I have a strange issue. I just got my 1979 Maxi going. But it is easier to start by holding the clutch in and grabbing the back wheel and spinning it. It cranks right up. But using the pedals is not as effective. I did have to remove the clutch cover to replace a broken actuator lever and had to adjust the clutch but it seems to be ok judging by how easy it is to start by grabbing the wheel. Any ideas? Maybe the freewheel is slipping?
