I have a 4255 that lopes very badly at an idle. I have talked to a few mechanics that said to adjust the low idle bumper stop. Does any know how the procedure for this without putting the pump on a test stand. I know you have to adjust both screws on the back of the pump. It is a Bosch "A" pump. Thanks.
