ok thanksNot much ... clean the TB with sensor safe (e.g. MAF) cleaner, then just mask the mouth, the connector and the bottom properly with masking tape and spray on several LIGHT coats with 5 mins in between. Remove masking tape after an hour ... let it cure over night. done.
I used carb cleaner on a soft cotton rag but was very careful to stay on the outside only and away from the plastic parts (connector and pcb cover).
