Before you get any further, yes I know I should have bought an OS instead, but nevertheless...

I have a .90 Super Tigre that is only about 6 months old and I've run about a gallon of fuel through it, but I cannot get a decent, low idle regardless of adjusting the needles. The best I can muster before it shuts down on me is about 3k - 3,2k rpms, which I feel is well above the specs of 2,5k rpm for idle.

Also, the highest top end rpm I can get is about 13k rpm. Is this the expected top on the ground? I know it will unload in the air and achieve a higher rpm reaching towards the 16k spec, but 3k rpm seems like a big gap.

Any ideas on how to improve the performance?

Or am I just being too picky in general or because I am expecting more from a Super Tigre than I should.

Thanks.
