Ed,
I grew up driving diesel powered John Deere tractors and the smell doesn't bother me as much as kero. With a couple simple changes to the ECU, the Kingtechs start and run GREAT on diesel. Diesel is available at about 50 gas stations in Colorado Springs (and every other mid sized city) at about $3.75 per gallon, whereas kero is available at only two places here (one of which is not open on weekends) at $5.00 per gallon. I'm not sure why anyone would run kero, unless they have a 'purple' engine and don't have a choice.
Regards,
Gus
