with kits (WALBRO 400-606) we do not need pressure gauge to test the pressure?

It measures the lever height. The center leg should touch the lever, but without opening the needle valve. If you sweep it over the lever, the test pressure should not, or ever so slightly drop.
Beware. Each carb type has it's own measurement, and can be with, or without, the gasket. Read the F**g manual if in doubt, or if all else fails.

The spring kit allows you to set different pop off pressures on your carb

works fine in general,
slowed not very stable
to have a slow I must remain stable in 1850rpm.
How much time you got on this engine. If it`s low time an about broke in, you may just need to tweak the high/low needles. Have you got a tank filter in or inline filter for this engine if not you may end up plugging the filter screen on the fuel pump side of the carb.
