I have a Coleman Powermate 7500 Watt Generator. Model #PM0557523, SN79400121. The engine is B&S Model #28N700, Type 1194E1, Code 9812032E, 14.5 HP. This generator does not have a pull cord for starting. It is supposed to have a battery. I use a battery pack to start it when I want to use it. I don't use it much so I keep a note on my computer calendar to start it up every six months. I run it for maybe a half or three quarters of an hour till the fuel runs out. The problem I have is when I am starting it. Like I said previously I run it it till it stops so it has to get fuel to the carb and that takes a lot of cranking. It will eventually start but sometimes the battery pack will run down before it does start and I then use a second battery pack. This unit might have a fuel pump but I have no parts diagram to confirm it but it does look like some kind of a pump in the fuel hose arrangement. I have no idea how it works. I was thinking of putting a manual fuel primer in the fuel line to the carb to pump fuel but I think I will wait for some answers from the forum before I do anything like that.
Thanks,
Bill
