Trying to remove flywheel on Onan yesterday to fix/replace my starter bracket...

Found this thread
http://gmc.mybirdfeeder.net/GMCforum/index.php?t=msg&goto=176648&rid=3615&srch=onan+flywheel+bolt#msg_176648

I got a HF puller set (not the one Jon recommends, but other threads did) and the bolts did not seem right to set in the flywheel. Jon mentions buying 3/8 bolts in his thread, but I tried 16 thread and 24 thread, and 24 is definitely not it, and the 16 will only seat about three or four threads in. I am nervous driving it in too hard, because the flywheel metal has already pocked a bit on the first attempts. As in, pulled the first thread or two out.

And, assuming I can get a good bite into the flywheel, can I use my impact driver to turn the puller bolt? I have read to never use the impact putting the flywheel back on, but I don't see how to hold the flywheel from spinning and turn the puller bolt while getting it off.

All advice welcome. Thanks.
