I have a Mighty Flea and enjoy it, but man, is it hard to keep it running properly!
I know how to clean and lube a bearing, but I find it to be almost impossible to keep it running unresponsive consistently. My freshly cleaned bearing becomes responsive after around 2-5 minutes of play! I use acetone or methylated spirits and terrapin dry for lube.
Do any of you guys have the same difficulty? Any suggestions?
