I went ahead and bought a small impact wrench ($49.99) at Harbor Freight yesterday and charged it up. (It was an 18Volt) Anyway it didn\'t seem to budge the nut at all. When I was at Harbor Freight I noticed the one that plugs into the cigarette lighter. Should I get that one instead? The one I was using didn\'t seem very powerful (less than 100lb. / feet torque). Is there a special technique, do I need a more powerful impact wrench, or both? This is a vento phantom clone, fyi. Does the nut come off standard (counter-clockwise)?

Thanks for all your help. I talked to a local scooter shop and he said he\'s never worked on a 150cc and I was a little nervous about taking it to him (not to mention I\'d really rather do this myself since this will need to be done on a regular basis).

Thanks,
