LUSCOMBE AIRPLANE CORPORATION GARLAND, TEXAS November 6, 1950 TO: LUSCOMBE DISTRIBUTORS & DEALERS & OWNERS OF MODEL 8 SERIES LUSCOMBE AIRCRAFT FROM: ENGINEERING DEPARTMENT SUBJECT: MODEL 8 AIRCRAFT A. CARBURETOR AND CABIN HEAT It has been brought to our attention that the one stack exhaust systems on the older Model 8 airplanes are supplying marginal carburetor heat under severe or unusual atmospheric conditions. If you are having difficulties with this system you may want to replace your exhaust system with the latest type. Two new exhaust and heater muff kits are now available that will increase your carburetor heat output to meet the latest heat rise requirements and are as follows: 1. The 09607 exhaust assembly includes two stacks, larger carburetor and cabin heat muffs, and the necessary attaching parts. B. FUEL VALVE It has also been brought to our attention that the Harding fuel selector valves have presented some operational and service difficulties. The 1950 model 8F Deluxes now use a twin fuel valve system which offers a simplified and more positive operation. If you have had difficulties with your selector valve, this twin valve system is recommended. This kit is available for all Model 8A, 8E, and 8F airplanes.
