your pics look like you're running a holley 670 avenger (4150). I see nothing in the holley specs that shows this is anything beyond a stock 4150. Before you go scratching your head, what are the symptoms you're experiencing with the flooding? Is in on acceleration, deceleration, WOT, during turns, etc? There's lots of options from whistles, to jet extensions, to off-road (spring-loaded) needles and seats, different floats, etc. most of these are fairly inexpensive. I'm sure someone on this forum can throw some advise at ya.

actually its a 750 DP http://www.summitracing.com/parts/hly-0-76750bk

the issue im having its flooding the motor, when the epump goes on (engine off) I can see the jets leaking which floods the motor. I tried re-adjusting the floatbowl but issue persists.

Take the bowls off and clean the needles and seats out with some brake cleaner and a little compressed air.

while you're at it, install holley part 6-513, spring loaded needle/seat (off-road) in both bowls.

thanks for the recommendation,

@72BBSwinger
decided to take the carb off and open both bowls, found debris which was making the needle stuck. So I cleaned it re-assembled and now shes good to go! thanks for the tip.

Stuff happens.

Oh hey ignore that.. I just read your post about debris in the needles.

Anyway, now someone else knows!

Check the fuel pressure. It shoudlnt exceed 7psi on a carbureted engine. May need to make sure your regulator is working properly by installing a fuel rail to the carb front/rear with a gauge.

Fuel pressure too high will over-power the needles and just start dumping fuel into the engine.

Ive seen it happen a hundred times!

hahah thanks for the tip! one of the reasons i love this forum!

i have been checking fuel pressure so its good. I do have a fuel rail with gauge but I need to replace the summit liquid gauge though, the thing crapped out. any recommendations?
