Sorry for no pictures it’s a Lifan 110 those Honda Chinese clones it starts perfectly as I put a whole new top end (piston jug and head) but now if I let it idle it slowly loses rpm until it fully dies the timing dots are in line and I did intake 0.003 and exhaust 0.004 and like I said sometimes when It dies a bunch of gas fumes come out the carb, I really have no clue what to do so maybe one of you got an idea
