I have posted two of these three questions before and got no answers. Either dumb questions or no one knows the answers. I am a first time builder although I helped my son build a 10.
#1 - When doing your first engine start did anyone find a lifter that didn't pump up when pushed on with a hammer handle a per Rotax instructions? I was told by Rotax service people at Oshkosh that about 1 in 100 engines has this problem and if not fixed it will do engine damage.
#2 - When installing a thermostatic oil temperature controller how do you purge the air between the thermostat and the oil cooler?
#3 - If you buy a non Vans Rotax it may come with a airbox to which the carb vent tubes could be attached. This to me would equalize the air pressure between the intake and float bowl to allow for automatic mixture control preventing a rich condition at high altitude. In the 12 should we be connecting the vent tubes to back of the air cleaners to balance the pressure also? I may be way off on this one - your thoughts.
