Sparks out of the Carburetor

I recently noticed my problem with the bogging out of the carb. I kept the hood open and the air cleaner off and watched the carburetor, to see either sparks or fuel fly out from under the butterfly choke. what is going on?

What kind of car/engine/carb setup are we talking about.

W/o those kinds of things all you'll get is wild guesses or no response at all.

Wild guess #1. The car could be backfiring due to bad timing causing the burning fuel to be coming back up the carb.

Fill in the blanks and you'll get a better answer.

SPARKS

Your choke should be closed with the engine cold, push the accel pedal and the choke should close with a tad bit of tension on it, after you start it up, the butterfly should open about 1/4 inch initially, and continue to open as the engine warms up, and should be straight up when the engines warm. Is this driving or sitting still? It's fuel

It is on a 340 mopar engine. edelbrock 600cfm with electric choke.

I timed car to make sure, timing is set.

when i went out to the carb when it was cold, the butterfly flap was open, as it should be. however, when i added about 1/4 throttle with the key off, it did not shut itslef, which it is supposed to. edelbrock tech support told me that if my black electric choke cap wasn't extremely hot while the key was on, not engine running, it could cause something such as that. my black cap never got hot, so I don't know if that can be it.

Your 1st problem is that the choke isn't closing, if all the linkage is good,loosen the screws turn the black cover so the butterfly is closing cold, Sounds like the linkage isn't hooked up correctly, get the choke to close and then go from there!The electric heats up the thermostatic spring in the black housing to "open" the butterfly" choke" as the engine warms up. You don't need the key on to check the choke cold, leave it off.
