Ignition Coil for Robin 277-79431-01, 20A-79431-01

this did the trick...back up and running

Not sure

Works like a champ!

This coil is NOT an OEM replacement, however it works perfectly. Before you remove the old one, measure the gap between the lamination plates of the coil and the flywheel. You will need a feeler guage to do this and set the same spacing with the replacement. The only 2 differences between this and the OEM is this has slots where the screws go to allow for adjustment of the gap (OEM does not nor need to be adjusted). The spark plug wire is longer on this one. I would buy it again if needed, although we have had few coils fail.

Worked perfectly
