Rotax 912 ULS Bing 64 CARBURETOR FLOODING
in General Tech Discussion
12 years ago
After approximately 95 Hobbs Meter hours on my Van's RV-12, I discovered that both carburetors were flooding the engine because the float bowl needle valves were not sealing. Inspection of the viton rubber tips on the needle valves showed they were severely "truncated" near the conical tip due to permanent deformation of the rubber where they contacted the valve seat.
It seems to me that the service life of these needle valves should be more than 95 Hobbs hours. I burn Automobile Premium 91 Octane fuel here in California which has 10% alcohol plus whatever other additives California dictates.
Would appreciate any feedback other 912ULS owners may have had with sealing the float bowls.
