Float level is fine,I think DennyW is right.My new wires should be here wednesday,I'll find out then.I noticed that it coughs back through the carb some when I try to crank it.I think the spark is jumping to another cylinder causing this.I just hope this hasnt hurt my bearing on this new motor.I installed new plugs and they went black after about 3 minutes of running.Three different carbs,same problem,so I dont think its the carb.It has to be ignition.
