Don't have my book setting next to me this morning but on the 310 's hard starting can be a number of things and over heating is not one of them now as for hard starting cranking pressure of the pump and tha means that the head on the pump has more clearance then it should or slow cranking speed and that means that the starter is not getting enough juice or the bushings are getting woren , injectors are not breaking at the correct pressure or spray pattern is not sprayen wright caused by carbon build up or plug tips , low compression due to bad rings or woren sleeves or the valves are down in the head to far. late timming will make her lazy . As for checking the timming there is a window on the outside of the pump and there will be a pointer inside of that window and a scribed line on the disk that will line up when ya have the timming pointer lined up with the correct timming marks on the flywheel on the right hand side on the flywheel and to adjust you remove the plate on the ft. of the timming cover on the ft. side of the pump and there are three - four bolts in the gear with slots and you place a scoket on the center nut on the injection shaft and turn . Now finding the scribbed line at times can be a bear as if the pump has been rebuilt and new parts have been put in some pump guys do not make the line real easy to see . And the only way that you can check cranking pressure is to pull the pump and now get this is to rebuild it then check as nobody will take and old pump and put it on there stand and run it as it is as they do not want to contamenate there stand with and old dirty pump.
