Paraphrases to oneself: When i crack the throttle open over 60 mph... It seems to get better and kinda clears up.
So, I'm wondering if it is a dirty jet? Let me walk that out. Say I can run as fast as 60 mph. I'm all dirty from my backdoor visit and the yeast infection was kind of heavy. So I ran my soiled body at that speed to clean my self off. That told me I'd still be soiled all dry. So my body does not really clean up itself the higher it goes at speed. I need all circuits clean or I wouldn't start even. So I am not complaining about hard starting like if it was?: see how gummed up my needle jet is? So transitionally I'm not about to think carb dirty, when maybe my air cleaner is dirty, not my fuel mixture like all of a sudden my 'carb mixture screw needle' wants to move around with that kind of spring tension on it and the factory plugs those off so you don't wanna think the factory thinks that needle is going to move in the carb, right?
WOT does my air cleaner look like? Can I put it up to the sun and see any sort of daylight or is it slow clogged, even air won't penetrate it until you really add some throttle plate vacuum to override the dirt.
One entry at a time is begin with air cleaner not clean carb is try that first.
