I have a 1995 tomos targa lx with an A35 engine. I am currently not geting spark. When i swap engines and put my friends engine on i do get spark. This leads me to believe that the problem is in the eninge. So i bought a used engine from someone who swears it works, but when i put that one on i dont get spark either, but when i try to kick start it the back light flashes very breifly. Does this means there is power comin from the engine and just not enough to create the spark??? PLS HELP.. do i need a whole new magneeto??
