I'm not sure, I tested it and it charges very well. The battery is almost always fully charged after the problem. When I had the problem last year I even replaced the battery with a new one. I considered the advanced timing issue but I have timed it very nicely and even asked the mechanic to check it out, He couldn't find anything wrong. When the starter is working, I only have to flip it for a second before it starts right up. It has a HEI electronic ignition which doesn't have anything to with the starter but I thought I'd mention that. Anyway, when I get home I will troubleshoot some more. If heat sheilding doesn't help, I may just invest in the "mini" starter or gtow69's hot start kit. I'm sure it's something simple, but I will take it one step at a time. Thanks
