mostly because of the high summer temp and the 4500+ altitude I'm at. I would probably recommend that you set end carbs just a bit lower too. Under most conditions the fuel in them sits as the car will be running mostly on the center carb. The fuel inthese carbs has a lot more chance to heat soak and expand than the fuel in the center carb which is being used and replenished.

Mike, thanks for the tip on the idle screw adjuster tool. That's a real buggerboo on my F-380 Edelbrock intake on the 390. The three rochesters set so close together, I've been having a heck of time adjust the idle on the center carb. As soon as it gets warm the carbs are coming off and I'll do this simple adaption. I don't know why I didn't see this thread last fall, must be CRS.
