just going to throw this out there in case anyone has the answer.
Rotax 582 Bluetop, 220hrs (ish)
Lovely and smooth upto 4,000 rpm
6,000rpm full throttle again nice and smooth.
Rough and lumpy, 4250 - 5750 range
Rear cylinder spark plugs nice "biscuit" brown
Front cylinder, both plugs black.
Front cylinder CHT and EGT slightly cooler, both in flight and ground running.
Float bowls are clean
floats all okay
fuel reasonably fresh, tends to fly every 1-2 weeks.
No real signs of wear on needle
Carb rubbers good
raised clip on front needle to top to try and lean front cylinder
Any thoughts chaps?

The quickest way to fall out with people is, discuss politics.
