i checked the timing and changed the plugs,cleaned carbs and fresh fuel.The motor seemed to run better after I changed the plugs then went back to the miss after a short time.Seems like a hard miss at idle then shuts off imediately.Idles at around 900 in neutral and about 800 in gear.Top end seems to be fine.Getting about 4800 to 5000 rpms.pulled the plugs and they all looked good.I think it might be a coil but not sure how to isolate it.I have a clymer manual but cant find the info Im looking for.Any help would be greatly appreciated.It has the Prestolite ignition.
