Hello all,
I'm just trying to work out some discrepancies between what's in my maintenance manual and what I've found on the web and in some previous forum posts.

The first thing I've noticed is that the manual says timing should be 5 degrees BTDC. But, in digging through the forum I've noticed folks suggesting anywhere between 7.5 and 12 degrees?

The other thing that I can't make heads nor tails of is the manual doesn't mention anything about disconnecting the vacuum advance hose and plugging it as part of the process. But, pretty much everything I've found online and in the forums says that's a requirement?

I'm running a 305D BTW. Any guidance or pointers would be greatly appreciated as I'm still very much learning as I go.
