Hmm I'll check into all the things you guys brought up, good advice, I have a feeling I checked the carb set screw and when I tightened it I wasn't pushing down on the carb, maybe that's all it is (wishful thinking).

I can tell you there is no fuel or gunk anywhere there shouldn't be, the head is sealed up nicely, the backplate and front seal look good, but the tuned pipe where it comes apart in the middle has some gunk from where the rubber o-ring inside isn't being pushed into the groove, when I took out the cone looking baffle it was helping to hold it in place.. But it's very minimal buildup.

The weird thing is the temps are dead on consistent within 5 degrees F or so, and when I say the LSN feels rich, it doesn't accelerate quite as good as it could, it's very minimal like it almost wants to stumble when I left off but it doesn't. I'm just hesitant to lean out the LSN as I may need to compensate that with more HSN, I'll post some pics of my needles when I get home in an hour.

If I back the HSN out more then flush how much room do I have before it comes out?

Thanks guys!
