This is Tamco/Toku part number 430430D40 throttle lever, stocked at Crowder Supply as TK-430430D40. It governs how air reaches the working end of the rock drill. Wear on the sealing land is the usual cause of a throttle that leaks with the trigger released.
It appears on the TH 800 Rock Drill breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the full diagram library; complete tools are on the Tamco/Toku tool range. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
