Patrick, I thought his comments were interesting, but I doubt his inference of power failures, and icing problems. We have seen problems with mechanics not properly tightening the fuel pump cover after an annual; and have a pump failure; because of sucking air instead of fuel.... But if you are observent, you immediately see the fuselage tank gauge dropping....and find a place to land and refuel the fuselage tank......and properly tighten the cover bolt - or replace a failed fuel pump. I have never experienced ( in almost 20 years of Coupe ownership) a power failure in my C-85. However, when a carb needle valve is replaced with the Delrin plastic tip, then a weight must be added to the carb float....and if done improperly the weight may rub the carb body and stick, causing problems.... ( applies to all engines and airplanes using the Continental Engine and Carb....not just Ercoupes); and not draining water from the tanks and gascolater of course causes problems...... I don't buy the Funnell Effect he discusses, as the Carburetter mixture is determined by the density of the air allowed into the float chamber.....BUT if the mixture control passages are clogged, then this may happen...... (After cleaning the air filter, it must be properly oiled to trap dirt particles, or the mixture control will almost immediately clog..)... Proper maintanance ??? applies to all Continental & Lycoming, Franklin, and other Engines - on all airplanes. You should never have to add fuel to the fuselage tank, as the pump should keep it full. If you have to do so, check out the drain back pipe...May be broken off, etc...; and if the fuselage tank overflows, then the drain back line must be clogged, or the restrictor in the fuel pump has been left out....( the outlet fitting on the fuel pump is restricted to only allow a flow of about 7 gal /hr flow.) Weick designed a very safe system, after considerable study on aircraft engine failures....finding the gravity feed system to be the most reliable and safest. I believe that.
