~Hi I have a Honda FG315 Tiller and the drive pulley (vacuum operated) seems to have lost it’s strength pushing onto the drive belt? Thus causing belt to slip, I’ve looked for air leaks and tried a spray of belt slip but it’s just not up to it.The tiller is about  4 years old and I bought it on E-bay.
I think it’s over engineered, the fg314 has the usual spring loaded handle to engage the belt.
Any help and advise would be greatly appreciated DB
