mikejs Posted June 1, 2020 Report Share Posted June 1, 2020 Im trying to get my neighbors ryobi bp42 leafblower running.He got it from someone for free,it didnt run.The air filter new,new spark plug,and fresh fuel added.The coil was also replaced since it was cheap money.You can crank it until your arm is tired and nothing happens.Did a compression test got 75 psi,cant find an actual spec.Did notice that the top of the piston and cylinder walls were very clean.Im thinking its a motor problem but i need other ideas.
