My valve was flowing too much in the open position so I plugged the in line
to set up a maximum flow jet. In the process I lost much of the meat for the
connector fitting and had to take it to the welder to get a 1/4 inch plate
added. Got it back late this afternoon and will start with .120 dia. What is
the maximum flow I should be looking for? Karibian

Well my guess on your engine is 180 HP. At a full power BSFC of .65
you will need about 117 pounds per hour or about 20 gallons an hour
max.

Now we need to know what pressure you are dealing with.
Here is a chart for 2 psi. Based on this chart I would say
a .120 dia jet is way too large.

If your system is only 2 psi your six jets will all have to
be around .035 inches in diameter. At 8 psi each jet would be
about .017 or .018 diameter is my guess.

There is nothing stating that you have to squirt fuel in all
six holes. The engine might run fine by squirting fuel
only into the two ports in the center housing. That way you can
run a higher fuel pressure and or larger jets.
