So the “pig valve” it’s been called many things- is on the left side of the gas tank and it can shut fuel off or turn it on- after I cleaned the carb up, redid my lines, and cleaned out my tank, today it’s working like a champ and idling well! I’ll send a pic, I didn’t put it all the way together bc I am going to rebuild the top half just because everything else was so rough I know the rubber seals are toast. But yay and cheers!!!
