The carburetor on the engine in the pictures is the original Tillotson that came with the DLE30, it just has a Walbro pump cover on it with the external pulse fitting.
Anytime Imount an engine withthe carb through the firewall I alwaysmake provisionsfor ventilation at the rear of the fuselage. Where you get pressurization problems is when manufacturers cut lightening holes in the front fuselage bulkhead around the engine box, people that don't tape over those holesor don't provide an exit for air at the rear of the fuselageare rolling the dice every time they fly,IMO.
hey jody...one question, most of the 50cc doesnt go thru the firewall, somethimes the carb are really close but not goes thru. Making thhe ventilation on the rear of the fuselage helps anyway?.
No, only if the carburetoris through the firewall and then only if the it has a tight fuselage I should have clarified, sorry.
