Starter

What he describes is classic starter fail symptoms.
(especially if he smacks it with a hammer and it works again):D

I took one down one day to have them test it for a warrantee replacement and the guy dropped it on the way over to the test bench, and of course it tested good (to them anyway) so they wouldn't give me a new one.
Kinda peed me off because I knew for a fact it was bad, and why it worked for them after they dropped it.
It quit again the next day and I finally got the new one, and when I explained about dropping it they looked at me like a deer in the headlights.
