I did pretty much what you did. Bumped the timing to 18 degrees at idle. Your 12 mm/Hg at 900 RPM is a little lower than I would have expected for your engine. Mine is around 17 mm/Hg at 900 RPM.

That said, I lowered the float level to the bottom line and haven't had any problems at normal speeds.

However, If I do have to get on the brakes really hard, there is still a bit of a stall, but by then, I will have hit something and the stalled engine will be the least of my concerns.
