If your engine is running correctly there should be very little unburned gasoline expelled from the engine into the exhaust system, let alone enough to burn or explode. If there is, you have a problem in your engine; look there. You can get excess gasoling accumulating in the exhaust system if the engine is running WAY too rich, or lean enough that the mixture doesn't burn in the combustion chamber. Or from bad timing or valve leaks. Jim - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA *******************************
