Just fixed the no spark problem with a new starter solinoid run great for 2 hours, now revs at starter key position then when I release the key back to run and she stalls. The good engine has power at the plus side of coil on dwell an is bottomed out then goes to 36 or so on dwell at start. The bad engin has no power on the dwell meeter at run key position the bottoms out at start key position. ANY HELP PLEASE????
