I have been using the Fuji 4 stage for a number of years. It's a grea
t investment. Recently, I have sensed that the "spray fan" width is not wi
de enough. I then tested with water in the gun; the water is "thin" so it
should show the best performance.
I have (again) cleaned all parts of the gun with lacquer thinner. I ty
pically have replaced the "air tube/check valve" after each job - even thou
gh they seemed to work. The top cap and washers on the cup were recently r
eplaced (the new cap is a much better design).
I have ordered more air tubes with check valves to try again. However,
the only thing I don't know how to check is the air supply turbine. The f
ilter was changed in the recent past and appears to be clean. It appears to
deliver enough air.
Anybody go any ideas on what else to look for? Maybe I am "misremembe
ring" how big the fan should be. Are there any charts on how big the spray
fan should be when using water at 1 foot?
