Thanks for the replies AJMBOY and Dirtdemon,I did not do a actual compression test but what i did is I took the spark plug out and put my finger over the hole and i thought that it would have some sort of suction when I gave the pull cord a tug but there was nothing.We thought about the drive chain but then we thought that I would start anyways if the drive chain was broke.It was bad wheather here for a couple of days with as major snow storm so I will try and take the the crank case covers off and see if it is the drive chain.Thanks again for the info i will post again if anything that you guys have told me to do.Once again thanks for the info this is a great site for help keep it up..
