Hey All,
I am experiencing my third fouling of my sniffle valve. IO 390 with Superior Cold Sump and Airflow Performance FM-200. Sniffle is fouling and sticks open providing enough manifold leak to disrupt idle mixture.
Removing and cleaning with solvent provides 10-15 hrs of normal operation.
Build is Lycoming Thunderbolt. Engine does weep small amount of oil down intake tube that Lycoming considers 'normal.' Sniffle is the $100+ model from Spruce.
Any thoughts here? Right now I am jamming a plug in the drain tube preflight and removing post flight.
