Bondo I have a question for you this may sound stupid but I run in to a lot of stupid stuff ! I put my new plugs in and new cap wires and rotor button and new ignition module , anyway I was trying to check timing on it and I hooked up the special tool connector and started engine and then hooked the wire to positive side of battery and it killed my engine I have tried everything keeping it idled up and even moving the distributor both way and as soon as I hook up the wire to time it to the positive side of battery it kills engine ! This is driving me nuttz I don't want to ruin the engine I checked the timing on it with out the special tool,and it shows right there at zero degrees and I took it out today and it ran but was popping thru the carb so I turned the distributor to the left and got rid of the popping and it flew across the water right at 50mph before I let off of throttle anyway I didn't want to run it to much with not knowing for sure about the timing ! Any help would be greatly appreciated . Thanks
