I would love to feel this thing get up to 6000!!!
This Briggs doesn't have a woodruff key but a standard key.
I spoke to Al Hodge and he said they didn't find any benefits in advancing the timing on the 35ers.
But I gave it a shot anyways.
Here is what I compiled with my timing key.
The key is 3/16 so if I cut off half, it would be an 8* advance.
If I cut off 1/3 of the key it would be a 5* advance.
I cut the yellow side of the key.
