carb air boxes

Post by dlrude » Tue Feb 24, 2015 09:45

Hello,

I am repairing a 7ccm with a c90-12f and using the drawings to put it back together. The engine installation drawing calls out a different carb airbox number depending on which fuel system that you have and which carb.

This plane has a 26 gallon fuel system and a Stromberg carb so it calls for a 4-877-3 air box.

Looking at drawing 4-877 rev. G I just can't see any mention of a -3 mod or part.

Does anyone know what the -3 implies? What is a -3 box compared to others?

Thanks, Dave

Dave, everything I have seen uses the 4-601 air scoop assembly. I don't have the 4-877 print to look at. Every Champ I have ever seen has this air box. Except for the L-16 with fuel injection. David J./Jasper, GA
