It is still dumping to much gas in the cylinders, fouling my plugs and backfiring, these carbs I just bought are extra clean, they look brand new, and it is still doing the same thing as my old carbs, any ideas, and not smart remarks please

Both the above are possible. You should also check the jetting on these carbs ... if the jets are too large (or not installed correctly) they will allow too much fuel into the mixture ... sort of like running on "choke" all the time. Not good.
So, tap the carbs (stuck floats), adjust the carbs (left then right then four together), or rejet the carbs ,,, and that's pretty much in order of difficulty, too.
Good luck.

Always give year, make, engine size and model # when asking questions. In your case the mileage would also be helpful. If your intake and/or exhaust valves were leaking, you could get similar problems. If the valves were leaking, the fuel wouldn't fully ignite, foul the plugs, dump unburnt fuel into the exhaust pipe or blow it back through the carbs into the air box.
To check the valves for any leakage, bring the piston to TDC of the compression stroke. With an air gun, blow into the spark plug hole and listen at the muffler end and air box. Repeat for each cyl.

Its very possible that your floats are stuck, try tapping on the carbs with a plastic mallet or a piece of wood. Try to get the carbs to resonate and free the floats. Other than taking them apart and checking all the components, this is a possibe cause.

Sounds to me like yor old carbs were probably ok.You said you installed them your self.Do you have a set of guages?The left bank has to be set ,then the right bank,then all four together.If you don't understand the concept i've just put forward,you need to hire a competant tech.

Would have helped if you said what yyear and model. Sounds like you have an air leak with backfiring. If its in exhaust its afterfire. Check air filter and ignition timing. Float height may be off.

A quick fix that might help, take a wood clothes pin ( for hanging clothes out to dry) put it on your fuel inlet line. This will slow down the flow of fuel. I have done it before and it work for me. Maybe it will work for you too.

Is your choke in the on position?Are your floats closing the float needles? Are your jets to large?These are the things you need to find out
