QUOTE(mike_the_man @ May 31 2004, 02:33 PM) It could be running lean or rich. I can never remember which one it is that makes it backfire. Rich QUOTE Bullett.. I always though that a backfire was cuased by the mixture in the combustion chaber being fired when the valves were open. Which would be a timming issue, Thats because it is running too rich and extra gas is getting through that is burning off durring the spark. |
