Dude, there shouldn’t be a gap when the plug is installed. Don’t try to tighten the plug to close up your gap. You will break something. It sure looks like your plug is hitting the main jet. That of course prevents fuel from getting to the jet.
In post #83 you asked: “AnyWho, do you think that might be what is causing my top end lean?”
Yes, of course. The plug is obstructing the jet. Get shorter jets like I suggested. Get them in the range of #138 to #148 so you can tune it.
In post #84 you asked: “why would they send a jet that was in it like that if it wasn’t gonna work?”
Who is “they”? You are the one that ordered the jets. We’ve been saying all along that your PWK is different. It has a removeable needle jet. That’s a kinda cool upgrade but it also necessitates the use of shorter main jets, not standard PWK main jets. If you order replacement main jets for a PWK you will get regular PWK main jets, but you don’t have a regular PWK. The removeable needle jet sticks out more than a standard PWK, so you need to use shorter main jets. The supplier of the knock-off carb delivered it with a shorter main jet, because it needs a shorter main jet.
Sneezy hit the nail on the head when he said “it's a $30 carburetor! You get what you pay for. So I replace a few parts. Still ahead financially with this in the long run.”
Check your bowl drain plug. Wouldn’t surprise me if you can see marks on the floor of the plug cavity caused by contact between the plug and jet.
Look in here. Check for marks caused by the jet.
