Europa-List: Rotax Tacho

[Paul Stewart <europa@pstewart.f2s.com>]

Have just run the engine for the first time (914). All seems well with  
exception of rotax tacho. Advancing  throttle from  'rough running' to  
just smooth, the tacho jumps from <2000rpm to 4000rpm - numbers which  
I just don't believe. Anyone got any thoughts?

Unfortunately the rest of our engine instruments are a BMA EFIS1 which  
doesn't easily support an alternative tacho for the rotax.


Regards

Paul
