I have a 49 cc bintelli beast , having some issues. My bf over filled it with too much oil recently and it was smoking and I haven't gotten it to crank back up at all...HELP PLEASE.... I've done a valve adjustment and I don't have a multimeter but I'm pretty sure it's not getting enough compression, it makes a ruuurrring noise but there's No "PoP" and it's just not seeming like it's trying to actually crank up! 😫 Any advice or thoughts appreciated!!!
