the turn on lead doesn't need to be high current, it should work all way down to 10v or so. all it does is tell the ignition box to turn on. the bigger voltage wire that he has running to the battery is what provides the ign the real power.

seems you have good ignition and timing.
you have good compression.
the only other thing needed is fuel right?

what is the baseline tune on the carb you have and how is the carb setup now???
