ignition problem is solved! I installed the switch and still no spark but it was for several model years so it came with an extra wire that didn't have a corresponding wire in my connector so I used it to add a circuit that supplied current directly to the coil during cranking only. I've got sparky coming off the coil now that'll jump 3/4 of an inch. My problem now is getting it back in tune because of all the adjustments I did on it trying to get it started before I figured out what was wrong with it. It starts up but dies as soon as I open the throttle any at all. I've tried opening up and closing the mixture screw as much as 1-1/2 turns in each direction (i.e too lean to too rich) but it still dies when I throttle up. If I let it idle long enough to warm up it will accelerate without dying if I retard the timing and adjust the idle to about 950 rpms. Any suggestions here are appreciated.
