I have a Redcat MPX 150 which has a gy6 150cc and recently i took the carb apart and cleaned it. Now when i start it it will idle and rev fine but it can not make it up a slight slope... Before i cleaned the carb it ran fine slow but then bogged down at faster speeds. Any ideas?

When reinstalling the belt i put it on even and not big at the driven and not small at the drive clutch side.
