I have a Lifelike engine just I won on eBay. The thing runs like a striped ape but it has a screech in the motor that makes my spine curl and the dog runs for the other room. I've pulled it apart, cleaned it, lubed it and put it all back together. It still has that high pitched screech that would make a Japanese schoolgirl jealous. I've got another Lifelike that runs nice and quiet with no problems and no screeching so this isn't a brand bashing thing. I just want to know how to get rid of that God awful noise.
