Correct timing setting for Type W engine?

[PowerRam348]

welcome to the site. as for setting the timing, i was always told to diconnect the vacuum advance when setting the timing. but it more or less comes down to preference. again, welcome to the site and there is lots of info here and good folks to talk to if you got questions.

I decided to go with the instructions in the factory manual, but now wonder if there is a good reason to disconnect it when setting the timing. I was thinking at idle it wouldn't be moving the advance cause pretty much no vacuum factor until pushing the accelerator. Is this correct thinking?
It was set at 5* BTDC, which was a little "lo"?

I usually run the middle grade of gasoline, Chervon.

Was getting a rattle when it was cold going up an incline. Could have been the Champion plug?

What do you think?
