Hi Guys,

I have a gx 5prt in a truggy. Today went and did some practice and the first tank it ran ok. Second tank and it wouldnt run as soon as i went over 1/2 throttle it bogged heavily. So i leaned the HS needle 1 hr same went another hour better another hr better again and still good smoke, but everytime i top up the tank it runs boggy once i go for full throttle. Any ideas?
