hey everyone! got an interesting problem here.....i recently replaced my stock carb with an edelbrock 650cfm on my 350. it continuously drips gas into the intake for about 30 minutes after i shut off the car. after driving around town for a few minutes, the motor get flooded out. i have tried adjusting the damn thing to no avail. anyone had this experience before? also, i can't seem to get the timing set right either....i have a hi po cam and that's seems to be screwing it all up.....HELP!!!!! :confused:

Are the floats set-up correctly...thermal expansion of the fuel can cause just what you described. As for the timing wasn't it set before you did the carb? :confused:

Sounds like a problem with the float bowl... Try adjusting the float level... (those are the screws that are on top of the float bowls).. I'm no carb expert and really don't know how to adjust it right.. I'm sure that somebody here can give you detailed instructions...

I am no experience mech. but this what happened to me when i took out the float screw and clean it up and a very very small dirt got in where the screw is and I could not adjust it anymore and it also flooded the engine,took out hte bowl cleaned to fit it. I hope this is help. :)

yeah the timing was set before, however the cap wasn't tightened down and while putting on chrome valve covers mysteriously everything went haywire.....funny how that could happen, huh? haha

#1 Go to the tech section in this forum for timing your engine they have good advice to get you going the right direction.
#2 Make sure you have no vac leaks when setting up the carb!
#3 Get the floats set-up
#4 Do Idle circuits
#5 Insure the secondary circuits are done....this takes a bit more fiddling.
#6 Take your time and HAVE FUN

Ultimate fix: Buy EFI :yesnod:

I've had years of trouble free - maintenance free - use from my Edelbrock carb.
I can't say that about the Holleys I've owned.

You may have a piece of crud that entered the fuel line during install.
This crud can get caught in the float and force it to stay open.
If adjusting it doesn't help, you may need to dissasemble and clean her out.

ps - an inline fuel filter close to the inlet will help with future fuel line work
that is done between carb and tank.
