Wondering what I should set float and float drop to with long black slide and 4100 coil. Will be on a 17/70 gear rule. Any help or suggestions are appreciated!
 
Float drop should be somewhere around 1.050" float level should be .870 to .900 depending on track conditions.
Many times some oval tracks are so rough that fuel splash causes misfires / bobbles and the only way to reduce the issue is to decrease the amount of fuel in the bowl.
Sometimes you can coach the driver to take a different line than would be the normal fast way around the track.
Staying out of the rough stuff can sometimes be the fastest way around the track.

For MOST Kid Karts I would engage the clutch just above idle. Set the idle just high enough to keep it running on the grid or it there is an off track excursion.

Thanks jimbo! Already bought your float gauge last year, makes it so simple to quickly check float height every week. Must have tool in the trailer!
