Ok guys, 1971Evinrude 100hp again...
I have dissembled both of my carburetors. The bowl looks clean, but has a little junk.
The seating for one of the slow speed needles is completely gone/dissolved. I can only pull junk out. WOW
I am pretty certian this was causing a rich condition and dropping my #3 cylinder.
Now, my service manual does not go into specifics nor does it show me what to clean. Where is the idle speed circuit? Where are the high speed jets? I am so confused right now...
