Putting this here since it was hard to come up with.. I can't remember the main jet I have.. it's either 145 or 147.5. Pretty sure I went with stock pilot and clip in 3rd spot. Carb has a brand new $120 slide. WIll pull bowl this week to confirm main jet size, but it seems like the bog/loading issue is either clip or pilot maybe. Then again maybe my main is still off due to the smoke and spooge.
