The Ordnance Survey Namebook Entry (1855-57) for Limekiln Burn reads –
A Small Burn forming a porti [portion] of the boundary between Old and New Cumnock, after a short course it falls into Guelt Water
It flows northwards from just beyond the Guelt Lime Works to join the Guelt Water and forms a boundary between the parishes of New Cumnock to the east and Old Cumnock to the west.
The burn takes its name from the limekilns at the Guelt Lime Works. The kilns sit on the New Cumnock side of the boundary and the limestone quarry sits on the Old Cumnock side of the boundary on the lands of the Over Guelt, from Welsh gwellt Old Welsh guelt ‘grass, pasture’ .
However it is interesting to note that in the OS Name Book all three authorities for the mode of spelling of the name, i.e. Robert McNaught, tenant (Craigshiel); John Lammie, Clickluoie (Clocklowie) and Mr McGregor, New Cumnock call it Fleck Burn. A reference is made to OS Name Book Entry for the parish of Old Cumnock where the name Limekiln Burn is said to appear on an Estate Map and therefore wins the day.
A possible Gaelic origin is fliche ‘moisture, wetness’  and is found in Fleuch Larg in Wigtonshire which W.J. Watson considers to be Fleuchlarg ‘wet pass’ near Gatehouse of Fleet, Wigtonshire  and Sir Herbert Maxwell as Fleugh Larg as Gaelic fliuch learg ‘wet hill-side’ .
While Scots flake, fleck ‘hurdle, piece of framework’  seems unlikely.
