Hey guys, I meant sprocket not "socket" in the title I'm about 75% finished with the installation of my 66cc HT 2 stroke (www.everydaymotors.com). I just ran into my first major problem - the drive-chain seems to not fit correctly with the rear wheel sprocket. It is a 44 tooth 9-hole sprocket and it is a "415" chain (not sure what that means). Anyway, this is the chain and sprocket that came in the kit so I don't know why its not fitting. The chain will sit on the sprocket and turn a few rotations but then it wants to jump off. After closer examination I saw that I cannot wrap the drive-chain completely around the rear-wheel sprocket. For example, on the pedal chain, if I give it slack, it will wrap perfectly (360 degrees) around the socket. ---When I try to do this with the engine side, the drive-chain will wrap around about 3/4 of the way and then the teeth wind up getting misaligned and hitting the portion where the links connect (not the space where the sprocket tooth should be...) The drive-chain will, however, wrap 360 degrees perfectly around the little clutch sprocket. So this leads me to believe that I just have a faulty rear-wheel sprocket. Oh also, should the little clutch sprocket be able to free-wheel? It's really tight and I cannot turn it by hand, I have to use a screwdriver to get it to move... Any help would be GREATLY appreciated!
