i just recently aquired a honda 350 4 trax it never ran when i got it so i first rebuilt the carb it nice and clean now ... but i have no spark ... changed the cdi to a known good one changed plug to a new one ... checked the coil and is good but no spark does anyone have any ideas i was told the previous owner has never got it to run after he lent it out to a buddy... help me please this was going to be my hunting bike

 

You check the pulse generator?

 

When you checked the coil did you check plug wire from coil to spark plug boot ? I ran into this once on a 96' model Polaris Sportsman 500HO , the coil itself was good but the high tension Plug wire to plug boot was burnt 3 inch from the boot to plug ; the Sportsman 500HO had been running great untill it was submerged in a cattle stock pond overnight !
Hope this is of some help to you , williebee..........
