Default RE: anyone running a Walbro 488 modded carb

are those settings not the wrong way round shouldnt it be 2 1/2 high 1 1/4low?.i have a book for settings on the 230 and 260 rc car carbs which should be similar and the factory settings say 1 3/8 high 1 1/4 low so i maybe try those and see ?.from the sounds of it the low needle is too far open id go for 1 1/4 or 1 1/8 and lean the high out a bit starting at 1 3/8 and adjust a little at a time.
