Blue:

Yer trouble is with the two resistors. You only need the 0.9 ohm resistor. The extra is reducing the spark energy way too much. A transistor system uses two resistors, a 0.4 ohm and a 0.6 ohm. The basis system for the old-fashioned way of creating a sparl only needs a single resistor...a 0.9 ohm to match the MB coil.

But, since you seem to have given up on points, best of luck with the Crane (but, I'd keep the 0.9 ohm resistor, points and condensor just in case something fails on a dark night.)
