if it takes that long to start, while cranking, you may have a bad glow plug. thats the way mine worked. it wouldnt start without cranking 30 to 50 seconds, after the prime time.
sometimes when it would start, blue smoke would billow out
i dropped the generator, pulled the glow plugs and tested them. one had failed. i replaced all three and now it starts right away.
its a job to remove the gen, so replace the fan belt and the fuel filter while you are doing the repair.
i got all my parts from napa. the glow plugs are ngk plugs.
the number is on the side of the plug.
