Make sure you have a good spark plug.
Since you have flywheel off, check the white wire coming from stator going up to the module, make sure there is no chaffing or breaks int he wire, this can ground our module.
Next, there will be a ire coming from the ignition switch to the stator or the module, that is the shut off wire or grounding wire. Make sure it's not broken or rubbing and grounding out on frame. If you can, unplug this wire, then check again for spark ( requires putting everything back together) Sometimes the witch goes bad and grounds out the module when in run position.
If still not spark, then your module is probably burnt up.
Dale's conversio is not a bad price, but you will have to make sure you have a good charging system since it runs off the battery.
