i wish it were that simple i took the filter out of the carb about a year back because the old fuel tank had really clogged it up. the only filter i have on it is the sock on the end of the line in the new tank. dont know if this helps or not but i have noticed the fuel mileage has gotten really bad went from like 15-16 to around 8. does that mean i am pushing more fuel that i am using or what.
