----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- I have had three events of vapor lock before I corrected the problem. Two occoured with 100LL and one with mogas. All events happened with the engine compartment hot and during low speed operation.
When the engine compartment is hot, the fuel in the line from the firewall to the gascolator becomes hot enough to form bubbles. In a low speed climb or slow flight attitude, the fuel tank is not much above the height of the carburator. In this situation the engine can vapor lock if there is a high spot in the fuel line between the firewall and the carb. There is no way for the bubble to vent throught either the tank or carb. The engine woll sputter, loose power and the nowe will drop. When the nose drops, the bubble can vent and power will be restored. The cure is to make sure that there is no high spot in the fuel line that can trap a bubble in a nose high attitude. Good luck, Bob Condon __________________________________________________ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ___________________________________________________________ T O P I C A The Email You Want. http://www.topica.com/t/16 Newsletters, Tips and Discussions on Your Favorite Topics
