I need some tech help. Yesterday I test ran the 79 1500 midget without the hood on and ran out of fuel. Before I could get towed a half mile home,a downpour started. So I fueled it up and it idled fine. Today I went to drive it and it is intermittently backfiring and sputtering under heavy acceleration. It ran fine until it ran out of fuel and got wet. My dad says the old ignition systems(with points which this has) were known to start doing this when moisture made its way to the coil or distributor. He told me to wd40 the coil and distributor and see if it ran better. Anyone got any advice? I ran it without the hood cause I just pulled the motor and trans to check the pilot bushing in the crank(thought I forgot to put it in 10 years ago).
