Try this: Keep the ignition OFF. Open the enricher fully. Keeping the ignition off, kick through 3 compression strokes. Close enricher. Get the kicker up on the compression stroke. Turn on the ignition and kick. If it does not start turn the ignition OFF and get it back up on the compression stroke. Turn the ignition on and kick. Continuously kicking with the ignition on can foul your spark plugs.
As a mechanic, we bought our little farm on a road with a hill, so that I can do the first test ride uphill, and then coast home if somthing goes wrong, anything to avoid the walk of shame (pushing your project home) hah.
