Answered via PM.
Answers to most questions regarding vertical to horizontal conversions with most 2 cycle Lawn-Boy engines (not 'M's, 'C's or 'A's) are posted throughout this site (various threads).
Things are just too nuts for me to document all of it in one place. Perhaps a dedicated thread? Not up to me. May not be enough interest to keep it alive for very long.
On occasion, my inbox is inundated with questions. About half of them come from this site. I would rather answer questions in these forums so that anyone/everyone, who may be interested, can benefit.
Keep in mind that the use of L-B engines is not a cheap or easy answer to replace the garden variety Briggs or Tecumseh 4 cycle.
Thanx,
Rusty
