It occurs to us that the spring in the valve silencer is so strong that it pushes so hard on the plunger and to the excentrisk mechanism that the valves dont close properly. This causes lack of vacuum at starting, and the car is hard to start.

The valve springs are all new.

Can it be so? How do we treat it?

Hi Anders,

It may be my lack of hands-on experience showing, but I don't think that spring in the tray there can compete successfully with the two (2) heavy springs holding the valve closed.  And if it were causing the eccentric to go beyond merely taking up any slack in the pushrod-rocker-arm-valve sequence (and thereby interfering with valve closure), wouldn't you be experiencing low compression on an ongoing basis?

Maybe check and see that the initial adjustment of the valves is correct?

Best regards,

Chris
