I've got a 99 Honda Foreman 450 that won't run because of no/weak spark. I've got the front fender off just for access. With the spark plug grounded to the engine, I have seen 2 weak arcs from the plug, in the total of cranking on it for a couple minutes. I had a spare cdi and plug and neither have changed anything, I'm not good with this kind of stuff, I had several offers for $600 on it but I wanted to see if I could fix it. Can anyone point me in the right direction here?
