"Do you have a fuel FILTER bef

"Do you have a fuel FILTER before the fuel pump? Not talking about a separator, a filter?

no filter before the fuel pump

no filter before the fuel pump.just a seperator which has just been thoroughly cleaned and a new filter installed.there is a small inline filter just before the carb.one thought is a blocked vent on the tank.i just find it hard to think its an electrical issue as there is no miss.
 
..."there is a small in li

..."there is a small in line filter just before the carb"

Ouch! Those are engine killers. Better check it out.

PS: The separator filtration should be 30 microns or coarser. Anything less than that and it can plug and lean out the motor.
