If it has 8k miles, I would think the starter had been used successfully. FLAPS ought to test for free...battery, too. And check the wires & connections while you're at it.
You might consider pulling the heads to get a look at the bores. If they're bad enough, no amount of juice is gonna fix 'em, even if you get it turning over...you'll just ruin the rings. After only 18 months, I wouldn't expect any problems if the engine was buttoned up.
It would be nice if you could get a socket & breaker bar on the front crank bolt. I like the feel of turning an engine over this way, especially before cranking it.
I can't wait to try out my 400, but project is on hold 'til spring.
Good luck.
