Ok guys I got a problem with my carb.. It constantly will flood the engine thus causing the spark plugs to foul and me be sad.. I've noticed that there is pressure in my fuel lines.. A lot more then there should be I think.. I'll leave after driving my car and the fuel filter will be nearly empty. I come back a couple hours later and the fuel filter will be completely full with no air bubbles at all.. Also I need someone if they could to take a picture at how their gas tank vents.. I'm wondering if it has something to do with my problem..

bad venting will cause a vacuum in the tank
resulting in No fuel to the engine...
 
or a partial vacuum resulting in the carby running out of fuel..
 
the likely cause is the needle and seat where the fuel flows thru
into the carby bowl...
if the needle and seat don't seal when the float is at its highest level
then fuel overflows into the inlet manifold...
 
Firstly, check Your engine oil to see if it smells like gas...
if it does.. change the oil... before running the engine..
 
I don't usually take any notice of the fuel filter..
as I've seen many with virtually no fuel in them and thats normal...
 
it also depends on where Your fuel filter is located..
 
If your car drove OK before and this has just happened then I would suspect the needle and seat in the top of the carby...
 
I have an electric fuel pump under the tank
and i have a fuel pressure gauge in the engine compartment..
and I have pressure in My fuel lines all the time...
even after a few days of not being used...
so, My needle and seat is cutting off and is holding pressure in the fuel lines..
 
I find its best to locate the fuel filter where it cannot be seen... lol
otherwise it will drive You to drink.. lol
 
I hope this helps You... somehow...
 
if You take the top off the carburetor,
wait until the gas has vaporised..
and blow into the pipe where the fuel goes in...
and then press the needle back up into the seat and You shouldn't be able to blow any more...
do this a few times to dislodge anything in there...
if it seems to work ok
put the top back on
and keep Your fingers crossed...
 
cheers

Now I've gotten to stop flooding but not it pops everyonce in a while while i'm sitting at stop lights.. I think its going lean but the thing drives awsome all the time besides sitting at lights.. So does that sound like its leaning out?
