i have a hmf full system and i put the 180 main jet in and left the pilot alone. It ran good except for a little stumble at the 3/4 throttle so i bought a 175 main and 48 pilot, put clip pos. at 5 w/ air box removed. And it runs worse than before. + it whistles like no other 2. :evil please help.
thanxs for any advice
