Hi guys i am new here but read alot of posts and problems from others that helped resolved mine but not this time.. i cant figure out why my left side wont fire or almost never unless i punch it. Carbs been cleaned coil replaced. Wires switched up from plug to plug and still left side not firing.. took gas tank vavle apart thinkin maybe a restriction but all good.. compression test 145 exacly on both.. carbs are synced.. choke tube is atached. Runing leaner witch it never did its weird thanks for your time
