i recently purchased a Nexstar select .46 and have been trying to start it in the past few days. i fill the tank but it seems that it is always getting flooded. i has started twice for just a few seconds and then nothing. am i filling improperly? i know if fuel comes into the line going to the muffler it's going flood. how can i avoid this?

i plan to join a local club, but wanted to at lease have it running when i show up at the field. any tips would be great.

Thanks
Derek
