Seems like I get a carb full of gas away from gym? Floats maybe? The tilting of the bike to load and unload has to be playing a part? I tried taking gas cap off in case it was vapor lock. If a main jet got plugged it wouldnt keep unplugging? Hoping for good advice before I start tearing it apart. My carb is a real pia to take out. Hoping I can adjust floats with carb still on? It has spark. Bike has run flawless till now.
There is a small screen in the fuel inlet pipe that could be partially plugged.You could try checking that before ripping the carb off.
