Improves Flight Safety - Lower Operating Cost - Superior Quality

Newer, Robust Gasket Material

• Eliminates legacy gasket relaxation causing body-to-bowl fuel leaks (For more information see Service Bulletin MSA SB-17 & Lycoming SB 366C)

Increased Float Clearance in Bowl

• Larger machined cavity allowing more clearance preventing floats from sticking (For more information see Service Bulletin MSA SB-4)
• Increased fluid volume for optimal upper range performance

Stronger & Lighter Main Body Material

• AL 6061-T6 Billet Machined Throttle Body to Bowl
• 30% increase in yield strength over legacy cast material
• Eliminates drain plug thread deterioriation causing leaks
• Legacy castings are prone to cracks and porosity
• AVStar's carburetorrs average a 15% reduction in weight by design resulting in lower operating costs

Corrosion Resistance 

• Fully anodized billets have much higher corrosion resistance than legacy castings
• More stainless components in each fuel system

Performance

• Billet machined venturi's for improved and consistent air flows
• Improved mixture cut-off sealing
• Optimized air fuel metering using advanced fluid dynamic analysis validated by the world's largest piston engine manufacturer, Lycoming Engines
