[QUOTE="pdqdl, post: 5326271, member: 22041"] If you turn a saw over and it runs different, you almost certainly have a crank-seal leak. Take the time to fix that before you spend a whole lot more on metal parts. The rubber parts are cheaper. BTW: many of the little vacuum pumps can be reversed to give a few pounds of pressure. 2nd option: almost all air compressors come with a regulator. Just dial into a smidge above no air pressure and that should be about right. If it reads on your tire guage, it is probably too much. 5lbs max. If no bubbles at 5, then it probably isn't going to leak vacuum, either. Too much air pressure will start making leaks! [/QUOTE]
