Dripping Carbs
I have a pair of Weber 45 DCOEs on my pinto, i bought them with the engine so they are all set up for it. I was turning the engine over yesterday
trying to get it to start. After i realised there was no spark i was having a look at the dizzy when i noticed fuel dripping from the trumpets of one
of the carbs. I gave the throttle a bit of a squeeze when starting to try and get it to fire so this would have put more fuel into them, but i noticed
fuel was still dripping into the carb afterwards and took a while to stop. This was only happening with one of the carbs.
I am using a facet fuel pump with a filter king regulator set to 2 psi.
Anyone have any ideas why this is happening, just seems a bit dangerous to me!!
Thanks

Accelerator Pump?
Certainly this is the case on the 32/26 DGAV that I'm running. Not particularly dangerous because you only really press the throttle when the
engines running and being a downdraft it never drips out.
Not sure if the DCOEs have accel pump...
Cheers

First off a Filter King like any other regulator can only work properly when fuel is actually flowing, the slightest bit of wear and it cannot
regulate the pressure when the fuel pump is on but the engine is not running. If you have a high pressure pump best to get it off and fit a lower
pump intended for carbs.
Of course it goes without saying to check the float level heights and condition of the needle valves.

Oh forgot to say also make sure the accelerator punp nozzles are facing/squirting towards the engine -- on the DCOE they can be fitted the wrong
way round

The carbs worked fine on the engine before, it maybe just that the engine needs to be running properly, the engine just turning over is probs not
enough to suck all the fuel in, just wondered why they kept on dripping afterwards and if it would carry on when i get the engine running properly.
Just need to figure out why the ignition system is working on this engine now!
Thanks

I suspect you are mixing up cause and effect the carbs are flooding because the float chamber is over filling --- hazardous so say the least !
