My Holley 650 double Pumper has stranded me twice due to the secondaries flooding and fouling out my plugs. The first time it happened I took the needle and seats out and there was part of a green gasket lodged in it. So I just rapleced the needle and seat with a new one. Then last night it stalled out on me driving home from work and I have the clear sight pins so I noticed the front was fine but the secondaries were flooded. I eventually got running after calling my wife to bring the tools. The needle looked clean but I put another new one in and adjusted the float lower then normal to see what would happen and to get me home. What's going with this, how does the float keep flooding on me? How do I tell what size needle and seets I have? I just took them out of the new rebuild kit I have and stuck them in the car. Thanks, Erik

Are you sure there isn't a tiny hole in your float?

Make sure there isn't anything in there. Mine was so full once, I couldn't even hear the liquid sloshing around in there.

I agree, check the float. I was stranded once b/c of this.

Take it off the fuel bowl and feel how much it weighs. If you still don't think it's the float, tie a weight around it and submerge it in a bowl of water overnight and then check again.

Also I have seen folks install needle and seats and not lubed up the o-ring. THAT is what gets caught in the seat or allows fuel to flood your bowls ,provided that the float is not "heavy"

Sometimes when they stick due to the needle and seat being at fault, I'll tap on the bowl with a hammer, wrench, etc., and sometimes it come up and get you home.

My friends 650 has done that twice and I've had to hit the top of the carb to keep his car running again. There has been around 6 months in between so I kinda discard the fuel float in his case. He uses his car everyday so we haven't got a chance to install a new needle, I just recomended him to pour some fuel additive on the gas tank every now and then hoping it will help him on this. Just my 2¢

It has happened to me only twice and it has been about 8 months apart. Do you think it was just a fluke? Why would it only do it on the secondary side both times? Does anybody how to tell what size needle and seats you have, are they marked? I really didn't see any markings but I know the new one I put in had a larger diameter plunger thing on the bottom of it.

What's the shape of the fuel filter and fuel line going to the carb? Sounds like you are getting a little bit of dirt from somewhere that keeps clogging things up.

I don't really know that there are different sizes of needles & seats.

You might want to get new lines to the carb, new filter, and have the carb dipped somewhere as a way to start over.
