With today's gas they are usually hard to start after setting for a few months. (the gas evaporates from the carb through the bowl vents) You did mention fuel pressure but not fuel pump. Do you have a electric or manual fuel pump? The electric should fill the carb up if the fuel has evaporated. A carb with a choke should help also. I usually remove the air cleaner and look fo a accelerator pump shot. If I don't see that I know I need to crank a bit. I usually crank 20 sec. or so after it sets for months just to get the oil circulated before I set the choke. tmm
