QNH and dubtrub
You are both correct I think!!
I used the "taxy with carb heat applied" method tonight and had a smooth engine speed advance on take-off.
I used the carb heat far more than ever before and it seemed to work. After a descent (with carb heat applied) I deselected carb heat AS full power was applied (ie both plungers in simulataneously) and the problem had gone!!!!
I played around for a while and tried descending for about 30 seconds at 1500 rpm without carb heat and then going into a climb. It had a flat spot......
Thanks chaps.
This just leaves me wondering one thing........
......was my EFATO 6 weeks ago caused by this?
