<div class="PlainText">If it is dumping gas that badly, then it is not a problem with the metering needle. That is really a fine tuning device.<br>
<br>
That much gas may be from the float chambers having too much fuel. Way too much.
<br>
<br>
Check the pressure in the fuel line. If it is too high it will overcome the float valve.
<br>
<br>
Maybe the float valves are not sealing? Maybe the floats are not adjusted properly? Or not actually floating and are just sinkers?<br>

> I?m hoping that someone out in Triumph world can provide some clarification on carburetors. Currently, Zenith Stromberg carbs on my 1975 TR6. The car has been running poorly since Trimphest (too many RPMs?). And then it died completely but turned out
to need a new rotor. Asked the mechanic, Mike, to take a look at the everything to figure out what can be made better. What he found was the carbs were dumping gas into the cylinders especially when starting, to the point the gas was washing down the cylinder
walls preventing the rings from sealing. Result was a lot of white smoke.<br>
