I HAD A LITTLE EXTRA MONEY AND CHANCED UPON THIS LITTLE GOODIE. IT IS FROM 1973 YET STILL CLEAN UNDER THE HOOD.
ONE COIL IS BLOWN, THE PROP IS CRACKED AND A SPARK PLUG HOLE IS STRIPPED OUT. I PICK THESE MOTORS UP WHEN I SEE THEM SO I CAN KEEP A PARTS INVENTORY THAT IS BOTH USEFUL AND PRODUCES SOME SHOP CASH FLOWING IN. IT ALLOWS ME TO BUY PARTS AND TOOLS FOR MY PROJECTS.
IT HAS BEEN A WHILE SINCE I HAVE POSTED BUT MAINLY BECAUSE OF MY LACK OF PROGRESS SOLVING THE ISSUE WITH THE WATERWITCH'S MISFIRING. I NEARLY DISASSEMBLED THE ENTIRE MOTOR LOOKING FOR SOLUTIONS. I FOUND A BAD CRANKCASE GASKET SO I CUT IN ALL NEW ONES. AS I WAS REMOVING IT FOR REPAIR IT PULLED THE DRIVE SHAFT UP. AFTER WARDS I COULD NOT GET IT TO GO BACK DOWN BECAUSE OF THE WATER PUMP CAM SO I HAD TO PULL AND DISASSEMBLE THE LOWER UNIT ALSO. BUT FINALLY, RIGHT BEFORE SETTING IT ON FIRE, I FOUND THE PROBLEM;
THE SPARK WIRE ON THE WATERWITCH APPEARS TO HAVE BEEN CRUDELY CONNECTED TO THE COIL IN MANUFACTURING. THE COIL HAS A SMALL METAL LOOP WHERE THE SPARK WIRE IS TWISTED ONTO AND POSSIBLY SOLDERED. MY CONNECTION HAD SOLDER BUT IT FAILED TO FUSE THE WIRE TO THE LOOP. IT APPEARS AS THOUGH THE CONNECTION BECAME DIRTY AND/OR LOOSE OVER THE YEARS AND POOR SPARK WAS THE RESULT. HERE IS A VIDEO OF ME GETTING IT TO IDLE:
AS YOU CAN SEE IT STILL WILL NOT THROTTLE UP VERY WELL. I HAVE ORDERED SOME NEW RED SPARK WIRE SO I CAN REPLACE THE OLD ONE AND SOLDER IT ON PROPERLY. AFTER THE REPAIR IS DONE I WILL FIRE IT BACK UP AND TINKER WITH IT MORE. IT MIGHT RUN FINE WHEN THE AIR FUEL MIX IS DIALED IN AND THE SPARK ISSUE CAN BE ELIMINATED.
