Greetings to the crew,
Installed a TCI motor in a non-TCI chassis. Used the TCI box, the original points-type coils and tested the ignition system; bright blue spark on both sides, timing at cranking speed right on the "F" mark, so all appears to be in order.
The engine will not start. It backfires in the pipe and in the carbs, to the extent that it blows the carbs right out of their spigots. It appears as if the timing is 180 degrees out, but I can't see how that is possible with a wasted-spark system. So maybe it is something other than 180 out, but what and how?
Hoping for some brilliant insight that I have not considered; what could I have overlooked or messed up in my installation?
