Dave,
When I drove Albuquerque to Breckinridge and return, up over a pass at 11500,
at around 9kft I advanced the timing a few degrees. I didnâ??t touch the carbs.
I donâ??t think the timing adjustment was necessary but it was easy to do.
If you sent your itinerary dates I might meet you in Co Springs and then there
would be 9 hill climbers.
