RE: Old 1/8A engines...
The venturi is longer on the repro Infant .020 than the original.
I suspect it offers better fuel draw as some will do by extending an OK Cub .049 venturi to above the exhaust ports with thin wall tubing.
If you've ever had a Cub .049 sag or die on launch the extended venturi will cure it.
