CAD files for the Wallaby Engine
These CAD files are the size of the original plans. I wanted a larger engine and so scaled each linear dimension by 1.25
Engine Build = 1.25 Pattern Scaling = (1.25/0.98) = 1.276
Carburetor Build = sqrt(1.25^3) = 1.398 Pattern Scaling = (1.398/0.98) = 1.426
- Al casting shrinkage = 0.98
- Fuel volume requirements are a function of engine volume while carburetor delivery capability is a function of bore area.
