Do the ground wire thing. If still there will do what we talked about this morning. Sorry I missed your call. Was on the lake looking at a boat. Didn't leave the ramp till 11:25 and didn't figure you wanted me to call ya. Talk to you tomorrow.

Is the spark still erratic???? The only other thing that would cause it to do a high speed miss is water getting into the cylinder via a head gasket or exhaust divider plate. May be enough getting in there to make it miss and not showing on the plug. But the igniton was showing issues with the timing light. Later.
