Does anybody on the site have any experience with modifying a 914UL by replacing the carbs with a fuel injection kit such as what is offered by Edge Performance? I'm a new user of a crate 914UL engine on a MTOsport gyroplane. I'm not satisfied with the somewhat variable start-up performance of the engine which seems to place a large load on the reduction/final drive clutch. This doesn't seem to be a problem when starting either a hot or cold engine, but has been noticeable when the engine is warm or in between. I'm thinking that getting rid of the carbs would solve this and also provide better fuel economy. I'll probably operate my gyro as is for the next six months or so before considering the fuel injection upgrade. Any comments would be very welcome, cheers, pmelby
