Guest Dodge Deluxe Posted May 22, 2009 Share Posted May 22, 2009 Greetings,I am needing some assistance on how to check and set the float in my Stromberg carb. I have a '39 Dodge sedan, I need to know first, what is the correct measurement and second how do you check it and/or set it? Where do you measure and what are the specs?Any help appreciated.

RobV Posted May 22, 2009 Share Posted May 22, 2009 DDeluxe,What model Stromberg? I just set the float on my '36 Packard a couple weekends ago. Should be about the same if the model of carb is the same.Rob Link to comment Share on other sites More sharing options...
hwellens Posted May 22, 2009 Share Posted May 22, 2009 Based on my Motors manual, if you have a BXV-3; the fuel level should be 5/8" below the the top surface of the float chamber with the gasket removed. Most of the time the float is adjusted, but, looks like you will have to put gas in the carb and measure the gas level down from the top when the needle valve seats.

RobV Posted May 23, 2009 Share Posted May 23, 2009 If your car has a fuel pump, then from what I remember, the float has to be set with the proper pressure on the feed line. Link to comment Share on other sites More sharing options...
nearchoclatetown Posted May 23, 2009 Share Posted May 23, 2009 Dan, I forget. Does your car have an elctric fuel pump. Link to comment Share on other sites More sharing options...
Guest Dodge Deluxe Posted May 23, 2009 Share Posted May 23, 2009 No electric fuel pump, it's mechanical. I emailed Clive at Stromberg Carb today, he told me to pull the carb and turn it upside down. He said while holding it upside down, the top of the float should be flush with the top of the float chamber. Mine was slighty higher so I lowered it so it was slightly lower than the top of the chamber and reinstalled the carb. It seems to be running fine in the driveway, but I have not tried venturing down the road yet, need to make sure I have someone who can pull me back home if need be.Regards;Dan Link to comment Share on other sites More sharing options...
nearchoclatetown Posted May 23, 2009 Share Posted May 23, 2009 Venturiing down the road? Is that a carb play on words? Link to comment Share on other sites More sharing options...
Guest elmo39 Posted May 23, 2009 Share Posted May 23, 2009 instead of 5/8 try 5/64 Link to comment Share on other sites More sharing options...
Guest elmo39 Posted May 23, 2009 Share Posted May 23, 2009 I think i should say a bit more about this , i have owned Chrysler product cars since 1958 when my first one was a 1938 Dodge , since then most of the cars , up untill about 15-20 years ago when American car supplies dried up here, were mainly Chrysler sourced, apart from a 55 chev , i should be shot for selling , not for the quality(although it was an excellent car ) but for the price they are now getting .I still have a 39 S6 DeSoto and a 1954 DeSoto diplomat (which is a Plymouth in disguise) , in all that time and the cars i have owned , the onley work that i found needed to be done on the carbs was a good clean out and maybe replace the needle valve ,usualy all i have ever had to do is unblock the jets , it helps to own a compressor, i have never had to adjust the float level , or replace gaskets , remember that the float level can only be altered by some one physicaly altering it .

Guest Dodge Deluxe Posted June 21, 2009 Share Posted June 21, 2009 Well, I got my float adjusted now and she's running good.Dan Link to comment Share on other sites More sharing options...
JACK M Posted June 21, 2009 Share Posted June 21, 2009 Sometimes those floats get heavy and will need a little adjustment. Just before they need replaced... Link to comment Share on other sites More sharing options...
