Default The 1872 starts very hard, why?

When first trying to start the cub after it sat for about a week I cranked and cranked and cranked... occasionally it would try to start and then kick the starter out with out starting. I checked the fuel filter it was full of fuel I lightly pressurized the tank to get fuel to the carb still no start. As a last resort I gave it a shot of ether still didn't start until I gave it a few more shots then it finally hit but acted as though it was really starved for gas (barely running) but finally took off and ran good. I let it run for a few minutes turned it off and checked the spark plugs one was gapped at .035 the other at .025 I gapped them both at .025 like kohler specs said. They were a little carboned up but over all looked to be in good shape with no signs of oil fouling, to lean etc.The electrode was like new. I then grounded them to the block and turned the engine over they have a nice blue spark. You would think if it were a fuel problem then it would have started when I first sprayed it with ether and if it were a spark problem then I wouldn't have the good blue spark. When its running it purrs like a kitten and when I give it the throttle it roars like a lion. What am I missing, what are some of the issues that the magnums had as far a starting problems.
