...Jan, is your trike electric start...
Just a few years after mine, they did start installing electric starters on them.
However, mine being the first version, it merely sports a string with a return spring on the right side of the seat.
(Same starting system you find on the smallest Briggs & Stratton powered lawnmowers)
When fully assembled, does yours have the head/cylinder completely enclosed as well, and cooled by fans on the flywheel, to keep it from getting too hot when driving very slowly for extended periods?
