Answer. No doubt the vfbrators Sup
piled with the Ford car are especially
adapted to IT. but you should be able
10 make these new ones work more
reliably by reducing the spring tension
or adjusting them closer to the coil
cores. We think that your real trou-
BILE is that your magnetic is weak and
suggest that YOU have II tested and
put into proper condition. Your present
failure to start on magnetic is prob
ably due to Its weakness and the miss
ing of the engine. at slow speed IL
