Reply to "Weber jetting and float needle seat size"

Standard needle/seat size is 200.  I find that to be a good size for just about every motor with dual IDFs.  They offer them 150-250 in increments of 25.  While I've read that you are supposed to go to 250's when you break 200hp, I've never had the need to change needle/seat size up or down personally.
