I took advantage of the cheap pins from Dragon carp and ordered one, I've never used them before. I was advised to strip them down and give them a quick oil before I use them for the first time, I was told this would help them spin. I was told sewing machine oil or 3 in 1 was a good oil to use. I could only get what was called 'fine' oil, the fella in the shop said it was used on sewing machines. I was getting about a minute spin I'm now down to 30 seconds, is this normal? Does the oil need time to work? If the oil I've used is the wrong stuff then how do I go about cleaning it off the bearings?
