Hi everyone newbie here, any advice will be much appreciated, have just bought my 3rd daihatsu fourtrak with the knowlage that when she reaches 2000 revs she starts to judder and cut out. Have checked all pipes and put airline through, that didn't solve it. Run a seperate pipe from the primer down the neck of the tank then she ran ok. so run new line from the primer straight to the tank, but still kept pulling the primer down and starving the deisel, have changed the fuel filter taken the tank off twice and checked, am loosing the will now as it's my 5th day off trying, any advice will be grat
