hello there! When I rebuilt my carb couldn’t get the accelerator pump out..I expected it to drop out. Anyway, I put it all back together but I have noticed a load of dead play. Should the spring/piston always be in contact with the leaver? It is only acting on it Having problems with misfire/rich running. Wondered if this could be part of the issue? I have lapped the carb so the 2 body parts meet well now. Thanks, Joe
