[AT] OT: success repairing small 2 cycle engine

[John Hall]

Speaking of soil tamps/compactors, I haven't seen one of the really old ones 
at an antique show in quite some time. The ones I am speaking of had a Wico 
EK magneto, I think they were made by Barco?I  have only seen one running. 
It took quite a bit of coordination to keep that contraption going. It 
definitely drew a crowd of onlookers.
