What is the difference between a needle valve and ball valve?
Datetime: 2016-06-17    Visit: 747
Needle valves  were always in low and high speed carburetor circuits used 
before the "Feds" sealed chainsaws weed whackers, lawn mowers, go karts, 

snow blowers. These were all gravity fed applications. Snowmobiles had 

or small diaphragm fuel pumps to feed carburetors that were located higher or 

at the same level as the gas tanks. Even then the fuel was controlled by 
needles and seats within the Mikuni Carburetors. Inside these carburetors 
fine pilot jet needles controlled the idle circuits The floats covered an 
ample supply of fuel to supply gas to the high speed jets. Still today the 
idle (zero pressure) circuits on Holley Carburetors are manually 
adjustable. It's a much finer precise adjustment than ball and gate valves 
are used in high flow high pressure water and oil applications.
