it is the B and the play is in and out

my 1980 john deere sportfire 440 with a kawasaki engine. It has play in the crank and the play is in and out i have taken the engine completly apart and found that one of the crank seals is no good but what would cause the play .

I TOOK MY WHOLE ENGINE APRT AND FOUND OUT THAT THE CRANKSEAL WAS NO GOOD BEHIND THE CLUTCH. I HAVE NOT PUT THE ENGINE BACK TOGETHER YET BUT I HOPE THAT WAS ALL THAT WAS WRONG WITH IT .

THIS IS A 440 KAWASAKI AND SOME OTHER THINGS THAT HAPPEN ARE IF I GO TO GO UP A STEEP HILL IT BOGS AND THE THE POWER BAND KICKS IN . THE ONLY OTHER THAT IT DOES IS GETS HARD TO PULL OVER. ALMOST LIKE IT FREEZES UP.WITH THE MOVEMENT IN THE CRANK I REALLY DONT THINK IT IS DOING ANYTHING. BUT I COULD B...

what would the play in the crank from then

i was told it was my crankseals so i am going to try that cause i have cleaned the carb and it still does it so i will try the crank seals. That maybe why there is play in my crank like there is also

i was told that my carburator has to be cleaned. they said that it is leaking after i turn it off. another question is why when i hit the gas it boggs then it kicks the powerband

its not hard to start when hot it is after i ride for awhile then stop for a couple of hours and leave the sled outside then go and try to start it again it is hard to start. it is really hard to even pull over

would that make there be play in the crankshaft and would it make it hard to start after it has ran for a while

what happens when your center crankshaft seal is gone? Do you still get compression

my sportfire runs fine except when i ride for a while and then stop for about an hour then it wont start it is really hard to even pull over why is this
