I'm not sure what I'm doing wrong. I hava a norvel .25 and have set the low end needle valve as follows.
let engine idle for 45 sec or so and run throtle up quickly. Motor was spiting fuel (high end was set about 2 to 300 rpm bellow max) so leaned out a 1/4 turn at a time. I did this till I got a great transition form low to high. after starting motor can hold plane up and motor doesn't sag at full throtle.
heres the odd part. the low end needle is almost closed, as in 1/8 to 1/16 open. instructions call for 1 1/2 to 2 turns open. anyone have any thoughts?
