503 Rotax wants to die
in 2 Stroke Technical Questions
9 years ago
I have a question and thought I'd get some input. I'm running a
challenger 2 with a 503 rotax. Today when I powered up to take off, it
would not go full power on the RPM'S. so after turning around on the
runway I tried again and on the second try I had full power and RPM'S
were normal. Then it ran smoothly for about 30 mins in the air and then
after landing I powered down (pulled throttle all the way back) and it
wanted to die but it didn't. So I powered up again and then powered down
and it tried to die. Not sure what to think. The week before this
happened I powered up running down the airstrip and right before take off
the engine surged for a split second, so I noticed the fuel lines had air
bubbles and ordered a new fuel pump. After replacing the fuel pump, Fuel lines, air filter, fuel filter, spark plugs. I
thought everything was going to be ok but then this happened. Do you have
any suggestions?
