All Plugs Fouling on Right Bank

float level set to low or you need to jet up. Remember, with out that metering rod in the jet hole, that's way bigger jet..........
Take the top off and check the float, jet it up and see what happens.
If you look down the carb and slightly open the throttle and nothing comes out the squiter,......probably float level set to low. set it back to the factory setting.

EDIT: check squirter pump while you have the top off of it.
