Even a cheap one will work but don’t depend on the markings on the regulator. You need to hook up a vacuum gage to set it to about 1 1/2 to 2 psi. At least that’s what my TR6 ZS carbs liked best.<br><div>

Subject: [TR] TR6 Stromberg question<br>
<br>
<div id="AOLMsgPart_1.2_c425e000-65cf-4115-8c1a-67dac2ee440e">
<div class="aolReplacedBody">My friend's TR6 was running poorly. After the car had been running, and was turned off, I noticed drips of gasoline dropping from the port below the forward carb just in front of the intake manifold. I concluded the Gross jet was
not stopping the flow of gas to the carb and gas was getting pushed into the engine. So I replaced both float valves with standard valves and also changed both floats. After putting everything back together, I ran the car for a few minutes and turned it off.
It was dripping gas out the same port. Looked in the throat from the air filter side and saw a small puddle of gas in the lower area right in front of the venturi. As far as I know, that means the gas isn't shutting off. Perhaps I didn't adjust the float correctly.
Or there is something at the fuel inlet orifice allowing gas to bypass the valve. Is there anything I am missing here? Could the enrichment valve (choke) be the culprit? I haven't touched that yet. I adjusted the new float to fully close the valve when the
mold line of the float was parallel with the horizontal edge of the carb where the fuel reservoir attaches.<br>
<br>
Am I missing anything else here? <br>
<br>
Thanks <br>
