Welcome , I have a Foreman 450 , in the fuse box is a diode , a black square piece that is about twice the width of a fuse , if it goes bad I know it won't start by the button and will by the pull start , that kinda fits your problem , also check the fuse holders as I have had to cut the wires to one fuse and install a in-line fuse holder
A mole catcher ! I am hunting moles right now around my house , they are making a mess of the lawn , I got one of the spring loaded spiked traps but have yet to get one with it , my best way has been to flood the tunnels with a hose and sometimes they pop out , I have got 3 that way but there are more , any tricks to getting rid of them !
