B&S Vanguard 14HP V twin OHV.. model 294440,Type 0414-01 5097, code 920904-11 , Am looking for some carburetor information.

Looking for carburetor information, Float level and one external adjustment. Does this adjustment adjust the fuel or air.
I have it running but runs a little rough at slower speed, runs good at higher speed but seams to be lean running. Pull the choke out it does run better at high speed. Both cylinders have 148 and 150 psi compression. If any information I would be grateful. Have changed fuel lines and one short vent hose that leads to one head foe venting. Cleaned the vent hole in the fuel tank, Found the gas tank was pressurized one time. Ran much better after replacing fuel lines, before it would not run. This engine is mounted in a older utility cart. I did change the fuel pump.

If you install the float needle and pin in the carb cover and then turn that part upside down the float should sit parallel to the carb cover. The valve adjust fuel. Or for a little education. If the adjustment needle is pointed then it adjust fuel and further out you turn it the richer the mixture. If the adjustment needle is blunt/flat on the end then it adjust air and the further in your turn it the richer the mixture.

Thank you, never saw a carb like this one, easy enough to check. Unlike other carbs, the jets are dry even though the bowl is full . Thanks again.

Thanks for all the help! 2 problems, fuel separation was a small part, fuel pump was the big problem. After replacing I had the hoses mixed up for fuel supply ( hate to admit it) maybe it will help someone else in the future. Again thank you all.
