I got a 460 in my boat and I'm having some trouble with the carb. It's a holley I believe a 750 with mechanical secondaries.  It won't start unless I use starting fluid but after that it idles fine.  If I give it throttle it stalls but if I do it slowly it runs fine.  Could it be the float level?

I have a few other carbs around I'll try switching to see if it fixes it. 

X2. With the engine off.... Or you might lose your eyebrows.
