Spring on engine mount.

[Ian Williams]

Typical 750MC generated A7 folk law in my opinion, possibly some merit in certain specific circumstances but not in normal usage. Of course you will have some spring proponents who have read bulletin articles and will say oh yes essential I have run like this for hundreds of miles and have less block leaks and no broken studs etc. But there are plenty of people out there who quietly put their engines together properly, use no spring, and do thousands of miles with no issues what so ever. So put a spring on and bolt that make's you feel happy, if you arn't trailing or racing it won't make a blind bit of difference, and if you are racing it will probably make you go slower round corners.
