i just recently put my assault back together from a new tunnel up. got a small air bubble just behind the oil bottle how/any tricks to remove it? i have already tried to hold the oil pump wide open and start the sled and try to get it to suck through ran the sled for a good 10 mins couldnt get the bubble to move any, can kinda see the oil trickle by. or should i just not worry about it and just run a tank of premix next season? i planed on running the 1st tank premixed anyways. and the oil pump doesnt look to friendly to get to to bleed out. thanks ahead of time guys!
