Way, way better on cold starts than before and NO HOLE! I told it the area was smaller. Im guessing all the tables we cant see and corrections etc now think the throttle is small so it has to move the blade a larger amount.
I cant remember if Jessie said to make the value larger or smaller, but figured Id play around anyway.
So before anyone drills anything Id try this table first.
I can now drive at idle in 6th gear at 32mph on the flat, no jerking or lurching. Mind you cam is only 227/243-113
